Timing -
Apply from spring when plant is fully leafed out and actively growing to early bud stage.
Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. Application can result in bare ground as glyphosate is not selective. 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.):
imazapyr
Common product name:

Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. Applications can result in bare ground as imazapyr is not selective and can remain in the soil for several months to over a year depending on application rate. 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.):
picloram
Common product name:
Tordon K; Trooper 22K
|
Rate -
(broadcast) 32 - 64 fl oz/A (0.5 - 1 lb a.e./A)
(spot) Equivalent to broadcast rates.
Timing -
Apply from spring when plant is fully leafed out and actively growing to early bud stage.
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 to plants. Do not compost treated plants as herbicide can persist through composting process.
