Active Ingredient (A.I.):
2,4-D
Common product name:
Many (Aquatic: DMA 4 IVM; 2,4-D Amine 4)
|
Rate -
(broadcast) 1 - 2 lb a.e./A
(spot) Equivalent to broadcast rates.
Timing -
In spring apply to rosettes, bolting or flowering plants; in fall apply to rosettes as long as leaves are green. Applications to rosettes in the spring or fall are most effective.
Caution -
Use aquatically labeled product if potential exists for solution to contact surface water. 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.):
aminopyralid
Common product name:
Milestone
|
Rate -
(broadcast) 3 - 5 fl oz/A (0.05 - 0.08 lb a.e./A
(spot) Equivalent to broadcast rates.
Timing -
In spring apply to rosettes, bolting or flowering plants; in fall apply to rosettes as long as leaves are green.
Remarks -
14 fl oz/A can be used as long as less than half of the area is treated. Depending on the volume of solution applied per acre, typical mixtures for spot treatments are 2 - 4 mL Milestone per gallon of water. Biennial thistles are very sensitive to aminopyralid so using this high rate is not necessary to achieve control.
Caution -
Do not apply directly to water or to areas where surface water is present. Remains in soil for up to one 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. Do not compost treated plants as herbicide can persist through composting process.

Rate -
(broadcast) 8 - 32 fl oz/A (0.25 - 1 lb a.e./A)
(spot) Equivalent to broadcast rates.
Timing -
In spring apply to rosettes or bolting plants; in fall apply to rosettes 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 to plants. Rates >16oz/A (0.5 lb a.e./A) may cause stunting and discoloration of sensitive grasses, such as smooth brome.

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 - 2% (0.03 - 0.06 lb a.e./gal)
Timing -
In spring apply to rosettes, bolting or flowering plants; in fall apply to rosettes as long as leaves are green.
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.

Timing -
In spring apply to rosettes or bolting plants; in fall apply to rosettes as long as leaves are green.
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) 8 - 16 fl oz/A (0.13 - 0.25 lb a.e./A)
(spot) Equivalent to broadcast rates.
Timing -
In spring apply to rosettes, bolting or flowering plants; in fall apply to rosettes as long as leaves are green. Applications to rosettes in the spring or fall are most effective.
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.
