助剂Quad7对除草剂烟嘧磺隆增效作用的研究

Research of synergism of adjuvant Quad7 on nicosulfuron

利用3种不同助剂,通过温室盆栽试验与田间试验相结合的方法,研究了Quad7、农药生物增效剂、非离子表面活性剂对烟嘧磺隆活性的影响。试验结果表明,在相同喷液量条件下,处理35、50、70 ga.i.hm-2加Quad7比不加防效分别提高15%、11%、4%;3种助剂对烟嘧磺隆增效强度分别为Quad7增效15%,农药生物增效剂增效9%,非离子表面活性剂增效7%;使用Quad7可以降低喷液量,提高药效。

Effect of Quad7, biological synergist and non-ionic surfactants on activity of nicosulfuron were conducted by the combination of potted plant experiments and field experiments. The results indicated that synergism of Quad7 on 35, 50, 70 ga.i .hm^-2 nicosulfuron was increased by 15%, 11% and 4%. Synergism of three adjuvants on Nicosulfuron were Quad7 by 15%, biological synergist by 9%, non-ionic surfactants by 7%. Quad7 can reduce volume and improve effect.
