Problems solved by technology

However, the current storage conditions in our country are poor, and the equipment and technology are backward. Especially, it takes a long time for the grain to be stored in the warehouse, and the time to mix the grain while entering the warehouse may be as long as 1 to 2 months; , but the permeability is poor, and the fumigation effect is not obvious; the pirimiphos-methyl powder technology is not suitable for the control of storage pests in my country

Embodiment 1

[0024] Embodiment 1: according to following formula:

[0025] Pirimiphos-methyl 100 parts

[0026] Emulsifier (polyvinyl chloride castor oil) 120 parts

[0027] Stabilizer (epoxidized soybean oil) 50 parts

[0028] Biothrin 2 parts

[0029] 728 parts of water

[0030] A water emulsion of pirimiphos-methyl was prepared. The pesticide for storage of agricultural products is gasified and used for pest control in warehouses. The concentration of pirimiphos-methyl is 2.0 ppm. After 48 hours of spraying, the mortality rate of the pests reaches 99.9%.

Embodiment 2

[0032] Pirimiphos-methyl 100 parts

[0033] Emulsifier (glycerin fatty acid ester) 25 parts

[0034] Stabilizer (epoxidized soybean oil) 15 parts

[0035] Biothrin 0.5 parts

[0036] 250 parts of water

[0037] A water emulsion of pirimiphos-methyl was prepared. The pesticide for storage of agricultural products is gasified and then used for pest control in warehouses. The concentration of pirimiphos-methyl is 1.5 ppm. After 48 hours of spraying, the mortality rate of the pests reaches 99%.

Embodiment 3

[0039] Pirimiphos-methyl 100 parts

[0040] Emulsifier (polyvinyl chloride castor oil: glycerin fatty acid ester = 1: 1) 150 parts

[0041] Stabilizer (epoxidized soybean oil) 75 parts

[0042] Biothrin 2.5 parts

[0043] 1000 parts of water

[0044] A water emulsion of pirimiphos-methyl was prepared. The agricultural product storage insecticide is gasified and used for pest control in warehouses. The concentration of pirimiphos-methyl is 1.0 ppm. After 24 hours of spraying, the mortality rate of the pests reaches 96%.

Abstract

The invention discloses an agricultural products storage insecticide and its production method and use, which is the emulsifying agent of methylpyrimitate or aqueous emulsion of methylpyrimitate. The advantages include high performance, broad spectrum, low toxicity, low residual, and environmental protection. The insecticide is suitable for the prevention and cure of grain and agricultural product warehouse insects.

Description

technical field [0001] The invention relates to a storage pest control insecticide, a production method and application thereof. Background technique [0002] In my country, about 90% of storage pest control methods for grain and other agricultural products are fumigated by the highly toxic pesticide phosphine to ensure storage safety. Partial disinfection of empty warehouses and storage of small batches of agricultural products use dichlorvos and other pesticides to control pests to ensure storage safety. The single method of phosphine fumigation to control storage pests has been used continuously for more than 40 years. With the passage of time, the problems caused by the long-term use of phosphine have become more and more prominent: first, phosphine is a highly toxic pesticide, which has adverse effects on the safety of household products and environmental pollution, and can cause fumigation personnel Chromosomal aberration and carcinogenicity; second, it is flammable,...
