FARMSTEAD FENCEROW TREATMENT
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.
Farmstead and Fence-row Treatment Application Instructions
HM-0335A may be applied using water or oil and water emulsions in spot application to control undesirable vegetation using handgun or similar types of application equipment. In addition to weed species listed in Tables 1 and 2, these treatments may be used to control or suppress woody plant species listed in Table 7.
To prepare soil and water emulsions, mix in the order and proportions indicated below.
The solution should remain milky colored without an oily layer on top when under agitation. If an oily layer forms, increase the amount of emulsifier or change to a more effective emulsifier.
Do not exceed 40 gallons of spray solution per treated acre per application. 4 ¾ pints of HM-0335A in forty gallons of spray solution contains 1.1 pounds acid equivalent of dicamba and 1.4 pounds acid equivalent of 2,4-D.
Spray plants to wet. Do not allow this spray mix to contact desirable vegetation.
To control brush, briars, and weeds along fence-rows surrounding pasture and ranch lands, and fallow fields, use a tank-mix of 1.5% HM-0335A, 88.5% water, 10% diesel oil, and sufficient emulsifier (to mix the diesel and emulsifier). The diesel oil in this tank-mix will damage or kill desirable grasses and should not be used in pastures or where damage to desirable species cannot be tolerated.
FOR SPRAYING FOLIAR APPLICATIONS:
1. Spray when leaves have reached full size but have not hardened due to drought or maturity.
2. Spray individual plants to wet with handgun.
3. For larger stems (up to 3\" in diameter) and hard to control species, direct spray stream to base of stems to wet the stem at soil surface in addition to wetting the foliage.
4. Do not apply under drip line of desirable trees or adjacent to desirable vegetation.
FOR DORMANT BASAL APPLICATIONS:
1. Increase diesel oil content to 15% or 15 gallons of diesel oil per 100 gallons of total solution.
2. Spray in late winter and early spring before plants break dormancy.
3. Spray the bottom 24\" of the target stem to wet on all sides.
4. For larger stems (up to 3\" in diameter) and hard to kill species direct the spray solution to the base of target stems to wet the soil at the stem/soil junction in addition to wetting the stem.
5. Do not apply under drip line of desirable trees or adjacent to desirable vegetation.
FOR CUT SURFACE TREATMENTS:
Apply HM-0335A in an undiluted state as a cut surface treatment to control unwanted trees and prevent sprouts of cut trees.
- Frill or Girdle Treatments: Make a continuous cut or a series of overlapping cuts using an axe to girdle tree trunk. Spray or paint the cut surface with HM-0335A.
Stump Treatments: Spray or paint freshly cut surface with HM-0335A. The cambium layer (the area adjacent to the bark) should be thoroughly wet. Treat stumps within 6 hours after cutting. Table 7. The following list of trees and vines can be controlled on farmsteads and fencerows as foliar, basal, or cut surface treatments
