摘要
安融乐(3%卵磷脂·维生素E悬乳剂)是从大豆中提取的新型生物助剂,已经广泛应用于农药特别是除草剂的增效。为了弄清安融乐作为助剂与麦田除草剂混用后是否能提高除草剂对阔叶杂草的防除效果,于2017—2018年开展了安融乐对麦田除草剂7.5%啶磺草胺水分散粒剂(300.0、375.0、562.5 mL/hm^2)和3%甲基二磺隆水分散粒剂(420.0、525.0、787.5 mL/hm^2)的增效效果及对小麦安全性的田间药效试验。结果表明,45 mL/hm^2安融乐与2种供试除草剂3个剂量混用都能显著提高对猪殃殃的防除效果。安融乐与2种供试除草剂中剂量混用,药后45 d对猪殃殃的株防效和鲜重防效分别提高8.40%和10.78%、11.49%和12.42%。安融乐与2种供试除草剂3个剂量混用均对小麦安全。另外,2种供试除草剂中剂量与45 mL/hm^2安融乐和45 g/hm^2碧护(0.136%赤·吲乙·芸苔可湿性粉剂)混用对猪殃殃的防治效果与不加碧护的效果相当,且可以显著促进小麦生长。
AnnGro^?(3%lecithin and vitamin E suspension concentrate)is a new type of biological adjuvant obtained from soybeans that is widely applied to synergize pesticides,particularly herbicides.Field trials were conducted during March to June,2018 to determine whether AnnGro^?adjuvant could improve 7.5%pyroxsulam WG(300,375,662.5 mL/hm^2)and 3%Mesosulfuron-methyl WG(420、525、787.5 mL/hm^2)efficacy on broadleaf weeds.Efficacy of both herbicides for controlling Galium aparine var.tenerum was significantly improved by tank mixing with AnnGro^?,especially the medium herbicides doses.AnnGro?(45 mL/hm^2)improved efficacy based on weed mortality and fresh weight reduction at the intermediate herbicide dose 8.40%and 10.78%,and 11.49%and 12.42%,compared with the herbicides used alone.When VitCat?(0.136%GA·IAA·BR WP)was added at 45 g/hm^2 to these treatments,similar control efficacy to broadleaf weed was obtained but wheat growth was improved.
