WOODY PLANT CONTROL
PastureGard herbicide, an oil soluble, emulsifiable liquid product containing triclopyr and fluroxypyr herbicides, is recommended for the control of unwanted broadleaf herbaceous and woody plants in rangeland and permanent pastures, CRP acres, fence rows, and in non-crop areas including non-irrigation ditch banks and around farm buildings. Individual plant treatments may be made using broadcast, foliar, basal bark, or cut stump application techniques. Broadcast or directed foliar spray treatments must be made to plants that are in full leaf at the time of application. PastureGard controls only broadleaf plants that are emerged at the time of application.
Use Precautions and Restrictions
- The combination of PastureGard with any other product containing fluroxypyr or triclopyr cannot exceed the maximum of 0.5 lb a.e. fluroxypyr or 2.0 lb a.e. triclopyr per acre per annual growing season.
- The state of Arizona has not approved this product for use on plants grown for agricultural/commercial production; specifically on designated grazing areas.
- Do not use on bentgrass, alfalfa, or other desirable forbs, especially legumes such as clover, unless injury or loss of such plants can be tolerated.
- Do not apply directly to the banks of ditches used for irrigation or domestic purposes. Do not apply directly to water (see Environmental Hazards section).
- Chemigation: Do not apply this product through any type of irrigation system.
- PastureGard is formulated as a low-volatile ester. However, the combination of spray contact with impervious surfaces, such as roads and rocks, and increasing ambient air temperatures, may result in an increase in the volatility potential for this herbicide, increasing a risk for off-target injury to sensitive crops such as grapes and tomatoes.
- Where oil is recomended as a diluent in the label, only use oil approved for food or feed production when applications are made to pasture and rangeland, including areas harvested for feed. Applications made directly to cut stumps or basal bark may use diesel, kerosene or a commercial basal carrier.
- Not for sale, distribution, or use in Nassau and Suffolk counties in New York State
Grass, Forage and Tree Tolerance
- Established grasses are tolerant to this product.
- Maximum Application Rate: Do not apply more than 0.5 lb a.e. fluroxypyr or 1.5 lb a.e. triclopyr (4 quarts per acre of PastureGard) per annual growing season.
- Do not use on alfalfa, or other desirable forbs, especially legumes such as clover, unless injury or loss of such plants can be tolerated.
- Legumes may be replanted 1 month or more after PastureGard application.
- When Reseeding Grasses:
- When PastureGard is applied before reseeding, do not reseed treated areas for a minimum of three weeks after treatment.
- When PastureGard is applied following reseeding, to avoid grass injury, do not apply until grass seedlings are well established as indicated by tillering (usually after 4 true leaves have emerged), development of a secondary root system and vigorous growth.
- Grasses Grown for Seed: Do not use from early boot to milk stage if grass is being grown for seed production.
- Plant-back Restriction: Only wheat, barley, oats or perennial forage grasses may be planted in treated fields within 120 days following application of PastureGard.
Grazing and Haying Restrictions
Grazing or harvesting green forage:
1) Lactating dairy animals: Do not allow grazing or harvest green forage for lactating dairy animals from treated areas during the same growing season following application.
2) Other Livestock: No grazing restrictions.
Haying (harvesting of dried forage):
1) Do not harvest hay within 14 days after application.
Slaughter Restrictions: Withdraw livestock from grazing treated grass or consumption of treated hay at least 3 days before slaughter. This restriction is applicable to grazing or harvest of hay from treated areas during the same growing season following application.
GROUND APPLICATION: To minimize spray drift, apply PastureGard in a total spray volume of 5 or more gallons per acre using spray equipment designed to produce coarse or larger droplets per ASAE S-572 standard. Refer to the spray equipment manufacturer’s recommendations for detailed information on nozzle types, arrangement, spacing and operating height and pressure. Spot treatments should be applied only with a calibrated boom to prevent over application. Operate equipment at spray pressures no greater than is necessary to produce a uniform spray pattern. Operate the spray boom no higher than is necessary to produce a uniformly overlapping pattern between spray nozzles. Do not apply with hollow cone-type insecticide nozzles or other nozzles that produce a fine-droplet spray.
Rangeland and Permanent Pastures: Both fixed-wing and helicopter equipment may be used to apply this product on rangeland, permanent pastures and pine plantations, but fixed-wing aircraft require additional drift mitigation measures.
To minimize spray drift, apply PastureGard in a total spray volume of 3 or more gallons per acre using spray. Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, including droplet size and equipment type, determine drift potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high potential for temperature inversion. Spray drift from aerial application can be minimized by applying a coarse spray at per USDAARS/ PAASS or nozzle manufacturer’s guidelines or by using straightstream nozzles directed straight back. Do not operate using a spray boom no longer than 75% of wing span or 85% of rotor width. For fixed-wing aircraft, maximum speed during application is limited to 140 mph and application height above the vegetation canopy should not exceed 10 ft.
General Woody Plant Control: Apply PastureGard when conditions are favorable for active growth, but only after leaves are fully expanded and terminal growth has slowed. Application to immature foliage during periods of rapid terminal growth will result in rapid defoliation, but translocation of the herbicide and woody plant control may be reduced. If brush has been mowed, best results are obtained when at least 9 - 12 months of regrowth following mowing is allowed before herbicide application (12 months is recommended in areas where growth conditions such as low rainfall have limited brush regrowth following mowing). Adequate soil moisture before and after treatment as well as healthy foliage at the time of application is important for optimal effectiveness. PastureGard will control only broadleaf plants that are emerged at the time of application.
Use higher spray volumes to ensure adequate foliar coverage where brush canopy is dense. If applied in tank mix, follow applicable use directions, precautions and limitations on the respective labels (see instructions for tank mixing under Mixing Directions). The optimal rate of PastureGard will depend on brush size as well the species. For smaller brush (less than about 6 feet tall), 3-4 pints/acre will be sufficient. For larger brush and mixed brush canopies, apply 4-8 pints/acre.
