Do not apply directly to water, to areas where surf ace water is present, or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment wash water or rinsate.

2,4-D has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, partic ularly where the water table is shallow, may result in

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 3 groundwater contamination. Application around a cis tern or well may result in contamination of drinkin g water or groundwater.

Groundwater Contamination: Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-D have been associated with mixing/loading a nd disposal sites. Caution should be exercised when handling 2,4-D pesticides at such sites to prevent contamination of groundwater supplies. Use of close d systems for mixing or transferring this pesticide w ill reduce the probability of spills. Placement of the mixing/loading equipment on an impervious pad to co ntain spills will help prevent groundwater contamination.

RESISTANCE MANAGEMENT

For resistance management, HM-1604 HERBICIDE is a Group 4 mode of action herbicide containing 2, 4-D acid and dicamba acid. Any weed population may cont ain or develop plants naturally resistant to HM-1604 HERBICIDE and other Group 4 mode of action herbicides. The re sistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance managemen t strategies should be followed.

To delay herbicide resistance, take one or more of the following steps:

 Rotate the use of HM-1604 HERBICIDE or other Group 4 herbicides within a growing seaso n sequence or among growing seasons with different he rbicide groups that control the same weeds in a field.

 Use tank-mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is available, use the less resistance-prone partner at a rate tha t will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor i f you are unsure as to which active ingredient is currently less prone to resistance.

 Adopt an integrated weed-management program for he rbicide use that includes scouting and uses historical information related to herbicide use and crop rotation, and that considers tillage (or othe r mechanical control methods), cultural (e.g., higher crop seeding rates; precision fertilizer applicati on method and timing to favor the crop and not the wee ds), biological (weed-competitive crops or varieties) and other management practices.

 Scout before and after herbicide application to mo nitor weed populations for early signs of resistanc e development. Indicators of possible herbicide resis tance include: (1) failure to control a weed species normally controlled by the herbicide at the dose ap plied, especially if control is achieved on adjacen t weeds; (2) a spreading patch of non-controlled plan ts of a particular weed species; (3) surviving plants mixed with controlled individuals of the sam e species. If resistance is suspected, prevent weed seed production in the affected area by an alt ernative herbicide from a different group or by a mechanical method such as hoeing or tillage. Preven t movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.

 If a weed pest population continues to progress af ter treatment with this product, discontinue use of this product, and switch to another management stra tegy or herbicide with a different mode of action, if available.

 Contact your local extension specialist or certifi ed crop advisors for additional pesticide resistanc e- management and/or integrated weed-management recomm endations for specific crops and weed biotypes.

 For further information or to report suspected resistance, contact Helena Agri-Enterprises, LLC representatives at (901) 761-0050.

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 5

Fields should be scouted prior to application to identify the weed species present and their growth st age to determine if the intended application will be effective.

Fields should be scouted after application to verif y that the treatment was effective.

Suspected herbicide-resistant weeds may be identified by these indicators:  Failure to control a weed species normally control led by the herbicide at the dose applied, especiall y if control is achieved on adjacent weeds;  A spreading patch of non-controlled plants of a pa rticular weed species; and  Surviving plants mixed with controlled individuals of the same species.

Report any incidence of non-performance of this product against a particular weed species to your Hele na Agri-Enterprises retailer, representative or call 901-761-0050. If resistance is suspected, treat weed escapes with an herbicide having a different mechanism of a ction and/or use non-chemical means to remove escapes, as practical, with the goal of preventing further seed production.

Plant into weed-free fields and keep fields as weed-free as possible.

To the extent possible, use a diversified approach toward weed management. Whenever possible incorporate multiple weed-control practices such as mechanical cultivation, biological management prac tices, and crop rotation.

Fields with difficult to control weeds should be rotated to crops that allow the use of herbicides with alternative mechanisms of action or different management practices.

To the extent possible do not allow weed escapes to produce seeds, roots or tubers. Manage weed seeds at harvest and post-harvest to prevent a buildup of the weed seed-bank.

Prevent field-to-field and within-field movement of weed seed or vegetative propagules. Thoroughly cle an plant residues from equipment before leaving fields.

Prevent an influx of weeds into the field by managing field borders.

Identify weeds present in the field through scouting and field history and understand their biology. T he weed- control program should consider all of the weeds pr esent.

Difficult to control weeds may require sequential applications of herbicides with differing mechanisms of action.

Apply this herbicide at the correct timing and rate needed to control the most difficult weed in the f ield.

Use a broad spectrum soil-applied herbicide with a mechanism of action that differs from this product as a foundation in a weed-control program. Do not use mo re than two applications of this or any other herbicide with the same mechanism of action within a single growing season unless mixed with an herbicide with another mechanism of action with an overlapping spectrum for the difficult-to-control weeds.

If resistance is suspected, treat weed escapes with an herbicide with a different MOA or use non-chemi cal methods to remove escapes.

Contact your local sales representative, crop advisor, or extension agent to find out if suspected resistant weeds to these MOAs have been found in your region. Do not assume that each listed weed is being controlled by multiple mechanisms of action. Co-formulated active ingredients are intended to broaden the spectrum of weeds that are controlled. Some weeds m ay be controlled by only one of the active ingredient in this product.

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 6 PRODUCT INFORMATION

HM-1604 HERBICIDE is a postemergence herbicide for controlling a wid e spectrum of annual, biennial, and perennial broadleaf weeds and brush in pastures, ra ngeland, and grass (hay, silage); sorghum; wheat; conservation reserve program land; postharvest, fal low, crop stubble, set-aside acres; general farmste ad areas; certain noncrop areas; and for forest management.

Mode of Action

HM-1604 HERBICIDE contains two active ingredients uniquely formulate d to be used alone or tank mixed with other listed products as well as liquid fertil izer solutions. HM-1604 HERBICIDE is readily absorbed by plants through shoot and root uptake, translocates throughout the plant’s system, and accumulates in a reas of active growth. HM-1604 HERBICIDE interferes with the plant’s growth hormones (auxin s) resulting in death of many broadleaf weeds.

For best results, thoroughly clean sprayer equipmen t (tank, lines and nozzles) immediately after use b y flushing system with water and heavy duty detergent or other suitable tank cleaner.

APPLICATION INSTRUCTIONS

Apply HM-1604 HERBICIDE at the rates and growth stages listed in Tables 1 and 2 as follows unless instructed differently by section on “ Food/Feed Crop Specific Information ” or “ Non-Food/Feed Use (Land not Harvested, Grazed or Foraged)-Specific Informat ion .” Use either water or sprayable liquid fertilizer as a carrier for HM-1604 HERBICIDE. Use sprayable liquid fertilizer as the carrier in preplant or pre- emergence use for all crops listed on this label. Postemergence uses with sprayable fluid fertilizer may be made on pasture, hayland, or wheat crops only. Th e most effective application rate and timing varies based on the target weed species (refer to Table I). In mixed populations of weeds the correct rate is dete rmined by the weed species requiring the highest rate. De laying application permits weeds to exceed the maxi mum size and will prevent adequate control. For certain specified applications liquid fertilize r or oil may replace part or all of the water as diluent. If dry flowabl e (DF), wettable powder (WP) or flowable (F) tank m ix products are to be used, these should generally be added to the spray tank first. It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions, limitations , and directions for use on all product labels invo lved in the tank mixture. Users must follow the most restrictiv e directions for use and precautionary statements o f each product in the tank mixture.

Apply product only when active weed growth is evident.

CHEMIGATION PROHIBITION

Do not apply this product through any type of irrigation system.

Spray Coverage:

Weeds must be thoroughly covered with spray. Dense leaf canopies shelter smaller weeds and prevent adequate spray coverage.

Sensitive Crop Precautions:

HM-1604 HERBICIDE may cause injury to desirable trees and plants, pa rticularly beans, cotton, flowers, fruit trees, grapes, ornamentals, peas, potatoes, soybean s, sunflowers, tobacco, tomatoes and other broadlea f plants when contacting their roots, stems or foliag e. At high temperatures (about 85 degrees or higher ), vapors from this product may cause injury to the af orementioned susceptible crops. These plants are m ost sensitive to HM-1604 HERBICIDE during their development or growing stage. Do not treat areas where either possible downward movement into the soil or surface washing may cause contact of HM-1604 HERBICIDE with the roots of desirable trees and shrubs.

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 7 Drift Reduction Information:

The following information may be helpful in reducin g possible spray drift from ground or aerial applic ations. Avoid making applications when spray particle may b e carried by air currents to areas where sensitive crops and plants are growing. Do not spray near sensitiv e plants if the wind is gusty or in excess of 5 mph and moving in the direction of nearby sensitive crops o r if a temperature inversion exists. Always determ ine the direction and distance of possible spray drift prio r to application. Leave an adequate buffer zone bet ween area to be treated and sensitive plants. Coarse sp rays are less likely to drift out of the target are a than fine sprays. Properly maintain and calibrate all spray e quipment. The use of agriculturally accepted drift retardants are acceptable and advised. Avoid applic ations within the vicinity of susceptible plants wh en at all possible. Do not apply in greenhouses.

AERIAL APPLICATION METHODS AND EQUIPMENT

Water Volume: Use 3-10 gallons of water per acre. Use the highe r spray volume when treating dense or tall vegetation.

Application Equipment: Select nozzles designed to produce minimal amounts of fine spray particles. Make applications at the lowest stage height to reduce t he exposure of spray droplets to evaporation and wi nd. The applicator must follow the most restrictive use precautions to avoid drift hazards, including thos e found in the this labeling as well as applicable state and local regulations and ordinances.

SPRAY DRIFT MANAGEMENT

A variety of factors including weather conditions (e.g. wind direction, wind speed, temperature, relative humidity) and method of application (e.g., ground, aerial, and airblast) can influence pesticide drift. The applicator must evaluate all factors and make appropriate adjustments when applying this product.

Droplet Size

When applying sprays that contain 2,4-D as the sole active ingredient, or when applying sprays that c ontain 2,4-D mixed with active ingredients that require a Coarse or coarser spray, apply only as a Coarse o r coarser spray (ASABE standard 572) or a volume mean diameter of 385 microns or greater for spinning atomizer nozzles.

When applying sprays that contain 2,4-D mixed with other active ingredients that require a Medium or more fine spray, apply only as a Medium or coarser spra y (ASABE standard 572) or a volume mean diameter of 300 microns or greater for spinning atomizer nozzles.

Wind Speed

Do not apply at wind speeds greater than 15 mph. Only apply this product if the wind direction favors on- target deposition and are not sensitive areas (including, but not limited to, residential areas, bodies of water, known habitat for nontarget species, nontarget crops) within 250 feet downwind. If applying a Medium spray, leave one swath unsprayed at the downwind edge of t he treated field.

Temperature Inversions

If applying at wind speeds less than 3 mph, the app licator must determine if: a) conditions of temperature inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not make app lications into areas of temperature inversions or stable atmo spheric conditions.

2,4-D esters may volatize during conditions of low humidity and high temperatures. Do not apply during conditions of low humidity and high temperatures

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 8 Susceptible Plants

Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale , use or consumption. Susceptible crops include, but are not limited to cotton, okra, flowers, grapes (in growing stage), fruit trees (foliage), soybeans (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables, or tobacco. Small amounts of spray drift that might not be visible may injure susceptible broadleaf plants.

Other State and Local Requirements

Applicators must follow all state and local pesticide drift requirements regarding application of 2,4- D herbicides. Where states have more stringent regulations, they must be observed.

Equipment

All aerial equipment and ground application equipme nt must be properly maintained and calibrated using appropriate carriers or surrogates.

For aerial equipment, the boom length must not exce ed 75% of the wingspan or 90% of the rotor blade diameter.

Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet above the crop canopy unless a greater height is required for aircraft safety. This requirement does not apply to forestry or rights-of-way applications. When applications are made in a crosswind, the swat h will be displaced downwind. The applicator must compensate for this by adjusting the path of the aircraft upwind.

For ground boom application, do not apply with a nozzle height greater than 4 feet above the crop canopy.

SENSITIVE AREAS

The pesticide should only be applied when the poten tial for drift to adjacent sensitive areas (e.g. re sidential areas, bodies of water, known habitat for threatene d or endangered species, non-target crops) is minim al (e.g. when wind is blowing away from the sensitive areas).

For increased control of weeds such as blackberry and dewberry, HM-1604 HERBICIDE may be tank mixed with metsulfuron- methyl, if labeled for the use site.

Ground Application (Banding) Do not apply with a nozzle height greater than 4 feet above the crop canopy.

When applying HM-1604 HERBICIDE by banding, determine the amount of herbicide and water volume needed using the following formula:

Bandwidth in inches x Broadcast rate = Banding herbicide Row width in inches per acre rate per acre

Bandwidth in inches x Broadcast rate = Banding water Row width in inches volume per acre volume per acre

Ground Application (Broadcast)

Water volume : Use 10-25 gallons of spray solution per broadcast acre for optimal performance. Use the higher spray volume when treating dense or tall vegetation.

Application Equipment : Select nozzle design to produce minimal amounts o f fine spray particles. Spray nozzles as close to the weeds as is practical for good weed coverage.

Spot or Small Area Application

HM-1604 HERBICIDE may be applied to individual clumps or small areas of undesirable vegetation using handgun or similar types of application equipment. Apply diluted sprays to allow complete wetting (up to runoff) of foliage and stems. For knapsack or othe r small capacity sprayers, prepare a solution of HM-1604 HERBICIDE in water according to Table 3 (assuming that the s pot treatment rate equates to 40 gallons pre acre on the broadcast basis.) Adding a surfactant (0.5% by volume) can help improve control.

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 12 Do not make spot treatments in addition to broadcast or band treatments.

Application equipment: Select nozzles designed to p roduce minimal amounts of fine spray particles. Sp ray with nozzles as close to the weeds as is practical for good weed coverage.

ADDITIVES

To improve burndown of emerged weeds, surfactants a nd/or low use rates of liquid fertilizers (28-0-0; 32-0- 0), or crop oil concentrate may be used with HM-1604 HERBICIDE or HM-1604 HERBICIDE tank mixes applied after the weeds have emerged. Crop oil con centrate is for non-food/feed crop uses only. Do n ot apply tank mixes that include Ammonium Sulfate or C rop Oil Concentrate to any food/feed crop use liste d on this label. For food/feed crop use, do not use liq uid fertilizers that contain Ammonium Sulfate (AMS) as a source of nitrogen as tolerances in commodities der ived from the crop may contain residues that exceed established tolerances.

Oil Concentrate

A crop oil concentrate must contain either a petrol eum or vegetable oil base and must meet all of the following criteria:

 be non-phytotoxic  provide good mixing quality in the jar test, and  be successful in local experience

The exact composition of suitable products will var y; however, vegetable oil and petroleum oil concent rates should contain emulsifiers to provide good mixing q uality. Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils. For ad ditional information, see Compatibility Test for Mi x Components.

Adjuvants containing crop oil concentrates may be u sed for preplant, pre-emergence and between croppin g applications. Do not use crop oil concentrate for p ostemergence applications to food/feed crops (i.e. sorghum, grass (hay or silage), pastures, rangeland, and wheat.

Nitrogen Source

Sprayable liquid fertilizers: Use ½ GPA of sprayabl e liquid fertilizers (28-0-0; 32-0-0) per acre. Do not use brass or aluminum nozzles when spraying fertilizers.

Non-ionic Surfactant

The standard label rates are 2-4 pints of an 80% ac tive non-ionic spray surfactant per 100 gallons of water. (Rate will vary with the size and condition of weed s to be controlled. Use lowest rate per 100 gallon s when weeds are small and actively growing. As weeds inc rease in size and or become hardened off, the rate of non-ionic surfactant will have to be increased to give optimum coverage and control.)

TANK MIXING INFORMATION

Tank Mix Partners/Components It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

The following products may be tank mixed with HM-1604 HERBICIDE according to the specific tank mixing instructions in this label and respective product labels.

2,4-D 1 diflufenzopyr picloram alachlor diuron pronamide ametryn fenoxaprop-p-ethyl prosulfuron asulam glyphosate quinclorac atrazine halosulfuron-methyl terbacil bentazon metribuzin thifensulfuron-methyl carfentrazone-ethyl metsulfuron-methyl triasulfuron clopyralid MCPA tribenuron-methyl chlorsulfuron paraquat

*When tank mixing with products that contain either 2,4-D or dicamba, do not exceed the annual per acr e application rate for each active ingredient for that crop.

See “ Food/Feed Crop Specific Information ” section for more information for more details. R ead and follow the applicable Restrictions and Limitations and Dir ections for Use on all products involved in tank mi xing. Physical incompatibility, reduced weed control, or crop injury may result from mixing HM-1604 HERBICIDE with other pesticides (fungicides, herbicides, inse cticides, or miticides), additives, or fertilizers. Therefore always determine compatibility before tan mixing this product with any other pesticide.

Compatibility Test for Mix Components

Before mixing components, always perform a compatib ility jar test.

For 20 gallons per acre spray volume, use 3.3 cups (800 ml) of water. For other spray volumes adjust accordingly. Only use water from the intended source at the source temperature.

Add components in the sequence indicated in the Mix ing Order using 2 teaspoons for each pound or 1 teaspoon for each pint of specified label rate per acre.

Always cap the jar and invert 10 cycles between com ponent additions.

When the components have all been added to the jar, let the solution stand for 15 minutes. Evaluate t he solution for uniformity and stability. The spray s olution should not have free oil on the surface, no r fine particles that precipitate to the bottom, nor thick (clabbered) texture. If the spray solution is not compatible,

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 14 repeat the compatibility test with the addition of a suitable compatibility agent. If the solution is still incompatible, do not mix the ingredients in the same tank.

Mixing Order: If an inductor is used, rinse it thoroughly after each component has been added. Maintain constant agitation during application.

1. Water. Begin by agitating a thoroughly clean spr ayer tank half full of clean water.
2. Agitation. Maintain constant agitation througho ut mixing and application.
3. Products in PVA bags. Place any product contain ed in water-soluble bags into the mixing tank. Wai t until all water-soluble PVA bags have fully dissolv ed and the product is evenly mixed in the spray tan k before continuing.
4. Water-dispersible products (such as dry flowable s, wettable powders, suspension concentrates, and suspo-emulsions)
5. Water-soluble products (such as HM-1604 HERBICIDE ).
6. Emulsifiable concentrates (such as oil concentra te, when applicable).
7. Water-soluble additives (such as liquid fertiliz ers (28-0-0; 32-0-0), when applicable).*
8. Remaining quantity of water.

• If sprayable fluid fertilizer is used as the carrier.

Always perform the Compatibility Test before mixing into the spray tank. Also, when using a sprayable fluid fertilizer as the carrier, any product contained in PVA bags must first be completely dissolved in wat er before the contents can be added to the fertilizer mix.

PRECAUTIONS

 Arid (dry) conditions: it is extremely important t hat the addition of a suitable Nonionic Surfactant, Oil, or sprayable fertilizer be used when applying HM-1604 HERBICIDE . Higher rates of HM-1604 HERBICIDE may be needed to control susceptible weeds in this environment.  Rainfast Period: Rainfall or irrigation occurring within 4 hours after postemergence applications ma y reduce effectiveness of HM-1604 HERBICIDE .  Stress: Do not apply to crops under stress such a s stress due to lack of moisture, hail damage, floo ding, herbicide injury, mechanical injury, or widely fluc tuating temperatures, as unsatisfactory control may result.

FOOD/FEED CROP SPECIFIC INFORMATION

PASTURES, RANGELAND AND GRASS (HAY, SILAGE)

HM-1604 HERBICIDE is for use on pasture (including pasture grown for hay), rangeland, and grass grown for hay or silage, between crop applications/fallow systems, Conservation Reserve Programs, and genera l farmstead (non-cropland only).

Refer to Tables 1 and 2 for rate selection based on targeted weed or brush species. Some weed species will require tank mixes for adequate control.

For pasture renovations, wait 3 weeks per 1 1/4 pin ts of HM-1604 HERBICIDE used per acre before interseeding or injury may occur.

Uses described in this section also pertain to smal l grains (such as barley, corn, forage sorghum, oat s, rye, sudangrass, or wheat) grown for pasture, hay, and s ilage only. Newly seeded areas including small gra ins grown for pasture or hay, may be injured if rates o f HM-1604 HERBICIDE are greater than 1 1/4 pints per acre are applied in one application.

In newly established hybrid Bermudagrass, Pangolagr ass, and stargrasses ( Cynodon spp.) use 1 to 2 pints of HM-1604 HERBICIDE per acre to control or suppress weeds after planti ng vegetative propagules (stolons) of hybrid bermudagrasses. In addition to the weeds listed in Tables 1 and 2, this rate of HM-1604 HERBICIDE will control or suppress annual sedges, broadleaf signalgrass, crabgrass, and goosegrass. Best results will be obtained if HM-1604 HERBICIDE is applied at the germinating stage of weeds. Und er favorable conditions, this is usually 7-10 days aft er planting these grasses. Reduced control can be expected if weeds are allowed to reach 1” in height before application or if germination of weeds occu rs 10 days after application.

Use on bentgrass, susceptible grass pastures (such as carpetgrass, buffalograss, or St. Augustine gras s), lespedeza, wild winter peas, vetch, clover, and alfalfa pastures may result in some degree of plant injury.

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 16 When perennial weeds are reaching maturity, mowing and allowing some regrowth will enhance control.

BETWEEN CROP APPLICATIONS

Preplant Directions (Postharvest, Fallow, Crop Stub ble, Set-Aside) For Broadleaf Weed Control

HM-1604 HERBICIDE can be applied postharvest in the fall, spring, or summer during the fallow period or to crop stubble/set-aside acres. Apply to weeds after crop harvest (postharvest) and before a killing fr ost or in the fallow cropland or crop stubble the following spring or summer.

See “ Restrictions and Limitations ” for the specified interval between application an d planting to prevent crop injury.

Rates and Timings:

Apply 1 – 3 2/3 pints of HM-1604 HERBICIDE per acre. Refer to Table 1 to determine use rates for specific targeted weed species. Retreatments may be made as needed; however, do not exceed a total of 4 3/4 pints of HM-1604 HERBICIDE per treated acre during a growing season. For bes t performance, apply HM- 1604 HERBICIDE when annual weeds are less than 6" tall, when bien nial weeds are in the rosette stage and to perennial weed regrowth in late summer or fall f ollowing a mowing or tillage treatment. The most e ffective control of upright perennial broadleaf weeds such a s Canada thistle and Jerusalem artichoke occurs if HM- 1604 HERBICIDE is applied when the majority of weeds have at leas t 4-6" of regrowth or for weeds such as field bindweed and hedge bindweed that are in or be yond the full bloom stage. The addition of liquid fertilizers (28-0-0, 32-0-0) at ½ GPA has shown to increase efficacy.

Do not disturb treated areas following application. Treatments may not kill weeds that develop from s eed or underground plant parts such as rhizomes or bulblet s, after the effective period for HM-1604 HERBICIDE . For seedling control, a follow-up program or other cultural practices could be instituted.

FOREST MANAGEMENT

Forest Site Preparation

Budbreak Spray: For control of alder, susceptible broadleaf weeds, and susceptible woody plants before planting forest seedlings, apply up to 2 quarts per acre in a minimum of 10 gallons spray mixture per acre. Apply as an oil spray (see " Mixing Instructions ") after alder buds break, but before foliage is 1/ 4 full size. A water spray including 2 to 4 quarts per acre of die sel oil, fuel oil, stove oil, or crop oil concentra te may also be used.

Foliage Spray: To control alder and susceptible woody plants bef ore planting forest seedlings, apply up to 4 pints per acre in a minimum of 10 gallons spray mix ture per acre. If desired, apply as a water spray including up to 1 quart of diesel oil, fuel oil, stove oil, o r crop oil concentrate per gallon of water (see "Mi xing Instructions"). For best results, apply after alder foliage has reached full size.

Conifer Release: Some Conifers are more susceptible to HM-1604 HER BICIDE than others. To control alder, susceptible broadleaf weeds, and susceptible woody plants in young conifer stands, apply up to 2 pints per acre in a minimum of 10 gallons spray mix ture per acre. Apply this spring foliage treatment as a water spray when 3/4 of the brush foliage has full size leaves and before new conifer growth reaches 2 inches in length. Such stages usually occur betwee n early May and mid-June, but base application timi ng on growth stages of brush and conifers. Application m ay cause leader deformation and other conifer injur y, but trees should overcome it during the next growing season.

To control tanoak, madrone, ceanothus, canyon live oak, and manzanita, and to release Douglas fir, hemlock, Sitka spruce or grand fir, apply up to 3 p ints per acre in a minimum of 10 gallons spray mixt ure per acre. Apply this spring foliage treatment as a wat er spray including, if desired, up to 1 quart of di esel oil, fuel oil, stove oil, or crop oil concentrate per gallon of water (see " Mixing Instructions "). Make application before new growth on Douglas fir is 2 inches long. To release ponderosa pine from the same species, t reat before new pine growth begins in the spring. Addit ion of oil or oil concentrate may cause unacceptabl e injury to pines. For dormant applications in late winter or early spring for control of susceptible woody sp ecies such

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 21 as alder, willow, poplars, cherry, vine maple, cean othus, tanoak, madrone, and manzanita, apply up to 3 pints per acre in a minimum of 10 gallons spray mix ture (with diesel oil, etc.) per acre. Apply this dormant treatment in diesel oil, fuel oil, stove oil, or ot her suitable diluent such as water plus crop oil co ncentrate (see "Mixing Instructions"). Do not use in plantations where pine and larch are among the desired crop species.

To control hazel dodder ( cuscuta coryli ) in the Lake states, apply up to 2 pints per acre in a minimum of 10 gallons spray mixture per acre. Apply as a water s pray when new shoot growth of hazel is complete (us ually mid-July).

After conifer species such as white pine, ponderosa pine, jack pine, red pine, black spruce, white spr uce, red spruce, and balsam fir crease growth and harden off and brush is still actively growing in late summer , apply up to 3 pints per acre in a minimum of 10 gallons w ater spray mixture per acre. Apply as a water spra y to control certain competing hardwoods such as alder, aspen, birch, hazel and willow. However, if possib le injury cannot be tolerated, do not use since this treatment may cause conifer injury.

Forest Roadsides: To control susceptible broadleaf weeds and woody plants on forest roadsides, apply 1 to 3 pints per acre in a minimum of 10 gallons wate r spray mixture per acre. Apply as a water spray a nd, if necessary to ensure penetration of foliage, include up to 3 quarts per acre of diesel oil, fuel oil, s tove oil, or crop oil concentrate (see "Mixing Instructions").

For control of listed broadleaf weeds and small woo dy plants, apply 2/3 to 2 pints per acre diluted in 10 gallons of water. Use the high rate for woody plan ts. Applications may be as broadcast sprays, small area sprays or spot treatments. For small areas or spot spraying, use 2 fluid ounces per gallon of water a nd spray weeds to runoff. Regardless of the method of appli cation, use adequate spray volume for full coverage of weeds. Application timing is in the early spring w hen sufficient weeds have emerged, and when weeds a re small and actively growing, but before weeds exceed size limits described in weed tables. Summer applications to older, drought-stressed weeds are l ess effective. However, listed weeds are more susceptible again in the fall when cooler, wetter c onditions support active growth before a killing fr ost. For fall treatment of mature weeds or perennial weed re growth, use up to 1.0 pints per acre diluted in 10 gallons of water. Several seasons of spring plus fall trea tments may be necessary to control certain listed perennials. Use of oil sprays or the addition of s pray adjuvants improves weed control, but also incr eases the risk of damage to desirable ground covers.

Precautions : Plant Response : Bent grass, other warm season or southern grasses , alfalfa, clover, or other legumes may be killed or injured.

In addition to weed s pecies listed in Tables 1 and 2, these treatments may be u sed to control or suppress woody plant species list ed in Table 7.

To prepare soil and water emulsions, mix in the ord er and proportions indicated below.

1. Water: Begin by agitating a thoroughly clean sp rayer tank with the desired quantity of clean water . Maintain constant agitation during complete mixing procedure.
2. Emulsifier: Add 0.5% volume to volume of water.
3. HM-1604 HERBICIDE : add 1.5 gallons per 100 gallons of total intended solution.
4. Diesel Oil: Add 10 gallons per 100 gallons of to tal intended solution.

One gallon of HM-1604 HERBICIDE in forty gallons of spray solution contains 1.0 pounds acid equivalent of dicamba and 2.3 pounds acid equivalent of 2,4-D. Spray plants to wet.

Filename: HM-1604 Herbicide (5905-AUG) 120321 CLN 23 The solution should remain milky colored without an oily layer on top when under agitation. If an oil y layer forms, increase the amount of emulsifier or change to a more effective emulsifier.

To control listed brush, briars, and weeds along fence-rows surrounding pasture and ranch lands, and f allow fields, use a tank mix of 1.5% HM-1604 HERBICIDE , 88.5% water, 10% diesel oil, and sufficient emuls ifier (to mix the diesel and emulsifier). The diesel oil in this tank mix will damage or kill desirable grasses, do not use in pastures or where damage to desirable species cannot be tolerated.

Maintain constant agitation during application. Under good agitation, the spray solution should be milky white with no oil layer on top. If oil layer forms , increase the amount of emulsifier or change to a more effective emulsifier.

FOR SPRAYING FOLIAR APPLICATIONS :
