Abstract

The invention discloses an imidacloprid sustained-release granular insecticide and preparation and application thereof. The components of the imidacloprid sustained-release insecticide include imidacloprid, auxiliaries, coating agent and filler. The invention discloses a preparation method and application of the imidacloprid sustained-release insecticide. The imidacloprid sustained-release insecticide slowly releases the beneficial components so as to achieve the aim of reducing insecticide applying times.

Description

technical field [0001] The invention relates to the fields of pesticide technology and plant protection, in particular to the preparation and application of imidacloprid sustained-release granules. Background technique [0002] Imidacloprid is a super-efficient neonicotinoid insecticide with broad-spectrum, high efficiency, low toxicity, and low residue. It is not easy for pests to develop resistance, and it is safe for humans, animals, plants, and natural enemies. It also has contact, stomach, and systemic toxicity. and other multiple functions. After the pests are exposed to the pesticide, the normal conduction of the central nervous system is blocked, causing them to paralyze and die. [0003] The common English name of imidacloprid is imidacloprid, and its chemical name is 1-(6-chloropyridin-3-pyridylmethyl)-N-nitroimidazolidin-2-ylamine. The structural formula is: [0004] [0005] Imidacloprid is a nitromethylene-type systemic insecticide, and it is the action bo...
