Active Ingredient (A.I.):
fluazifop
Common product name:
Fusilade II
|
Rate -
(broadcast) 16 - 24 fl oz/A (0.25 - 0.38 lb a.i./A)
(spot) 0.5% (0.01 lb a.i./gal)
Timing -
Apply when grass is 6 - 10" tall. Apply only when the grass is actively growing.
Remarks -
Two applications per year may be necessary for older or denser 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. Fluazifop can remain in the soil for one to two 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 fluazifop is applied and surface water features. Overspray or drift to desirable grasses should be avoided, as even minute quantities of the spray may cause severe injury to grasses.

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 -
Apply when target plants are actively growing and 6 - 8" tall.
Remarks -
More than one application will be needed as entire rhizome will not be killed with a single application. Lower rates are effective if integrated with tillage. Wait 3 days after application before tilling.
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.):
quizalofop
Common product name:

(spot) 0.5 fl oz/gal (0.003 lb a.i./gal)
Timing -
Apply when target plants are actively growing and 6 - 10" tall. If quackgrass regrows, apply 6 - 7 fl oz/A (0.04 - 0.05 lb a.i./A) when it is actively growing and 4 - 8" tall.
Remarks -
Use nonionic surfactant for spot treatment.
Caution -
Do not apply directly to water or to areas where surface water is present.
