A rates applied during 3 consecutive years. Grazing livestock is prohibited. Irrigation or shallow incorporation is recommended for treatments made November through February, if no rain falls within 2 weeks after application. Irrigate within 24 hours to wet soil 2 to 4 inches deep if applied March through October. Shallow mechanical incorporation seems to enhance activity.
Performance is reduced with excessive plant residues on soil surface.
Do not apply within 35 days of harvest. A Apply late fall or early spring to bare soil or after existing vegetation has been destroyed by tillage or use of a foliar-active herbicide. Use higher rates or split treatments and apply in fall and spring for longer residual control. Irrigate with at least 0.5 inch of water or rain to activate herbicide. Shallow cultivation can provide control of newly germinated weeds without reducing herbicide activity.
