APPLICATIONS TO FALLOW GROUND PRIOR TO PLANTING COTTON
HM-0335A is a postemergence herbicide for controlling a wide spectrum of annual, biennial, and perennial broadleaf weeds and brush in pastures, rangeland, and grass (hay, silage); sugarcane; wheat; conservation reserve program land; postharvest, fallow, crop stubble, set-aside acres; general farmstead areas; and certain noncrop areas.
Use of this product in certain portions of California, Oregon, and Washington is subject to the January 22, 2004 Order of Injunctive Relief in Washington Toxics Coalition et all vs. EPA CO1-132C (W.D.WA.). For information, please refer to www.epa.gov/espp/wtc/.
Mode of Action
HM-0335A contains two active ingredients uniquely formulated to be used alone or tank-mixed with other listed products as well as liquid fertilizer solutions. HM-0335A is readily absorbed by plants through shoot and root uptake, translocates throughout the plant’s system, and accumulates in areas of active growth. HM-0335A interferes with the plant’s growth hormones (auxins) resulting in death of many broadleaf weeds.
For best results, thoroughly clean sprayer equipment (tank, lines and nozzles) immediately after use by flushing system with water and heavy duty detergent or other suitable tank cleaner.
Apply HM-0335A 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 Information.” HM-0335A may be applied using water or sprayable fluid fertilizer as a carrier. Sprayable fluid fertilizer may be used as the carrier in preplant or pre-emergence use for all crops listed on the label. Postemergence uses with sprayable fluid fertilizer may be made on pasture, hayland, or wheat crops only. The 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 determined by the weed species requiring the highest rate. Delaying application permits weeds to exceed the maximum size and will prevent adequate control. For certain specified applications liquid fertilizer or oil may replace part or all of the water as diluent. If dry flowable (DF), wettable powder (WP) or flowable (F) tank-mix products are to be used, these should generally be added to the spray tank first. Refer to the mixing directions on the labels of the tank-mix products.
In irrigated areas, it may be necessary to irrigate before treatment to ensure active weed growth.
AERIAL APPLICATION METHODS AND EQUIPMENT
Water Volume: Use 3-10 gallons of water per acre. Use the higher 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 the exposure of spray droplets to evaporation and wind. The applicator must follow the most restrictive use cautions to avoid drift hazards, including those found in the labeling as well as applicable state and local regulations and ordinances.
Ground Application (Banding)
When applying HM-0335A herbicide by banding, determine the amount of herbicide and water volume needed using the following formula.
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 of fine spray particles. Spray nozzles as close to the weeds as is practical for good weed coverage.
Spot or Small Area Application
HM-0335A 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 other small capacity sprayers, prepare a solution of HM-0335A in water according to Table 3 (assuming that the spot treatment rate equates to 40 gallons pre acre on the broadcast basis.) Adding a surfactant (0.5% by volume) can help improve control.
Do not make spot treatments in addition to broadcast or band treatments.
Application equipment: Select nozzles designed to produce minimal amounts of fine spray particles. Spray with nozzles as close to the weeds as is practical for good weed coverage.
Apply HM-0335A as a broadcast or spot treatment to emerged and actively-growing weeds. The most effective control of weeds occurs if application is made when weeds are in the 2-4 leaf stage and rosettes are less than 2\" across.
