摘要:
试验结果表明,31%丙草胺.丙炔噁草酮EW以418.5-744g/hm2(90-160mL/0.067hm2)的施药量,拌成毒土(沙)20kg混匀后均匀撒施施于水稻移栽田,田间保持3-5cm水层5-7天后移栽秧苗。施药45d后对水稻移栽田一年生杂草总草的株防效及鲜重防效分别为95.2%、96.51%,防除效果较好,且对水稻秧苗生长安全。

Conteol Effect of Pretilachlor.Oxadiargyl 31% EW on the One-year-old Weeds in Rice Transplanting Field
()
Abstract:
The test results show that after the rice seedling was transplanted to rice field after water processing for 5-7d, pretilachlor.oxadiargyl 31% EW was applidd;and the effective component of application rate was 418.5-744g/hm2(preparation dosage was 90-160mL/0.067hm2).Under the dosage of 300kg/hm2,poisoned soil(sand)was obtained and sprayed to rice field.The water layer in field was maintained at 3-5cm for 5-7d. After 45 days,the effects of this treat on the one-year-old weeds were 95.2percent in stem effect,and 96.51 percent fresh weight effect.The control effect was relatively good and was safety to the growth of the rice.
Key words:  pretilachlor.oxadiargyl 31% EW  one-year-old weeds  stem effect  fresh weight effect
