Abstract

The invention discloses an imidacloprid wettable powder seed-dressing agent for preventing and controlling Aphis gossypii Glover and a preparation method and application thereof and relates to the field of agricultural pharmacology. According to the seed-dressing agent, imidacloprid serving as a main active ingredient, humic acid serving as a synergis, as well as a suspending agent, a wetting agent, an anti-flocculating agent, a carrier and a filling material are fully and uniformly mixed by a jet mill, thus preparing the imidacloprid wettable powder seed-dressing agent for preventing and controlling Aphis gossypii Glover. The prevention and control effect of the imidacloprid wettable powder seed-dressing agent on Aphis gossypii Glover can be over 80 percent, the effect lasting period is about 60 days, and the imidacloprid wettable powder seed-dressing agent has an effect of obviously promoting growth and development of cotton. Meanwhile, the imidacloprid wettable powder seed-dressing agent has the characteristics of high safety, low residue content, low price, high selectivity and the like.

Description

technical field [0001] The invention relates to the field of pesticide science, in particular to an imidacloprid wettable powder seed dressing agent for controlling cotton aphids, a preparation method and application thereof. Background technique [0002] Cotton aphid (Aphis gossypii Glover) is one of the most important pests in cotton production. In recent years, cotton aphids have been outbreaks and damages in major cotton areas of the country year after year, seriously affecting the yield and quality of cotton. In production, in order to control the harm of cotton aphids, farmers often use more spraying frequency and concentration to prevent and control cotton aphids, which leads to serious drug resistance of cotton aphids, and falls into a vicious circle that becomes more and more serious. [0003] In recent years, some seed dressing agents for cotton aphid control have appeared on the market with unreasonable formula, poor control effect, short duration of effect, and ...
