Abstract/Contents:"Numerous field tests in South America over the last three years and recent research in the laboratory and greenhouse in the United States have shown haloxyfop-methyl to be effective for grass weed control in dryland rice. Field tests with haloxyfop-methyl in rice are planned in the United States for 1987. Haloxyfop-methyl,, a more active compound than sethoxydim, fluazifop or fenoxaprop, has a projected use rate of 40-80 g/ha for the control of numerous grass weeds, including Echinochloa, Leptochloa, Digitaria, Rottboellia, Paspalum, Eragrostis and others. Parameters evaluated to determine the performance of haloxyfop-methyl in rice included soil moisture, irrigation timing, growth stage, foliar and soil activity, variety and temperature. Some rice injury occurred if soil was puddled at application, but no injury was evident at recommended rates if soil was drained prior to treatment. Delaying irrigation for 48 hours after application further insured crop safety. The best treatment timing was found to be when the rice had at least 3 leaves, and haloxyfop-methyl has exhibited selectively across numerous japonica and indica rice varieties. Echinochloa growth stage was less important, as haloxyfop-methyl controlled this weed over a wide application window. Most crop safety was observed when rice was grown under warmer temperatures (37-26 degrees C) compared to cooler temperatures (26-22 degrees C). Finally, both soil and foliar activity of haloxyfop-methyl have been shown to contribute to the compound's total effectiveness. The basis of selectivity between rice and Echinochloa is under examination in the laboratory. In uptake studies with C-haloxyfop-methyl, 2 to 3 times more radioactivity was detected in Echinochloa compared to rice after 48 hours, although translocation quantities were similar. Further work is in progress."
