Managing Rice in the Mid-South

By Chris McClain, Market Development Specialist

The fundamentals for successful weed management in rice are not uniquely different from those of other Mid-South crops. Unlike other row crops, however, there are few chances for do-overs in rice, and it is essential to do it right the first time.

Beginning the season with clean fields requires the use of overlapping contact and residual herbicides in conjunction with appropriate cultural practices. That often involves mechanical tillage or an effective herbicide burndown program, preferably one that provides both contact and residual activity. At-planting recommendations call for contact herbicides as needed plus grass and broadleaf residuals.

After your rice crop is established, in-season scouting by trusted advisers, combined with herbicide treatments when weeds are small and actively growing, is the key to success. 

Corteva Agriscience provides the broadest portfolio of rice herbicides available in the industry with flexibility across all cropping systems, including Clincher® SF, Grasp® SC, RebelEX®, Grandstand® R, Loyant® and Novixid® herbicides. 

A flagship postemergence grass herbicide with a long-standing reputation, Clincher is the go-to grass herbicide for pre- and post-flood applications. Clincher is being applied earlier in the crop, tank-mixed with residual products, and remains a flexible option throughout the rice crop and across all cropping systems. 

Grasp SC is a powerful contact plus residual herbicide in the portfolio, providing as much as 21 days residual for barnyardgrass control.

With powerful contact control and residual activity for both grass and broadleaf weed species, RebelEX is a heavy hitter.

Grandstand is an auxin product that is widely utilized for postemergence control of key broadleaf weeds. 

Loyant provides outstanding postemergence control of a wide array of broadleaf weeds and grasses, including control of aquatics and Palmer amaranth. 

Available only in Louisiana, Novixid is the newest addition to our rice herbicide lineup and combines the attributes of Loyant and Grasp in a convenient premix focusing on premium broadleaf, grass and sedge weed control.
