通过对20%唑酰草胺·灭草松ME防除水稻直播田一年生杂草及对水稻安全性的试验,明确了每667 m2用20%唑酰草胺·灭草松ME在有效剂量下,与10%韩秋好EC、48%灭草松AS相比较除草效果显著,杀草谱广;在水稻直播田中,当水稻秧苗2叶期后,杂草处于2~4叶期,用剂量为210~240 mL/667 m2(630~720 a.i.g/hm2)时,能有效地防除水稻直播田一年生单双子杂草和异型莎草,证明了在水稻直播田应用唑酰草胺·20%灭草松ME对水稻是安全的。
By controlling the annual weeds in the direct seeding rice field and testing the safety of the rice with 20% dacoxamide and mebendatone ME, it is clear that using 20% pyriproxyfenstate ME per 667 m 2 at an effective dose, Compared with 10% Han Qiuhao EC and 48% Methyl Asp, the herbicidal effect was obvious and the herbicide was broad spectrum. In the direct seeding field of rice, when the second leaf stage of rice seedling, the weeds were in the 2-4 leaf stage, 210 ~ 240 mL / 667 m2 (630 ~ 720 aig / hm2) could effectively control annual mono- and cross-sedge weeds in direct-seeded rice fields, and proved that the application of pyrazoxamide · 20% Pine ME is safe for rice.
