Abstract

The invention relates to the technical field of pesticide preparations, in particular to pesticide powder and a preparation method thereof. The pesticide powder is prepared from, in weight percent, 5-40% of pesticide active components, 5-25% of sustained-release materials, 2-15% of organic solvents, 0.5-5% of emulsifiers, 1-5% of dispersing agents, 0.5-2.5% of stabilizers, 0.3-0.7% of thickening agents and the balance water. The pesticide powder is treated by a special film coating technology and can be regulated according to specific pesticide applying scene requirements, the sustained-release period of the pesticide preparations is effectively prolonged, the activity of pesticides can be improved, spraying frequency and dosage can be decreased, and the pesticide powder has the advantagesof rapid and stable fertilizer effects and slow lasting pest-killing pesticide effects.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a pesticide powder and a preparation method thereof. Background technique [0002] In the field of agriculture, pesticides are also needed. Pesticides refer to chemical substances used to prevent, eliminate or control diseases, insects, grasses and other harmful organisms that endanger agriculture and forestry, as well as chemical compounds that purposefully regulate the growth of plants and insects. , These substances are mainly derived from one substance or a mixture of several substances and their preparations from organisms and other natural substances. In agricultural production, pesticides can guarantee and promote the growth of plants and crops, eliminate pests, sterilize bacteria, and kill harmful animals. Insecticides include a class of systemic drugs, which are absorbed and transported to the whole plant through plant seeds, roots, stems, and leaves. It...
