GENERAL INFORMATION

DuPont™ VELPAR® L herbicide is a water-dispersible

iquid that is mixed in water and applied as a spray for weed

l control in certain crops, Christmas trees, forestry site preparation and release areas, and industrial areas. It may also be applied undiluted as a basal soil treatment for brush control in reforestation areas, rangeland, pastures and noncrop areas, or by stem injection for brush control.

VELPAR® L is an effective general herbicide providing both contact and residual control of many annual, biennial and perennial weeds and woody plants.

VELPAR® L is noncorrosive to equipment.

Care should be exercised when applying VELPAR® L near desirable trees or shrubs as they can absorb VELPAR® L through roots extending into treated areas.

This product may be applied on conifer plantations and noncrop sites that contain areas of temporary surface water caused by collection of water between planting beds, in equipment ruts, or in other depressions created by management activities. It is permissible to treat intermittent drainage, intermittently flooded low lying sites, seasonally dry flood plains and transitional areas between upland and lowland sites when no water is present. It is also permissible to treat marshes, swamps and bogs after water has receded, as well as seasonally dry flood deltas. DO NOT make applications to natural or man-made bodies of water such as lakes, reservoirs, ponds, streams and canals.

ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY

VELPAR® L is absorbed through the roots and foliage. Moisture is required to activate VELPAR® L in the soil. Best results are obtained when the soil is moist at the time of application and 1/4–1/2 inches of rainfall occurs within 2 weeks after application.

For best results, apply VELPAR® L preemergence or postemergence when weeds are less than 2 inches in height or diameter. Foliar activity is most effective under conditions of

ture (above 80 °F), high humidity, and good soil

high temper moisture dormant, semi-dormant, or under stress.

On herbaceous plants, after application under warm, humid conditions, while 4–6 weeks may be required when weather is cool or dry, or when plants ar to activate VELPAR® L in the soil, plants may recover from contact effects and continue to grow.

On woody plants, symptoms usually appear within 3–6 weeks after sufficient rainfall has carried the herbicide into the root zone during periods of active growth. Defoliation and refoliation may occur, but susceptible plants are killed.

The degree and duration of control may depend on the following:

• Use rate

• Weed spectrum and size at application

• Environmental conditions a

Where a rate range is shown, use the higher levels of the dosage range on hard-to-control species, fine-textured soils, or soils

ontaining greater than 5% organic matter or carbon. Use the

c lower levels of the dosage range on coarse-textured soils and/or

n soils low in organic matter. Refer to specific uses for rate

o ranges.

APPLICATION INFORMATION

VELPAR® L may be applied by ground equipment and, where permitted, aerial equipment. Use rates, minimum spray gallonage, and other application information are described for the various uses.

Dispose of the equipment washwater by applying it to a usesite listed on this label or in accordance with directions given in the “Storage and Disposal” section of this label.

Before spraying, calibrate equipment to determine the quantity of water necessary to uniformly and thoroughly cover the vegetation and soil in a measured area to be treated.

TANK MIXTURES

VELPAR® L herbicide may be tank mixed with other herbicides and /or adjuvants registered for the uses (crops) specified in the label.

Refer to the label of the tank mix partner(s) for any additional use instructions or restrictions.

NOTE: When the air temperature is around 32oF, tank mixtures of “Gramoxone Max” (paraquat dichloride) plus VELPAR® L may form a hard sludge in the spray tank. This effect is most likely to occur when the tank mixture comes into contact with aluminum.

RESISTANCE

When herbicides that affect the same biological site of action are used repeatedly over several years to control the same weed species in the same field, naturally-occurring resistant biotypes may survive a correctly applied herbicide tr

eatment, propagate, and become dominant in that field. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different site of action.

o better mana

T proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that have a different site of action.

CHEMIGATION ALFALFA

pply this product only through center pivot sprinkler

A irrigation systems. Do not apply this product through any other type of irrigation system. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniform distribution of treated water. Severe alfalfa injury may result following application after cutting if either the regrowth is more than 2” high or significant stubble is left after alfalfa cutting. If you have questions about calibration, you should contact State Extension Service specialists, equipment manufacturers or other experts. A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise.

DORMANT

Select the appropriate rate, see Use Rate section, for soil texture and organic matter content using 0.25” to 0.75” of sprinkler irrigation as a continuous injection during the application. Best results are obtained when soil is moist at time of application, and when weeds have not germinated or are less than 2” tall or across.

APPLICATION AFTER CUTTING

Apply VELPAR® L at 1 pint per acre to stubble after cutting, following hay removal, and before regrowth exceeds 2” in height. Apply VELPAR® L using 0.25” to

0.75” of sprinkler irrigation as a continuous injection during the application. Best results are obtained when soil is moist at time of application and when weeds have not germinated or are less than 2” tall or across. NOTE: Making an application when daily temperatures are forecast to be in the mid-to-high 90 degree temperature range within 3 to 5 days after treatment may increase the potential for crop injury.

SPRINKLER CHEMIGATION

The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump.

IXING INSTRUCTIONS

1. Fill the supply tank 1/4 to 1/3 full of water.

2. While agitating, add the required amount of VELPAR® L and continue agitation.

3. Once the VELPAR® L is fully dispersed, maintain agitation and continue filling tank with water.

4. As the tank is filling, add tank mix partners (if desired). Follow use precautions and directions on the tank mix partner label.

5. After thorough mixing, the agitation system can be stopped to prevent excessive foaming in the tank. Once thoroughly mixed the solution in the supply tank does not require additional agitation unless specified on the companion products label. If foaming occurs in the injection supply tank, a defoaming agent (defoamer) may be added.

6. Apply VELPAR® L spray mixture within 48 hours of mixing to avoid product degradation.

USE PRECAUTIONS CHEMIGATION

•

Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the pesticide label prescribed safety devices for public water systems are in place.

•

Distributing treated water in an uneven manner can result in crop injury, lack of effectiveness, or over-tolerance pesticide residues in the crop. Therefore, to ensure that the mixture is applied evenly at the recommended rate, use sufficient water, apply the mixture for the proper length of time and ensure sprinkler produces a uniform water pattern.

•

Do not permit run-off during chemigation.

POSTING OF AREAS TO BE TREATED

Posting of areas to be chemigated is required when 1) any part of a treated area is within 300 feet of sensitive areas such as residential areas, labor camps, businesses, daycare centers, hospitals, in-patient clinics, nursing homes, or any public areas such as schools, parks, playgrounds, or other public facilities not including public roads, or 2) when the

• Posting required for chemigation does not replace other

posting and reentry requirements for farm worker safety.

REPLANTING (FOLLOWING ALFALFA)

• Do not replant treated areas to any crop except corn, root

crops or sugarcane within two years after treatment, as crop

y may result.

injur

• Corn may be planted 12 months after the last treatment in

areas of moderate to high rainfall (greater than 20 inches), provided the use rate did not exceed 3 pints per acre.

• Root crops such as potatoes, sugarbeets, radish and carrots

may be planted 12 months after last treatment, provided the use rate does not exceed 2 pints per acre. Sites with use rates higher than 2 pints per acre should not be replanted to any root crop within 2 years after application of VELPAR® L, or unacceptable crop injury may result.

In areas where irrigation is needed to produce the crop, the crop rotation intervals listed may need to be extended if the normal irrigation amount is reduced for any reason.

• Sugarcane may be planted any time following treatment.

• In California, do not replant seed alfalfa areas to any crop

within two years after treatment, as crop injury may result.

DuPont™

FLOOD IRRIGATED ALFALFA

In arid climates (10 inches of rainfall or less per year) or areas where drought conditions have prevailed for one or more years, a field bioassay should be completed prior to planting

ny desired crop. The results of this bioassay may require the

a rotation intervals listed above to be extended.

A successful bioassay means growing to maturity a test strip of the crop(s) intended for production. The test crop(s) strip should cross the entire field including knolls, low areas, and areas where any berms were located.

In areas where irrigation is needed to produce the crop, the crop rotation intervals listed may need to be extended if the normal irrigation amount is reduced for any reason.

ALFALFA - IMPREGNATION ON DRY BULK FERTILIZER

(EXCEPT

CALIFORNIA AND ARIZONA)

Dry bulk fertilizer may be impregnated or coated with VELPAR® L for application to established alfalfa. All recommendations and precautions on this label must be followed along with state regulations relating to dry bulk fertilizer blending, impregnating and labeling.

If fertilizer materials are excessively dusty, use a suitable additive to reduce dust prior to impregnation, as dusty fertilizer will result in poor distribution during application. The dry fertilizer must be properly impregnated and uniformly applied to the alfalfa to avoid crop injury and/or poor weed control.

To impregnate the fertilizer, use a system consisting of a conveyor or closed drum used to blend dry bulk fertilizer. Any commonly used fertilizer can be impregnated with VELPAR® L, except potassium nitrate or sodium nitrate. Do not use VELPAR® L on limestone.

Use a minimum of 250 lb dry bulk fertilizer per acre and up to a maximum of 450 lb per acre. To impregnate or coat the dry bulk fertilizer with VELPAR® L, direct the nozzles to deliver a fine spray of this suspension toward the fertilizer for thorough coverage while avoiding spray contact with mixing equipment. Uniform impregnation of VELPAR® L to dry bulk fertilizer will vary, and if the absorptivity is not adequate, the use of an absorptive powder may be required to produce a dry, free-flowing mixture. “Microcel E” is the recommended absorbent powder. When another herbicide is used with VELPAR® L, mix and impregnate the fertilizer immediately.

Apply impregnated fertilizer as soon as possible after impregna

tion for optimum performance.

Select the rate of VELPAR® L to apply per acre from the appropriate section of this label. Then refer to the rate chart below to determine the amount of VELPAR® L that should be impregnated on a ton of dry bulk fertilizer, based on the amount of f

tiliz

er to be distr

ibuted in one acre

APPLICATION

Uniform application of VELPAR® L-impregnated dry fertilizer is essential for satisfactory weed control. Accurate calibration of the application equipment is essential for uniform distribution to the surface. The recommended method of application is to apply 1/2 the recommended rate and overlap 50%. This results in the best distribution pattern.

USE PRECAUTIONS - ALFALFA

• Best results are obtained when 1/2–1 inch of rainfall or

sprinkler irrigation occurs within two weeks after application, when soil is moist at time of application, and when weeds have not germinated or are less than 2 inches in height or diameter. Heavy rainfall or excessive irrigation after application may result in crop injury or poor performance of the herbicide.

On soils high in organic matter (greater than 5%), the
