GENERAL INFORMATION 
Landmaster II herbicide is a postemergence herbicide for control or suppression of emerged weeds in fallow 
and reduced tillage systems, prior to planting or emergence of barley, field corn, oats, rye, sorghum (grain or 
forage), or wheat, and as a spot treatment in barley, field corn, forage grasses, forage legumes, oats, rye, 
sorghum, and wheat. • 
Do not harvest or feed treated vegetation for 8 weeks after application. Following spot treatment in forage 
grasses or legumes, allow 30 days before harvesting or grazing domestic livestock. 
This product enters the plant through the foliage and moves throughout the plant. Visual effects of control are 
a gradual wilting or yellowing of the plant that advances to complete browning of above ground growth and 
deterioration of affected underground plant parts. Visible symptoms will usually develop on weeds listed on 
this label within 2 to 4 days after application, but may not occur for 7 or more days. Extremely cool or cloudy 
weather following treatment may slow activity of this product and delay the visual effects of control. 
Application Precautions and Restrictions 
• Do not plant any crop other than barley, field corn, oats, rye, sorghum (grain or forage), or wheat for 3 
months after treatment. 
• Application of this product after planting and prior to crop emergence may cause crop injury if rainfall or 
environmental conditions delay crop emergence. 
• This product is recommended for control of emerged weeds prior to establishment of crops listed on this 
label. Large amounts of green or decaying vegetation left standing or incorporated into the seedbed may 
enhance the development of disease in newly planted crops. This may result in poor emergence and/or 
stands, especially under cool and/or wet conditions. 
• Observe individual and total maximum application rates of 2,4-0 (acid equivalents) listed throughout this 
label. These maximum rates are for the total amount of 2,4-0 applied using this product and any other 
2,4-0 containing product applied either separately or in a tank-mix with this product. 
• Spraying early to control young weeds before dense stands develop, or light cultivation to assist weed 
decay, will favor preparation of suitable seedbeds. 
• In reduced tillage and no-till systems, ensure good seed to soil contact and proper seeding depth. 
• Do not feed or forage vegetation from treated areas for 8 weeks following application. 
• DO NOT APPLY IN THE VICINITY OF 2,4-D SENSITIVE CROPS SUCH AS COTTON, GRAPES, 
TOMATOES AND OTHER DESIRABLE VEGETATION. 
• Application should be made only when there is no hazard from spray drift, as very small quantities of this 
herbicide spray, which may not be visible, can severely injure susceptible crops or desirable vegetation. 
EPA Reg. No. 524-376 Page 6 of 16 Revised May 2009 
7 -l 1

• Movement of this product on soil particles during windstorms may cause damage to susceptible plants 
that are contacted. This hazard is reduced if rainfall occurs shortly after application. 
• Buyer and all users are responsible for all loss or damage in connection with the use or handling of 
mixtures of this herbicide or other materials that are not expressly recommended in this labeling. Mixing 
this product with herbicides or other materials not recommended on this label may result in reduced 
performance. Use of this product in any manner not consistent with this label may result in injury to 
persons, animals or crops, or other unintended consequences. 
Landmaster II herbicide is subject to all state and county regulations for 2,4-0 amine. 
Mixing Instructions 
Landmaster II Herbicide Alone 
Fill the spray tank to about 75 percent of the desired volume with clean water. Add the appropriate amount of 
this product, then complete the filling process while maintaining agitation. Remove the hose from the mix tank 
immediately after filling to avoid siphoning back into the carrier source. During mixing and application, 
foaming of the spray solution may occur. To prevent or minimize foam, terminate by-pass and return lines at 
the tank bottom and/or use an agriculturally approved anti-foam or defoaming agent. 
Additional surfactant is not recommended for this formulation. 
NOTE: Reduced control may occur if water containing soil is used, such as water from ponds and unlined 
ditches. 
Tank Mixtures 
Always predetermine the compatibility of all tank-mix products together in the carrier by mixing small 
proportional quantities in advance. 
Prepare tank mixtures of this product in water as follows: 
1. Place a 20- to 35-mesh screen or wetting basket over filling port. 
2. Through the screen, fill the sprayer tank one-half full with water and start agitation. 
3. If a wettable powder is used, make a slurry of it with water and add it SLOWLY through the screen into 
the tank. Continue agitation. 
4. If a flowable formulation is used, premix one part flowable with one part water. Add this diluted mixture 
SLOWLY through the screen into the tank. Continue agitation. 
5. If an emulsifiable concentrate formulation is used, premix one part emulsifiable concentrate with two 
parts water. Add this diluted mixture SLOWLY through the screen into the tank. Continue agitation. 
6. Continue filling the sprayer tank with water and add the required amount of this product near the end of 
the filling process. 
7. Add individual formulations to the spray tank as follows: wettable powder, flowable, emulsifiable 
concentrate, drift control additive and water soluble liquid (this product). 
Maintain good agitation at all times until the contents of the tank are sprayed. If the spray mixture is allowed 
to settle, thorough agitation is required to re-suspend the mixture before spraying is resumed. 
Keep by-pass line on or near bottom of tank to minimize foaming. Screen size in nozzle should be no finer 
than 100 mesh and in-line strainers should be no finer than 50 mesh. Carefully select proper nozzle to avoid 
spraying a fine mist. For best results with conventional ground application equipment, use flat fan nozzles. 
Check the label of all products used in a tank-mix for cleaning instructions. Clean equipment according to the 
directions for the material hardest to remove from spray and mixing equipment. 
Ammonium Sulfate 
The addition of 1 to 2 percent dry ammonium sulfate by weight (or liquid equivalent) may increase the 
performance of tank mixtures of this product on annual weeds. Add 8.5 to 17 pounds of dry ammonium 
EPA Reg. No. 524-376 Page 7 of16 Revised May 2009

sulfate per 100 gallons of spray solution. The improvement in performance may be apparent where 
environmental stress is a concern. Use the higher rate of ammonium sulfate with this product when treating 
dense populations or large weeds. Low-quality ammonium sulfate may contain material that will not readily 
dissolve, which could result in nozzle tip plugging. To determine quality, perform a jar test by adding one-third 
cup of ammonium sulfate to 1 gallon of water and agitate for 1 minute. If undissolved sediment is observed, 
pre-dissolve the dry additive in water and filter prior to addition to the spray tank. If ammonium sulfate is 
added directly to the spray tank, add slowly with agitation. Adding too quickly may clog outlet line. ENSURE 
THAT AMMONIUM SULFATE IS COMPLETELY DISSOLVED IN THE SPRAY TANK BEFORE ADDING 
HERBICIDES. THOROUGHLY RINSE THE SPRAY SYSTEM WITH CLEAN WATER AFTER USE TO 
REDUCE CORROSION. OBSERVE ALL PRECAUTIONARY STATEMENTS ON THE AMMONIUM 
SULFATE PRODUCT LABELS. 
NOTE: Compatibility problems may occur at carrier volumes below 5 GPA. 
Hand-Held Sprayers 
Prepare the desired volume of spray solution by mixing the amount of this product in clean water as shown in 
the following table:

Do not apply this product through any type of irrigation system. 
This product may be applied using either ground or aerial spray equipment. Use extreme care to avoid 
misting or drifting of herbicide solution onto foliage, green stems or fruit of desirable crops, trees, or plants 
during both growing and dormant periods, since even very small quantities of spray can cause severe plant 
injury. 
SPRAY DRIFT MANAGEMENT 
A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, and 
relative humidity) and method of application (e.g., ground, aerial, airblast, and chemigation) can influence 
pesticide drift. The applicator and grower 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 
contain 2,4-D mixed with active ingredients that require a coarse or coarser spray, apply only as a Coarse 
or coarser spray (ASAE 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 spray (ASAE 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 10 miles per hour. Only apply this product if the wind direction 
favors on-target deposition and there 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 the treated field. 
Temperature Inversions 
If applying at wind speeds less than 3 miles per hout, the applicator must determine if: a) conditions of 
temperature inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not 
apply into areas of temperature inversions or stable atmospheric conditions. 
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 may not even be visible can injure susceptible broad leaf 
plants. 
Other State and Local Requirements 
Applicators must follow all state and local pesticide drift requirements regarding application of 2,4-0 
herbicides. Where states have more stringent regulations, they must be observed. 
Equipment 
All aerial and ground application equipment must be properly maintained and calibrated using appropriate 
carriers or surrogates. 
Ground Application: Apply this product at the appropriate rate as specified on this label in 3 to 10 gallons of 
water per acre as a broadcast spray. For optimum spray distribution and coverage, use flat fan or low-volume 
flood nozzles. When using flood nozzles, space them no more than 40 inches apart and ensure double 
overlap of spray pattern. Refer to the manufacturer's recommendations for correct pressure and nozzle 
height above the target canopy. Avoid pressure and nozzles that produce fine droplets or mist. Apply using a 
nozzle height of no more than 4 feet above the ground or crop canopy. 
Use appropriate marking devices to ensure uniform spray coverage and best results from Landmaster II 
herbicide. 
Hand-Held and High-Volume Equipment: (use coarse sprays only): Mix this product in clean water and 
apply to foliage of vegetation to be controlled. For application made on a spray-to-wet basis, spray coverage 
should be uniform and complete. Do not spray to the point of runoff. Use a 1-percent solution for field 
bindweed. 
Aerial Application: Apply this product at the appropriate rate as specified on this label in 3 to 5 gallons of 
water per acre. 
The boom length must not exceed 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 
with a cross-wind, the swath will be displaced downwind. The applicator must compensate for this 
displacement at the downwind side.

( 
CLEAN THE ENTIRE SPRAYER AFTER APPLICATION OF THIS PRODUCT. Failure to clean the sprayer 
thoroughly may result in injury to desirable crops that are subsequently sprayed with equipment used to apply 
this product. First, add clean water to the tank and thoroughly rinse the entire sprayer system. Second, fill the 
tank with clean water and 1 quart of household ammonia for every 25 gallons of water. Pump enough of this 
solution through the hoses, boom and nozzles to fill these parts completely. Refill the tank, close and leave 
for 24 hours before draining and rinsing thoroughly with clean water. 
Application or use of other agricultural chemicals with the equipment used for this product may result in injury 
to desirable vegetation. 
Thoroughly wash aircraft, especially landing gear, after each day of spraying to remove residues of this 
product accumulated during spraying or from spills. PROLONGED EXPOSURE OF THIS PRODUCT TO 
UNCOATED STEEL SURFACES MAY RESULT IN CORROSION AND POSSIBLE FAILURE OF THE 
PART. LANDING GEAR ARE MOST SUSCEPTIBLE. The maintenance of an organic coating (paint) which 
meets aerospace specification MIL-C-38413 may prevent corrosion. 
Application Instructions 
Timing of Application 
Apply this product postemergence to vigorously growing weeds when they have reached the size given in the 
"APPLICATION RATES AND WEEDS CONTROLLED" section of this label. Application should be delayed 
until maximum emergence of the target weeds, but before weeds exceed the maximum size indicated. For 
annual weeds, allow 1 day after treatment before tillage. For field bindweed, allow at least 7 days after 
treatment before tillage. 
Reduced control may result if treatment is made under poor growing conditions such as drought stress, 
disease or insect damage, or if weeds have been mowed, grazed or cut. Heavy dust on foliage or an 
overstory canopy covering targeted weeds can also reduce control. 
Rainfall or irrigation occurring within 6 hours after application can reduce effectiveness. Heavy rainfall or 
irrigation within 2 hours after application will wash this product off the foliage and a repeat treatment may be 
required. 
For field bindweed and quackgrass, do not till between harvest and fall application, or in fall or spring prior to 
spring application. 
Application Rates and Weeds Controlled Using Landmaster II Alone 
For best results, apply this product after most weed seeds have germinated but before seed head formation in 
grasses or flower bud formation in broadleaves. 
When applied as directed, this product will provide control or suppression of the grass and broad leaf weed 
species listed below. Application rates are for maximum weed height at treatment time.
