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) For a 3.8 lb a.e./gal product. 0.6 - 1% (0.025 - 0.04 lb a.e./gal)
Timing -
Apply to rosettes in fall or spring. Applications after bolting may be less 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) 4 - 7 fl oz/A (0.06 - 0.1 lb a.e./A)
(spot) Equivalent to broadcast rates.
Timing -
Apply to rosettes in fall or spring.
Remarks -

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.

Active Ingredient (A.I.):
imazapic
Common product name:
Plateau
|
Rate -
(broadcast) 8 - 12 fl oz/A (0.15 - 0.2 lb a.e./A)
(spot) 0.25 - 1.5% (0.005 - 0.025 lb a.e./gal)
Timing -
Apply to rosettes in fall or spring.
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.

Active Ingredient (A.I.):
aminocyclopyrachlor + metsulfuron
Common product name:
Streamline
|
Rate -
(broadcast) 4.75 - 9.5 oz/A (aminocyclopyrachlor: 1.9 - 3.75 oz a.i./A + metsulfuron: 0.6 - 1.2 oz a.i./A)
(spot) 0.2 - 0.4 oz/gal (aminocyclopyrachlor: 0.08 - 0.16 oz a.i./gal + metsulfuron: 0.03 - 0.05 oz a.i./gal)
Timing -
Apply to rosettes in fall or spring.
Caution -
Do not apply directly to water or to areas where surface water is present. Avoid using Streamline in areas where soils are permeable, particularly where the water table is shallow as groundwater contamination may result. Streamline remains in the soil for months depending on application rate and has the potential to contaminate surface runoff water, especially on poorly draining soils or areas with shallow groundwater. Maintenance of a vegetative buffer strip is recommended between the areas Streamline 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.
