Abstract

The invention discloses a clothianidin sustained-release granule and a preparation method thereof, and belongs to the technical field of agricultural production. The clothianidin sustained-release granule comprises the following ingredients in part by weight: 40-50 parts of anhydrous calcium sulfate powder, 30-40 parts of kaolin, 5-15 parts of other carrier materials, 2-2.4 parts of clothianidin, 1.5-2.5 parts of white carbon black, 1-2 parts of a chromaticity regulator, 5-60 parts of a curing agent, 5-15 parts of an internal displacer, 0.01-5 parts of a unidirectional filtration membrane, 0.01-5 parts of crosslinking agent, 2-5 parts of amino acid chelate of magnesium and 1-5 parts of water; the preparation method comprises the following steps: firstly, preparing a sustained-release speed controlling agent; then mixing anhydrous calcium sulfate powder, kaolin, other carrier materials and clothianidin to obtain a mixture of particles; finally, spraying the sustained-release speed controlling agent onto the surface of the mixture of particles to obtain the clothianidin sustained-release granule. The clothianidin sustained-release granule can reduce labor and cost inputs, is high in release uniformity, significant in efficacy and strong in applicability, is not affected by the external environment, and can show stable efficacy at all stages of crop growth cycle.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a clothianidin sustained-release granule and a preparation method thereof. Background technique [0002] Clothianidin is a neonicotinoid insecticide. It is a new type of insecticide with high efficiency, safety and high selectivity. It is mainly used on crops, vegetables, fruit trees and other crops. [0003] During the growth cycle of crops, they are often harmed by pests such as aphids, leafhoppers, thrips, planthoppers and underground pests, which seriously affect the yield. Aphids suck the stems, leaves and tender ears of crops, affecting the photosynthesis of crops; leafhopper adults and nymphs suck the juice of crops, causing the leaves of the crops to pale and fall early; when the crops flower, thrips gather in the flowers, resulting in empty crops . Growers often use clothianidin to prevent and control common crop pests. In order to achieve significant r...
