Abstract

The invention relates to the field of pesticides, particularly relates to a compound formula of a pesticide and a preparation method thereof, and discloses a compound formula of trichlorphon and diazinon and a preparation method of granules and fine granules. The granules and fine granules are characterized by being prepared from the following components in parts by weight: 1-10 parts of trichlorphon the content of active compound of which is more than or equal to 90 percent, 1-10 parts of diazinon the content of an active compound of which is more than or equal to 90 percent, 1-10 parts of a stabilizing agent, 1-3 parts of an adhering agent, and 67-96 parts of a carrier. The compound has the advantages of enlarging a pesticide control spectrum as all agents can be made good for deficiency and complement, increasing the insecticidal efficacy, and having no remarkable increase in compounding toxicity.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound formulation of pesticides and a preparation method thereof. Background technique [0002] Highly toxic pesticides have caused many problems, especially the poisoning of pesticide applicators and excessive residues of agricultural products. The requirements for alternative medicines are: the effect should not be lower than that of the medicine being replaced; the cost of use should not be much higher than that of the medicine being replaced; the toxicity to humans and animals should be low, and it cannot be a highly toxic species; the impact on the environment should not be lower than that of the medicine being replaced. The species are larger, mainly natural enemy risks and aquatic organism risks; the development speed of pest resistance should be assessed accordingly; farmers can easily grasp and understand. Contents of the invention [0003] The technical problem to be s...
