Abstract

The invention belongs to emamectin pesticides and discloses an emamectin benzoate-algae slow release type water dispersible granular insecticide and a preparation method. In the traditional pesticide formulation, emulsifiable concentrate has many potential safety hazards in the processes of production, storage and transportation and causes huge damage to the ecological environment in the process of use; and powder formulations bring adverse influences to users and surrounding environment in the process of use due to the small granules and easy drifting. The preparation method comprises the steps of: absorbing raw emamectin and a plant growth regulator by using algae as a carrier, then adding a dispersing agent, a wetting agent, a disintegrating agent, a binder and a micro-element fertilizer, carrying out ultramicro airflow milling, extruding and granulating to prepare an insecticide-fertilizer compound slow release type water dispersible granular formulation. The invention has the advantages of effectively prolonging effective duration, reducing pesticide dosage, performing dual effects of land fertilizing and plant protection by adopting an insecticide-fertilizer compound and having convenient application, labor intensity reduction, easy raw material obtaining, simple processing technology, low cost and suitability for industrial scale production.

Description

technical field [0001] The invention belongs to the emamectin benzoate pesticide, in particular to an emamectin benzoate-algae sustained-release water-dispersible granule insecticide and a preparation method. Background technique [0002] Abamectin, the English name Avermectins, is a sixteen-membered macrocyclic lactone compound with insecticidal, acaricidal, and nematicidal activities. In 1975, Japan's Kitasato Institute (Kitasato Institute) obtained a soil sample from Kawana City, Shizuoka, Japan. isolated from. Avermectins are a new type of antibiotics with the characteristics of novel structure and dual use in agriculture and livestock. With the improvement of people's living standards and the demand for green food, the use of abamectin biopesticides is increasing. [0003] In 1984, Merk & Co. of the United States began to use avermectin as the lead compound for avermectin through derivative synthesis. In 1994, the company optimized and developed a new type of syntheti...
