近年来,棉铃虫对作物危害十分严重,给棉花生产带来了巨大损失,用复配农药防治棉铃虫已证明是一种能有效地克服抗药性,达到良好防效的有力措施。 为了提高复配制剂的渗透,展着、缓释和粘附能力,从而达到延长药效提高防效的目的。再者,通过加入某些助剂也能达到促进棉花生长发育,进而达到防虫促产的目的。我们在室内安排了复配农药的筛选,并做了简单的田间试验。
In recent years, the cotton bollworm is very harmful to the crop, which has brought huge losses to the cotton production. Using the compound pesticide to prevent and control the cotton bollworm has proved to be a powerful measure to effectively overcome the resistance and achieve the good control effect. In order to improve the compound formulation penetration, spreading, sustained release and adhesion, so as to achieve the purpose of prolonging the efficacy and improving the prevention effect. In addition, by adding some additives can also be achieved to promote cotton growth and development, and thus achieve the purpose of pest control. We arranged a screening of compound pesticides indoors and conducted a simple field experiment.
