| Abstract: | To explore control efficiency and safety of First Rate in small red bean field,taking First Rate,First Rate＋Fomesafen,First Rate＋Acifluorfen and First Rate＋Imazethapyr as treatments to research their phytocidal effect of broadleaf weeds and safety in small red bean field.The results showed that phytocidal effect of First Rate 30and 45g·hm-2,First Rate 30g·hm-2＋Imazethapyr 1 500g·hm-2 on Commelina communis Linn,Cirsium setosum,Sonchus arvensis and the other broadleaf weeds were better.There was little effect on the height of the small red bean first and restored growth after 7days.While it had no effect on the producting of small red bean,so that these could be safely used. |
