controlled at this rate.<br />

Weed Control<br />

2. Quackgrass control prior to seeding or after harvest:<br />

Rate (g ae per acre) Quack Grass Stage<br />

360 Season long control of light to moderate infestations. Apply when quack grass is 8 inches<br />

(20 cm) tall and has 3 to 4 actively growing leaves. Apply spring or fall.<br />

360 to 1020 Apply when quack grass has 3 to 4 new leaves for long term control of heavy infestations.<br />

Use high rate for sod-bound quack grass (left undisturbed for at least 2 years).<br />

DO NOT apply fall treatments if a hard frost has occurred (-5 o C) or if plants are drought stressed. Spread straw to allow<br />

regrowth and good spray coverage.<br />

Cultivation prior to application will result in reduced control. DO NOT cultivate between harvest and treatment when using<br />

fall applications. If using spring applications on fields which have been fall-tilled, delay application until the quack grass has<br />

reached the 4 to 5 leaf stage. (This will occur 1 to 4 weeks later on fall-tilled fields than in undisturbed fields).<br />

Cultivation after application usually will improve control of quack grass. Wait a minimum of 3 days after application before<br />

cultivating. If growing conditions are poor (cold or dry), particularly in the fall, waiting longer than 5 days may improve<br />

control.
