Product Information 
 
Weed Rhap LV-4 herbicide is intended for selective control of many broadleaf weeds in certain crops, 
including, cereal grains (wheat, barley, millet, oats and rye), corn (field corn, popcorn and sweet corn), 
fallow land and crop stubble, sorghum (grain and forage sorghum), and soybeans (preplant burndown 
application only), forests, rangeland and established grass pastures including Conservation Reserve 
Program (CRP) acres, non-cropland, grasses grown for seed or sod, and ornamental turfgrass. 
 
Apply Weed Rhap LV-4 as a water or oil-water spray during warm weather when weeds or woody plants 
are actively growing. Application under drought conditions will often give poor results. Use low spray 
pressure to minimize drift. Generally, the lower dosages specified on this label are satisfactory for young, 
succulent growth of susceptible weed species. For less susceptible species and under conditions where 
control is more difficult, use higher specified rates. Deep-rooted perennial weeds, such as Canada thistle 
and field bindweed and many woody plants, usually require repeated applications for satisfactory control.

Use Precautions and Restrictions 
 
Chemigation: Do not apply this product through any type of irrigation system. 
 
Excessive amounts of 2,4-D in the soil may temporarily inhibit seed germination and plant growth. 
 
Use of this product in certain portions of California, Oregon and Washington is subject to the January 22, 
2004 Order for injunctive relief in Washington Toxics Coalition, et al. v. EPA, C01-0132C, (W.D. WA). 
For further information, please refer to EPA Web site: http://www.epa.gov/espp. 
 
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, 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 
contain 2,4-D mixed with active ingredients that require a coarse or coarser spray, apply only as a coarse 
or coarser spray (ASABE Standard 572) or a volume mean diameter of 385 microns or more 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 (ASABE Standard 572) or a volume mean 
diameter of 300 microns or more for spinning atomizer nozzles. 
 
Wind Speed 
Do not apply at wind speeds more than 15 mph. Apply this product only if the wind direction favors on-
target deposition and there are not sensitive areas (including 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 mph, the applicator must determine if: a) conditions of temperature 
inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not make 
applications 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 cotton, okra, flowers, fruit trees, 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 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 and ground application equipment must be properly maintained and calibrated using appropriate 
carriers or surrogates.

Weed Rhap LV-4 (5905-ANN) 100316(2) CLN.doc 
 
 
Aerial Application 
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 crosswind, the swath will be displaced downwind. The applicator 
must compensate for this by adjusting the path of the aircraft upwind. 
 
Ground Boom Application 
Do not apply with a nozzle height greater than 4 feet above the crop canopy. 
 
2,4-D esters may volatilize during conditions of low humidity and high temperatures. Do not apply during 
conditions of low humidity and high temperatures. 
 
Mixing Directions 
 
1. Fill the spray tank about half full with water, then add the required amount of Weed Rhap LV-4 with 
agitation, and finally the rest of the water. Note: Weed Rhap LV-4 in water forms an emulsion that 
tends to separate unless the mixture is kept agitated. 
2. If oil is added, first mix the Weed Rhap LV-4 and the oil and then add this mixture to the water. 
However, with adequate agitation, the oil can be added after Weed Rhap LV-4 is mixed with water. 
3. If straight oil is used, a solution is formed and separation does not occur. Do not allow any water to 
get into the oil-herbicide mixture to avoid formation of an invert emulsion. 
 
Note: Adding oil, wetting agent, or other surfactant to the spray mixture may increase effectiveness on 
weeds, but also may reduce selectivity in crops resulting in crop damage. 
 
Tank Mixing Precautions: 
x Read carefully and follow all applicable use directions, precautions, and limitations on the respective 
product labels. 
x Do not exceed specified application rates. Do not tank mix with another pesticide product that contains 
the same active ingredient as this product unless the label of either tank mix partner specifies the 
maximum dosages that may be used. 
 
Tank Mix Compatibility Testing: A jar test is recommended prior to tank mixing to ensure compatibility 
of this product and other pesticides. Use a clear glass quart jar with lid and mix the tank mix ingredients 
in their relative proportions. Invert the jar containing the mixture several times and observe the mixture 
for approximately 1/2 hour. If the mixture balls-up, forms flakes, sludges, jels, oily films or layers, or other 
precipitates, it is not compatible and the tank mix combination should not be used. 
 
Mixing with Liquid Nitrogen Fertilizer 
This product may be combined with liquid nitrogen fertilizer suitable for foliar application to accomplish 
broadleaf weed control and fertilization of corn, small grains or pastures in a single operation. Use Weed 
Rhap LV-4 in accordance with directions for these crops provided in this label. Use liquid fertilizer at 
rates specified by the supplier or Extension Service Specialist. Test for mixing compatibility by mixing 
spray ingredients in correct proportions in a clear glass jar before mixing in spray tank. A compatibility 
aid such as Unite or Compex may be needed in some situations. Compatibility is best with liquid fertilizer 
solutions containing only nitrogen. Mixing with N-P-K solutions may not be satisfactory, even with the 
addition of a compatibility aid. Pre-mixing Weed Rhap LV-4 with 1 to 4 parts water may help in situations 
when mixing difficulty occurs. 
 
5

Weed Rhap LV-4 (5905-ANN) 100316(2) CLN.doc 
Fill the tank about half full with the liquid fertilizer, then add the required amount of Weed Rhap LV-4 with 
agitation. Maintain agitation and complete filling the tank with liquid fertilizer. Apply immediately and 
continue agitation in spray tank during application. Do not store the spray mixture. Application during 
very cold weather (near freezing) is not advisable. 
 
Sprayer Equipment Clean-Out 
To avoid injury to desirable plants, thoroughly clean equipment used to apply this product before re-use 
or applying other chemicals. 
 
1. Rinse and flush application equipment thoroughly after use at least three times with water. Dispose 
of all rinse water by application to treatment area or apply to non-cropland area away from water 
supplies. 
2. During the second rinse, add 1 quart of household ammonia for every 25 gallons of water. Circulate 
the solution through the entire system so that all internal surfaces are contacted (15 to 20 minutes). 
Let the solution stand for several hours, preferably overnight. 
3. Flush the solution out of the spray tank through the boom. 
4. Rinse the system twice with clean water, recirculating and draining each time. 
5. Remove nozzles and screens and clean separately. 
6. If equipment is to be used to apply another pesticide or agricultural chemical to a 2,4-D susceptible 
crop, additional steps may be required to remove all traces of 2,4-D, including cleaning of 
disassembled parts and replacement of hoses or other fittings that may contain absorbed 2,4-D. 
 
Application Directions 
 
Spray Volume 
Apply with calibrated air or ground equipment using sufficient spray volume to provide adequate coverage 
of target weeds or as otherwise directed in specific use directions. For broadcast application, apply the 
specified rate of this product in a spray volume of 2 gallons or more per acre by air and 10 gallons or 
more per acre for ground equipment. Use low-pressure sprays to minimize drift. Where states have 
regulations that specify minimum spray volumes, they must be observed. In general, increase spray 
volume as crop canopy, height and weed density increase in order to obtain adequate spray coverage. 
Do not apply less than 2 gallons total spray volume per acre. 
 
Application Rates 
Generally, lower rates in specified rate ranges are satisfactory for more sensitive weeds species, when 
weeds are small, and when environmental conditions are favorable for rapid growth. Use higher rates in 
the specified rate range for less sensitive species and under less favorable growing conditions. For crop 
uses, do not mix with oil or other adjuvants unless specifically directed to do so on this label. Deep-
rooted perennial weeds, such as Canada thistle and field bindweed and many woody plants, usually 
require repeated applications for effective control. 
 
Spot Treatments 
To prevent misapplication, apply spot treatments with a calibrated boom or with hand sprayer using a 
fixed spray volume per 1000 sq ft as indicated below. 
 
Hand-Held Sprayers: Hand-held sprayers may be used for spot applications of Weed Rhap LV-4 in 
labeled crops. Take care to apply the spray uniformly and at a rate equivalent to a broadcast application. 
Application rates in the table are based upon a treatment area of 1000 sq ft. Mix the amount of Weed 
Rhap LV-4 (fl oz or mLl) corresponding to the desired broadcast rate in 1 gallon or more of spray. To 
calculate the amount of Weed Rhap LV-4 required for larger areas, multiply the table value (fl oz or mL) 
by the number of thousands of sq ft of area to be treated. An area of 1000 sq ft is approximately 10.5 X 
10.5 yards (strides) in size.

preharvest application (all 
cereals)
1 Apply using air or ground equipment to control 
weeds that could interfere with harvest, or to 
suppress perennial weeds. Apply when grain is in 
dough stage. Do not apply from early boot 
through the milk stage of growth. 
1Use the lower rate in the rate range if small annual or biennial weeds are the major problem. Use the 
higher rate if perennial weeds or annual or biennial weeds are present which are considered to be hard 
to kill as determined by local experience. Up to 2.5 pints per acre may be applied postemergence to 
wheat, barley, rye and millet. However, there is greater risk of crop injury at rates greater than 1 1/3 
pints per acre and such rates should be used only when the need for weed control justifies additional 
risk to the crop. Do not apply Weed Rhap LV-4 at the crop seedling stage of growth. Consult state 
agricultural experiment station or extension service weed specialists for recommendations or

(pt/acre)
Specific Use Directions 
preplant (burndown) 
preemergence
 field corn, popcorn, sweet 
corn
1 - 2 General: For best results, growth conditions should 
be favorable for active weed growth. Use high rate 
in rate range for less susceptible weeds, cover 
crops such as alfalfa, weeds in advanced stages of 
development, or under less favorable growth 
conditions. 
Preplant: Apply 7 to 14 days before planting corn to 
control emerged broadleaf weed seedlings or 
existing cover crops. 
Preemergence: Apply any time after planting, but 
before corn emerges to control broadleaf weed 
seedlings or existing cover crops. Do not use on 
light sandy soils. 
postemergence 
field corn, popcorn, sweet corn 
annual broadleaf weeds 
Apply when weeds are small and corn is less than 8 
inches tall (to top of canopy). If corn is more than 8 
inches tall, use drop nozzles to keep spray off of 
foliage. 
Treat perennial weeds when they are in bud to 
bloom stage. 
Do not tank mix with atrazine, oil or other adjuvants. 
Do not apply from tasseling to hard dough stage. 
Note: Corn treated with 2,4-D may become 
temporarily brittle. Wind or cultivation may cause 
stem breakage during the period of time that corn is 
brittle. 
Sweet Corn: To minimize potential for crop injury, 
use only lowest rate in rate range.

Restrictions:
• Preharvest Interval: Do not apply within 7 days before cutting forage or hay from treated areas. 
• Do not apply more than 4 pints of Weed Rhap LV-4 (2.0 lb acid equivalent) per acre per application. 
• Do not apply more than 8 pints of Weed Rhap LV-4 (4.0 lb acid equivalent) per acre per year. 
• Do not re-apply within 30 days of a previous application. 
• Do not make more than two applications per season. 
 
Planting in Treated Areas 
Labeled Crops: Within 29 days after an application of this product, plant only those crops listed on this or 
other registered 2,4-D labels. Follow more specific limitations, if any, provided in directions for specific 
crops. Labeled crops may be at risk of crop injury or loss if planted soon after application, especially 
during the first 14 days. Consider degradation factors described below in weighing this risk. 
 
Other Crops: All other crops may be planted 30 days or more after application without concern for illegal 
residues in the planted crop. However, under certain conditions, there may be a risk of injury to 
susceptible crops. Consider degradation factors described below in weighing this risk. Under average 
conditions, any crop may be planted without risk of injury if at least 90 days of soil temperatures above 
freezing have elapsed since application. 
 
Degradation Factors: When planting into treated areas, the risk of crop injury is less if lower rates of 
product were applied and conditions following application have included warm, moist soil conditions that 
favor rapid breakdown of 2,4-D. Risk is greater if higher rates of product were applied and soil 
temperatures have been cold and/or soils have been excessively wet or dry in the days following 
application. Consult your local agricultural extension service for information about susceptible crops and 
typical conditions in your area.

(Not for Use in California) 
 
Application Timing 
Weed Rhap LV-
4
(pt/acre)
Specific Use Directions 
preplant (burndown) 3/4 - 1 Apply not less than 7 days before planting soybeans. 
See Precautions and Restrictions below. 
1 - 2 Apply not less than 15 days before planting soybeans. 
See Precautions and Restrictions below. 
General: Use Weed Rhap LV-4 to control emerged broadleaf weeds or existing cover crops. For best 
results, apply when weeds are small and actively growing. Use the higher rate in the rate range for 
larger weeds and when perennials are present. Compatible crop oil concentrates, agricultural 
surfactants and fluid fertilizers approved for use on growing crops may be added to spray mixtures to 
increase the herbicidal effectiveness on certain weeds. Read and follow all directions and precautions 
on this label and on the label of each product added to the spray mixture. 
 
Precautions:
• Important Notice: Unacceptable injury to soybeans planted in treated fields may occur. Whether 
soybean injury occurs and the extent of such injury will depend upon weather (temperature and rainfall) 
from herbicide application until soybean emergence and agronomic factors, such as the amount of 
weed vegetation and previous crop residue present at the time of application. Injury is more likely 
under cool rainy conditions and where there is less weed vegetation and crop residue present. 
• In treated fields, plant soybean seed as deep as practical, but not less than 1 inch deep. Adjust the 
planter, if necessary, to ensure that planted seed is adequately covered. 
 
Restrictions: 
• Do not disturb treated soil through tillage between application and planting of soybeans.
• Do not use on sandy soils with less than 1% organic matter. 
• Do not make more than one application per season regardless of the application rate used. 
• Do not apply Weed Rhap LV-4 as a preplant application in soybeans unless you are prepared to 
accept the results of soybean injury, including possible stand loss and/or yield reduction. 
• During the growing season following application, do not replant treated fields with crops other than 
those labeled for use with Weed Rhap LV-4. 
• Do not apply more than 2 pints of Weed Rhap LV-4 (1.0 lb acid equivalent) per acre per year.
