Abstract

The invention discloses a grain storage anti-insect pesticide and a preparation method thereof, and relates to the technical field of anti-insect pesticide production. The grain storage anti-insect pesticide comprises a shell and a pesticide; the shell is prepared from the following component raw materials in parts by weight: 40 to 50 parts of starch, 20 to 30 parts of bentonite, 10 to 20 parts of gypsum and 25 to 35 parts of water; the pesticide is prepared from the following component raw materials in parts by weight: 30 to 40 parts of nicotine, 10 to 20 parts of chloropicrin, 20 to 30 parts of carbon disulfide and 40 to 60 parts of ethyl alcohol. The method comprises the following steps: fully mixing the shell materials, such as the starch, the bentonite, the gypsum and the water; heating to the temperature of 70 to 90 DEG C; carrying out cooling and preparing into hollow shell; then drying; fully mixing the nicotine, the chloropicrin, the carbon disulfide and the ethyl alcohol of the pesticide; then injecting the pesticide mixture into dried hollow shell pills; sealing needle holes which are formed by injection with the starch to form closed pills; performing vacuum package on the pills. The grain storage anti-insect pesticide is good in insect preventing effect and good in pesticide effect, vaporizes thoroughly, and cannot cause secondary pollution.

Description

Technical field:

[0001] The invention relates to the technical field of insect control medicine production, in particular to a grain storage insect control medicine and a preparation method thereof. Background technique:

[0002] In the prior art, in order to prevent the occurrence of mildew and insects during grain storage, fumigants are often used as insect control agents to kill insects or prevent mold growth, and fumigants are generally divided into solid fumigants. Fumigants, liquid fumigants and gas fumigants are generally used as solid fumigants in grain storage, but the evaporation of solid fumigants is not obvious, there are fewer types, the effect of insect control is poor, the evaporation is not thorough enough, and the residue is easy to cause Secondary pollution. Invention content:

[0003] The technical problem to be solved by the present invention is to provide an anti-insect agent for grain storage with good insect-proof effect, good efficacy, complete eva...
