摘要
为了解不同除草剂及不同剂量茎叶处理对甘蔗杂草的防治效果,为甘蔗杂草防治提供药效的理论依据,2018年在云南省陇川县蔗区内开展了甘蔗杂草田间药效试验。结果表明:40%硝磺草酮SC、75%氯吡嘧磺隆WDG、80%莠灭净WP这3种药剂均对甘蔗的安全性评价较好,40%硝磺草酮SC(375mL/hm^2)+75%氯吡嘧磺隆WDG(120g/hm^2)+80%莠灭净WP(1500g/hm^2)复混剂以及40%硝磺草酮SC(300mL/hm^2)+80%莠灭净WP(1500g/hm^2)复混剂对甘蔗杂草有较好的防治效果,株数综合防效和鲜重防效均达100%,尤其对莎草类、双子叶杂草类效果较为明显。
To understand the different herbicide dosage stem leaf on sugarcane weed control effect, the test was carried out by sugarcane weed field in Longchuan of Yunnan sugarcane area in 2018. It provided theoretical basis for sugarcane weed control efficacy. The results showed that the 40% Mesotrione SC, 75% Halosulfuron methyl WDG and 80% Ametryn WP had better safety evaluation of sugarcane. The compounding agent of 40% Mesotrione SC(375 mL/hm 2 )+75% Halosulfuron methyl WDG(120 g/hm^2 )+80% Ametryn WP(1500 g/hm^2 ) and 40% Mesotrione SC(300 mL/hm^2 )+80% Ametryn WP(1500 g/hm^2 ) had a good control effect on sugarcane weeds, with 100% plant control effect and fresh weight control effect, especially on sedge and dicotyledon weeds.
