| Abstract: | To screen effective herbicides which are suitable for dry direct-seeding rice field in Sichuan, this experiment selected metamifop, fluroxypyr- meptyl, flucetosulfuron, pyraclonil, bensulfuron, butachlor and benzyl-butyl to screen effective herbicides, and through the investigation of weed species and quantity to study he weed control effect of the seven herbicides. The results showed that 10% metamifop+ 20% fluroxypyrmeptyl EC, 1.8% pyraclonil SP and 35% benzyl-butyl WP had a good control effect on the gramineous weeds and broadleaf weeds. At 30 days, the controlling effect reached above 91% for each plant and fresh weight. Fur hermore, they had better safety for rice seedling, and could be popularized and applied in dry directseeding rice field in Sichuan. Therefore, 10% metamifop+ 20% fluroxypyr-meptyl EC, 1.8% pyraclonil SP and
35% benzyl-butyl WP have wide prospect in dry direct-seeding rice field in Sichuan. |
