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. |
