Active Ingredient (A.I.):
napropamide
Common product name:
Devrinol 50-DF
|
Rate -
(spot) 1.8 - 7.1 lb/A (1 - 3.5 lb a.i./A)
Timing -
Apply prior to germination of seedlings. While spring applications will maximize control, fall or winter applications may also suppress seedlings, depending upon environmental conditions.
Remarks -
Reduced efficacy can be expected if <0.6" of rainfall occurs within 2-3 days of application.
Caution -
Do not apply directly to water or to areas where surface water is present. Do not apply more than once a year. Avoid using napropamide in areas where soils are composed of more than 10% organic matter. Napropamide remains in the soil for up to a year depending on application. Maintenance of a vegetative buffer strip is required between the areas napropamide is applied and surface water features or sensitive terrestrial habitats. 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.):
pendimethalin
Common product name:
Pendulim Aquacap; Prowl
|
Rate -
(spot) 90 fl oz/A (2.7 lb a.i./A)
Timing -
Apply prior to germination of seedlings. While spring applications will maximize control, fall or winter applications may also suppress seedlings, depending upon environmental conditions.
Remarks -
Reduced efficacy can be expected if <0.5" of rainfall occurs within 30 days of application.
Caution -
Do not apply directly to water or to areas where surface water is present. Do not exceed applications of 67 fl oz/A on home lawns, parks, schools, and playgrounds. 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.):
glyphosate
Common product name:
Roundup Pro; many others (Aquatic: Rodeo; AquaNeat)
|
Rate -
(broadcast) 1.7 - 3.7 lb a.e./A
(spot) For a 3 lb a.e./gal product. 1 - 2% (0.03 - 0.06 lb a.e./gal)
Timing -
Apply when target species is actively growing and fully leafed out.
Remarks -
A wick application is effective on shorter plants that are taller than desirable species, with 33 - 75% (1.5 - 3.4 lb a.e./gal).
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.):
triclopyr
Common product name:
Garlon 4; Element 4 (Aquatic: Garlon 3A; Element 3A)

Rate -
(broadcast) 128 - 256 fl oz/A (4 - 8 lb a.e/A)
(spot) 1 - 2% (0.1 - 0.2 lb a.e./gal)
Timing -
Apply when target species is actively growing and fully leafed out.
Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. 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.):
imazapyr
Common product name:
Stalker (Aquatic: Habitat; Imazapyr 2sl)
|
Rate -
(spot) 6 - 9% in oil (0.1 - 0.2 lb a.e./gal)
Timing -
Apply any time of year.
Remarks -
Products containing this active ingredient can have different instructions for mixing. Labels will recommend mixing the product in a water or oil based carrier (e.g. basal bark oil). Consult the label to determine the appropriate carrier.
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 22K; Trooper 22K
|
Rate -
(spot) 50 - 100% (0.3 - 0.5 lb a.e./gal)
Timing -
Apply any time of year.
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.
