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.):
dicamba
Common product name:
Banvel; Clarity

Timing -
Apply to rosettes in the fall or spring or to flowering plants.
Remarks -
While effective on new infestations, multiple applications will only suppress established populations.
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 > fl 16oz/A (0.5 lb a.e./A) may cause stunting and discoloration of sensitive grasses, such as smooth brome. Avoid overspray or drift to desirable plants since even minute quantities of the spray may cause severe injury.

Active Ingredient (A.I.):
glyphosate
Common product name:
Roundup Pro; many others (Aquatic: Rodeo; AquaNeat)
|
Rate -
(broadcast) 0.75 - 1.5 lb a.e./A
(spot) For a 3 lb a.e./gal product. 1 - 3% (0.03 - 0.09 lb a.e./gal)
Timing -
Apply to rosettes in the fall or spring or to flowering plants. Use higher rates when air and soil temperatures drop below 40°F to maintain control.
Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. Applications 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.):
imazapic
Common product name:
Plateau
|
Rate -
(broadcast) 6 - 10 fl oz/A (0.05 - 0.15 lb a.e./A)
(spot) 0.25 - 1% (0.005 - 0.02 lb a.e./gal)
Timing -
Apply to rosettes in the fall or spring or to flowering plants.
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. Imazapic can remain in the soil for months 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 Imazapic 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.
