【摘要】 使用65％杀·苄可湿性粉剂375 g,750 g和1125 g/hm~2防治水稻1代二化螟和本田期杂草,表现出良好的兼防作用,对枯心的防效分别为91.99％,96.36％和100.00％,对本田期杂草的防效分别为73.19％,87.15％和90.19％。室内联合毒力测定(CTC=95.5162)和田间药效试验均表明,该药剂的复配效应为相加作用。更多还原

【Abstract】 The field trial was conducted on 65% monosultap-bensulfuronmethyl WP against first generation rice stem borer, Chilo suppressalis, and paddyfield weed with 375 g/hm2,750 g/hm2 and 1 125 g/hm2. The result indicated that the control efficacy of monosultap - bensulfuron-methyl WP were 91.99% at 375 g/hm2,96.36% at 750 g/hm2 and 100.00% at 1 125 g/hm2 against rice dead hearts of shoot, respectively, and 73.19%, 87.15% and 90.19% against paddyfield weed, respectively. Trie value of CTC was 95.5162. There had sysergistic effect between monosulta and bensulfuron methyl by CTC and field effective trial.更多还原
