15%氰氟草酯·吡嘧磺隆可湿性粉剂是用于防除移栽水稻田中一年生杂草的茎叶除草剂,随着用药量增加,移栽水稻田中一年生杂草株防效、鲜质量防效提高.15%氰氟草酯·吡嘧磺隆可湿性粉剂在本试验剂量范围内不但对当茬水稻安全,且对水稻有增产作用.本研究表明,15%氰氟草酯·吡嘧磺隆可湿性粉剂可用于防除移栽水稻田中多种一年生杂草,随着用药量增加,防除移栽水稻田中一年生杂草株防效、鲜质量防效也随之增加。15%氰氟草酯·吡嘧磺隆可湿性粉剂在本试验剂量范围内不但对当茬水稻安全,且对水稻有增产作用。建议在移栽水稻田中一年生杂草4叶期前用15%氰氟草酯·吡嘧磺隆可湿性粉剂900 g/hm2防除移栽水稻田中一年生杂草,一年生杂草4叶期后用15%氰氟草酯·吡嘧磺隆可湿性粉剂100 g/hm2防除移栽水稻田中一年生杂草。
