The recommended method of control for glyphosate-resistant (GR) Italian ryegrass in Mississippi is to apply residual herbicides in the fall; however, these treatments may negatively affect rice performance. This study was conducted to evaluate rice performance following fall-applied treatments of residual herbicides + flumioxazin at different rates. Pooled over with and without flumioxazin and herbicide rates, clomazone and dimethenamid-P caused <10% injury 28 d after emergence. Acetochlor delayed rice maturity by 2 d to clomazone, dimethenamid-P, and flumioxazin. Rice density was reduced ≥4 plants m−2 following fall-applied acetochlor and dimethenamid-P compared to nontreated plants. Rough rice yields were reduced by ≥670 kg ha−1 with fall-applied acetochlor alone and dimethenamid-P compared to nontreated plants. Acetochlor should not be used as a fall-applied treatment in areas where rice is scheduled to grow the following season. Given current label restrictions and rice injury caused by acetochlor and dimethenamid-P, clomazone remains the only viable option for controlling GR Italian ryegrass where rice is scheduled to be planted the following spring.
