Value Of Clearfield Rice: An Agronomic And Economic Approach, Tyler Paul Carlson Jan 2010

Value Of Clearfield Rice: An Agronomic And Economic Approach, Tyler Paul Carlson

LSU Master's Theses

Field studies were conducted in Crowley, Louisiana and Stoneville, Mississippi in drill seeded rice to evaluate weed control, yield, and economical returns with imazethapyr programs. Red rice (Oryza sativa) and barnyardgrass (Echinochloa crus-galli) was evaluated with imazethapyr applied alone at various rates and application timings. Imazethapyr, averaged across rate, controlled red rice 89% and barnyardgrass 90% when the initial application of imazethapyr was applied at emergence followed by (fb) a second application of imazethapyr two weeks after the initial application. While imazethapyr, averaged across timing, showed no differences for red rice and barnyardgrass control. Yield and economical returns were maximized ...
