dicamba
Common product name:
Banvel; Clarity
|
Rate -
(broadcast) 16 - 64 fl oz/A (0.5 - 2.0 lb a.e./A)
(spot) Equivalent to broadcast rates.
Timing -
Apply during flower-bud stage through the fall as long as leaves are green.
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. Rates > 16 fl oz/A (0.5 lb a.e./A) may cause stunting and discoloration of sensitive grasses, such as smooth brome.

Active Ingredient (A.I.):
picloram
Common product name:
Tordon K; Trooper 22K
|
Rate -
(broadcast) 8 - 32 fl oz/A (0.13 - 0.5 lb a.e./A)
(spot) Equivalent to broadcast rates.
Timing -
Apply during flower-bud stage through the fall as long as leaves are green.
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. Remains in the soil for over one year depending on application rate and has the potential to contaminate surface runoff water during this timeframe. Maintenance of a vegetative buffer strip is recommended between the areas picloram 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. Do not compost treated plants as herbicide can persist through composting process.
