Abstract

The invention discloses a water dispersible granule for preventing and controlling cotton bollworms. The water dispersible granule for preventing and controlling the cotton bollworms comprises the following raw materials in parts by weight: 8 to 18 parts of stellera chamaejasme extracts, 10 to 20 parts of tripterygium wilfordii extracts, 3 to 7 parts of isatis root extracts, 3 to 7 parts of subprostrate sophora extracts, 1 to 3 parts of a wetting agent, 6 to 14 parts of a dispersing agent, 3 to 5 parts of a disintegrating agent, 1 to 2 parts of a binder, 0.5 to 1.5 parts of a dispersing auxiliary agent and 50 to 70 parts of a carrier. The water dispersible granule provided by the invention takes the traditional Chinese medicine extracts with insecticidal and antibacterial effects as effective components and avoids environmental pollution after being applied to the field; meanwhile, the prepared products are uniform in granularity and smooth, avoid mutual bonding when being stored under the conditions of high temperature and high pressure, and have high effective component content and high physical and chemical stability.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a water-dispersible granule for controlling cotton bollworm and a preparation method thereof. Background technique [0002] At present, chemical pesticides have caused extremely serious harm to humans and other organisms, posed a huge threat to biodiversity, and caused incalculable and irreversible negative impacts on humans and nature. Botanical pesticides refer to the active substances that are directly used or extracted from the roots, stems, leaves, flowers, fruits, seeds, etc. of plants, or their secondary metabolites, which have insecticidal or bactericidal effects. The main modes of action of botanical insecticides on insects are as follows: stomach poisoning, contact killing, repelling and antifeedant effects, nerve anesthesia, etc. A formulation of water-dispersible granule pesticide is a granulated preparation developed on the basis of pesticide wettable ...
