specific Embodiment approach 1

[0009] Specific embodiment one: the soybean disease-resistant fungicide of the present embodiment is carried out according to the following steps: the preparation weight concentration is respectively 5~50% α, 500ml of gamma-diacetyl acetoacetate aqueous solution and 5~50% formyl formate 500ml of ester aqueous solution, mix the above two solutions in the container, seal the container and fill it with nitrogen to remove oxygen for 5-50 minutes, then add 0.04-4 grams of ammonium persulfate, 0.03-3 grams of azobisisobutyronitrile, all closed, placed 60 Irradiate in a Coγ-irradiation room, control the irradiation dose to 0.04-4KGY, and the dose rate is 0.02-2KGY / h, slice, dry, and pulverize after irradiation to obtain methyl diacetylacetate formate.

specific Embodiment approach 2

[0010] Specific embodiment two: the soybean disease-resistant fungicide of the present embodiment is carried out according to the following steps: prepare 40wt.% α, 500ml of γ-diacetyl sodium acetoacetate aqueous solution, 500ml of 40wt.% methyl formate aqueous solution, mix above-mentioned two kinds The solution was mixed in a plastic container, sealed and filled with nitrogen to remove oxygen for 20 minutes, then added 0.4 g of ammonium persulfate and 0.3 g of azobisisobutyronitrile, fully sealed, and placed in 60 Irradiate in a Coγ irradiation room, the irradiation dose is 0.4KGY, and the dose rate is 0.2KGY / h. After irradiation, slice, dry, and pulverize to obtain sodium diacetylacetate methyl formate.

specific Embodiment approach 3

Abstract

The present invention relates to the preparation of bactericide for treating soybean repeating crop disease and the soybean disease resisting seed coating agent and soybean disease resisting spray with the bactericide as material. The soybean disease resisting bactericide is prepared through compounding alpha, gamma-diacetyl acetyl acetate aqua and methyl formate aqua, mixing two kinds of aqua in some container, sealing the container and filling nitrogen to eliminate oxygen, adding ammonium persulfate and azobisisobutylnitrile, sealing, irradiation with Co-60 gamma ray inside radiation chamber, slicing, stoving and crushing. The soybean disease resisting bactericide has high effect on preventing and treating soybean repeating crop disease. The soybean disease resisting seed coating agent is effective in preventing and controlling foot rot, rhizoctonia disease, etc. of treating soybean, and the soybean disease resisting spray is effective in preventing and controlling the rhizoctonia disease.

Description

Technical field: [0001] The invention relates to a preparation method of a fungicide for preventing and controlling soybean stubble disease, and a soybean disease-resistant seed coating agent and a soybean disease-resistant spray agent using the fungicide as raw materials. Background technique: [0002] The three northeastern provinces and the Dongsi League of Inner Mongolia are the main soybean producing areas in China. In recent years, the area of ​​soybeans under heavy cropping has accounted for 60-80% of the soybean area, and some counties and cities have over 90% of the area under heavy cropping. Repeated stubble has caused serious pests and diseases, resulting in a large area and a substantial reduction in production. The reason for the decrease in production is that the soil environment deteriorates due to changes in soybean root exudates, root stubble decomposition, and rhizosphere microorganisms. The deteriorated soil environment is just conducive to the activities ...
