Thrice

Cited Brand Name: CLINCHER CA

Thrice is a selective herbicide designed for post-emergence control of grass weeds in both drilled and water-seeded rice. It effectively targets actively growing grass species without impacting broadleaf weeds or sedges. The product becomes rainfast within two hours and does not provide pre-emergence or residual soil activity. Thrice is best used on actively growing grass weeds and can be applied up to 60 days before rice harvest. It is not recommended for use on stressed grass weeds or those impacted by prior herbicide applications.
