Problems solved by technology

Phorate granules have high toxicity and heavy residues, so they are not suitable for popularization and use. Chlorpyrifos granules and abamectin granules are high in cost and short in duration, and it is difficult to popularize them in large quantities. Although the price of common phoxim granules is moderate , but the duration is short, and the control effect on underground pests is not ideal.

Embodiment 1

[0016] Weigh 3.3 parts of phoxim original drug and add to 10 parts of white carbon black, mix evenly, set aside. Mix the above-mentioned mother powder with 80.5 parts of sieved attapulgite (about 20-40 mesh in particle size) and add them to the coating granulator for stirring, and add 10% polyvinyl alcohol aqueous solution gradually while stirring. 1 part, 0.5 part of organic silicon synergist, 2 parts of calcium lignosulfonate, 0.5 part of triphenyl phosphate and 0.2 part of acid red B, mix well and discharge, then dry and sieve to get 100 parts of qualified products .

Embodiment 2

[0018] Weigh 5 parts of emulsifiable concentrate preparation with high content of phoxim and add to 20 parts of calcium carbonate, mix evenly, set aside. Mix the above-mentioned mother powder with 55 parts of sieved attapulgite (with a particle size of about 20-40 mesh) and add them to a coating granulator for stirring, and add 10 parts of 10% starch aqueous solution gradually while stirring, 2 parts of methyl synergist, 5 parts of fatty alcohol polyoxyethylene ether, 2 parts of phosphorous acid and 1 part of acid scarlet, mixed well and discharged, dried and sieved to obtain 100 parts of qualified products.

Embodiment 3

[0020] Weigh 3 parts of phoxim original drug and add to 4.7 parts of diatomaceous earth, mix evenly, set aside. Mix the above-mentioned mother powder with 90 parts of sieved attapulgite (about 20-40 mesh in particle size) and add them to the coating granulator for stirring, and add 1 part of 10% dextrin solution gradually while stirring , 0.1 part of synergistic ether, 1 part of sodium dodecylbenzenesulfonate, 0.1 part of hydroxysulfonic acid and 0.1 part of pinnatine violet, mix well and discharge, dry and sieve to obtain 100 parts of qualified products.

Abstract

The invention discloses a formula and a preparation method of a granular pesticide. The granular pesticide comprises the following components in parts by mass: 3-5 parts of hoxim, 1-20 parts of adsorbent, 0.1-2 parts of stabilizer, 0.1-2 parts of synergistic agent, 1-5 parts of dispersant, 1-10 parts of adhesive, 0.1-1 part of coloring agent and 55-90 parts of carrier. By adopting attapulgite as the pesticide carrier, the low-toxicity low-residue pesticide phoxim can be mixed with the adhesive and auxiliary agents in proportion to prepare granules, so that the invention not only overcomes the defects of short persistence of the conventional phoxim granules, but also has certain fertilizer efficiency, soil improvement and environmental protecting performance.

Description

technical field [0001] The invention relates to a formulation of a granule pesticide for preventing and controlling underground pests of crops and a preparation method thereof, in particular to a formulation of a phoxim granule and a preparation method thereof. Background technique [0002] There are many kinds of underground pests of crops, mainly cutworms, needleworms, grubs, mole crickets, scarabs, etc., which can basically harm all kinds of crops and cause serious damage. At present, the most commonly used control method in production is to spray granular pesticides into the soil. Common granule pesticides include phoxim granules, phorate granules, chlorpyrifos granules, abamectin granules, etc. Phorate granules have high toxicity and heavy residues, so they are not suitable for popularization and use. Chlorpyrifos granules and abamectin granules are high in cost and short in duration, and it is difficult to popularize them in large quantities. Although the price of com...
