APPLICATION INSTRUCTIONS:
Irrigated Areas:
Applying Avalanche Ultra to weed species under conditions of drought may result in inadequate control. In order to ensure weeds are actively growing, it may be necessary to irrigate target areas prior to applying this product.
Spray Coverage:
For effective control and thorough coverage, ensure this product is applied in a sufficient spray volume. Spray coverage may be prevented or hindered by dense leaf canopies that may shelter smaller target weeds.
Treat with Avalanche Ultra as an aerial banding application or as a broadcast application to actively growing weeds.
Adequate control may be hindered if treatment with Avalanche Ultra is delayed as the growth stage specified in this label may be exceeded. Applying Avalanche Ultra during early postemergence when weeds are small will allow treatment using the lower rate (dependent upon the weed species present) and will facilitate thorough spray coverage.
Aerial Application:
Use a minimum of 10 gallons per acre of water when applying this product as an aerial application. A minimum of 5 gallons per acre of water has been effective where sufficient coverage can be achieved.
Application Equipment
Use spray equipment for applications of Avalanche Ultra at a pressure of up to 40 psi. Applicators must use diaphragm-type nozzles that create cone patterns or fan spray. In order to avoid drift and to ensure best coverage with Avalanche Ultra, refer to the Spray Drift Management section on the label.
Ground (Banding) Applications:
Adjust row banding equipment n order to ensure the most thorough coverage of weeds in the row. Direct two nozzles from either side of the crop row toward the target weeds in the center rows. Do not use a single nozzle for treatment over the row. Use a minimum of 15 gallons of water per acre on the band with a minimum band width of 15 inches. For further instructions, refer to the Ground Application Equipment and Methods of Application (Broadcast) section.
Ground Application Equipment and Methods of Application (Broadcast):
Application Equipment
Use hollow cone nozzles to apply Avalanche Ultra, spaced 20 inches apart (maximum). Application may also be made with a standard high-pressure flat fan for pesticide treatment. Do not apply this product with flood, controlled droplet applicator (CDA) or chamber nozzles as inconsistent coverage may result, causing variable weed control. Do not apply Avalanche Ultra with selective application equipment such as wiper applicators or recirculating sprayers.
ADDITIONAL WEED PROBLEMS IN PEANUTS AND SOYBEANS
SPECIAL USE DIRECTIONS:
Prior to applying Avalanche Ultra with spray equipment, ensure that there is good soil moisture. For an effective application, soil must be moist before and after application.
Use a rate of 1.5 pints of Avalanche Ultra per acre, mixed with 2 pints of spray surfactant per 100 gallons of spray mix (unless otherwise stated) for the following weeds:
Beggarweed, Florida
Florida Beggarweed is difficult to control because it has a long germination season. Apply Avalanche Ultra when Florida Beggarweed seedlings have no more than 2 expanding young true leaves and seedlings are no higher than 1.5 inches.
To ensure optimal treatment of Avalanche Ultra for control of Florida Beggarweed, obtain maximum control of the earliest flush of the weed. Schedule cultivation to ensure that secondary weed flushes and regrowth are controlled.
Applications of Avalanche Ultra will suppress and/or partially control Florida Beggarweed growing in high soil moisture or in high relative humidity.
Buffalobur, Wild Buckwheat
Avalanche Ultra will provide partial control when buffalobur and wild buckwheat seedlings have less than 2 true leaves. Treat with Avalanche Ultra at a rate of 1.5 pints per acre in 30 gallons of water.
SEE LABEL FOR COMPLETE RATES AND INSTRUCTIONS.
RESTRICTIONS:
Soybeans and peanuts:
Strawberries
Rice
LIMITATIONS:
The effectiveness of an application of this product may be reduced if rainfall or overhead irrigation happens within 4 hours of treatment.
ENVIRONMENTAL HAZARDS:
Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark, except as specified on this label for application to rice. Do not contaminate water when disposing of equipment washwaters. Do not apply when weather conditions favor drift from target area.
