摘要

The use of ACCase-inhibiting herbicides without the correct addition of an adjuvant is a major cause of inefficient poaceous weed control. As such, this study aimed to assess the efficiency of a new clethodim/adjuvant formulated mixture in postemergence weed control for soybean crops. Two field experiments were conducted in the 2015/16 and 2016/17 growing seasons. A randomized block design, consisting of ten treatments with four repetitions, was used. The treatments and doses were: clethodim (108 g a.i. ha -1 ) + Lanzar? (0.5%), clethodim (108 g a.i. ha -1 ) + Nimbus? (0.5%), clethodim/adjuvant formulation at doses of (84 g a.i. ha -1 ), (96 g a.i. ha -1 ), (108 g a.i. ha -1 ), (120 g a.i. ha -1 ), (132 g a.i. ha -1 ), and (144 g a.i. ha -1 ), and a control with and without weeding. The formulated clethodim/adjuvant mixture showed high control at 7 days after application (DAA) in the 2015/16 growing season. At 28 DAA, formulation doses of 108 g a.i. ha-1 and higher exhibited superior weed control and the highest crop yields. Therefore, the use of correct adjuvant or formulated mixture is essential to increase the efficiency of clethodim herbicide.

(0.5%),Clethodim(108克A.I.Ha -1)+云峰? (0.5%),Clethodim /佐剂配方(84g Ai Ha -1),(96g Ai Ha -1),(108g Ai Ha -1),(120g ai ha -1),(132 G AI HA -1)和(144克AI HA -1),以及带有杂草的控制。制定的Clethodim /佐剂混合物在2015/16生长季节施用(DAA)后7天显示出高对照。在28 daa,配方剂量为108g a.i. HA-1和更高的表现出优异的杂草控制和最高的作物产量。因此,使用正确的佐剂或配制混合物对于提高克莱希普除草剂的效率是必要的。
