Active Ingredient (A.I.):
Tebuthiuron
Common product name:
Spike 20P; Tebuthiuron 20 P
|
Rate -
(broadcast) 10 - 20 lb/A (2 - 4 lb a.i./A)
(spot) 1.12 oz/100 sq ft (0.2 oz a.i./100 sq ft)
Timing -
Apply during late winter or early spring when soil is not frozen. Apply evenly to ground infested with target species.
Remarks -
Spike 20P can be used at rates as low as 2.5 lb/A (0.5 lb a.i./A), but partial control should be expected. Tebuthiuron is also available as a liquid formulation, Spike 80DF. This formulation is applied in a banded spray or as a spot treatment.
Caution -
Do not apply directly to water or to areas where surface water is present. Applications can result in bare ground as tebuthiuron is not selective and can remain in the soil for several years depending on application rate. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. In areas fitting this description Spike can be used at rates as low as 2.5 lb/A (0.5 lb a.i./A), but partial control should be expected. Any plant with a root system that intercepts the area treated with this herbicide can be damaged or killed. Do not apply more than 20 lb/A (4 lb a.i./A) a year. Do not apply this product more than once a year.

Brushmaster
|
Rate -
(broadcast) 2 - 3 gal/A (2,4-D: 2 - 3 lb a.e./A + 2,4-DP: 1 - 1.5 lb a.e./A + Dicamba: 0.5 - 0.75 lb a.e./A)
(spot) 1 - 4% (2,4-D: 0.01 - 0.04 lb a.e./gal + 2,4-DP: 0.005 - 0.02 lb a.e./gal + Dicamba: 0.002 - 0.01 lb a.e./gal)
Timing -
Apply when target species is actively growing and fully leafed out.
Caution -
Do not apply directly to water or to areas where surface water is present. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants. Rates > 16 oz/A (0.5 lb a.e./A) may cause stunting and discoloration of sensitive grasses, such as smooth brome.

Apply when target species is actively growing and fully leafed out. Early to mid flowering stage is the most effective time for treatment.
Remarks -
Avoid application if the target plant is drought stressed.
Caution -
Do not apply directly to water or to areas where surface water is present. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
aminocyclopyrachlor + chlorsulfuron
Common product name:
Perspective
|
Rate -
(broadcast) 4.75 - 8 oz/A (aminocyclopyrachlor: 1.9 - 3.15 oz a.i./A + chlorsulfuron: 0.75 - 1.25 oz a.i./A)
(spot) 0.2 - 0.3 oz/gal (aminocyclopyrachlor: 0.08 - 0.12 oz a.i./A + chlorsulfuron: 0.03 - 0.05 oz a.i./A)
Timing -
Apply when target species is actively growing and fully leafed out.
Caution -
Do not apply directly to water or to areas where surface water is present. Avoid using Perspective in areas where soils are permeable, particularly where the water table is shallow as groundwater contamination may result. Perspective remains in the soil for months depending on application rate and has the potential to contaminate surface runoff water, especially on poorly draining soils or areas with shallow groundwater. Maintenance of a vegetative buffer strip is recommended between the areas Perspective is applied and surface water features. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants. Do not compost treated plants as herbicide can persist through composting process.
