Problems solved by technology

However, there are high pollution and high residual risks
Although it has played an extremely important role in the control of rice sheath blight, as people pay more and more attention to the environment and food safety, traditional pesticides are facing the situation of being eliminated

preparation example Construction

[0038] Preferably, the preparation method of the pesticide also includes: adding the active ingredient of the pesticide to an auxiliary agent, and the auxiliary agent is at least one of emulsifiers, antifreeze agents, solvents, defoamers, wetting agents, and stabilizers. A method of forming pesticide preparations for preventing and controlling fungi;

[0039] The emulsifier is at least one of a nonionic surfactant and an anionic surfactant;

[0040] The antifreeze agent is at least one of glycerin, propylene glycol, ethylene glycol, sodium chloride, calcium chloride, and sorbitol;

[0041] The solvent is at least one of water, ethanol, isopropanol, n-butanol, ethyl acetate, butyl acetate, dimethylsulfoxide, turpentine, solvent naphtha, N-methylpyrrolidone, and dimethylformamide ;

[0042] Described defoamer is organosilicon defoamer;

[0043] The wetting agent is alkyl sulfate, alkylbenzene sulfonate, alkyl naphthalene sulfonate, fatty alcohol polyoxyethylene ether, alkylph...

Embodiment 1

[0056] Take 600g of the whole plant of bitter kudzu and 100g of the whole plant of Zi Hui Huai.

[0057] After mixing bitter kudzu and purple locust tree, adding 4200g of absolute ethanol, refluxing twice at 80°C for 2 hours each time to obtain an extract; combining the two extracts, filtering, and concentrating to obtain the active ingredient of the pesticide; Take 0.125 g of the active ingredient of the prepared pesticide, add 10 g of ethylene glycol, and 15 g of 1601 emulsifier, and mix to obtain a uniform and stable pesticide preparation A1 for preventing and controlling fungi.

Embodiment 2

[0059] Take 100g of the whole plant of bitter kudzu, and 100g of the whole plant of Zi Hui Huai.

[0060] After mixing bitter kudzu and purple locust tree, adding 1200g of absolute ethanol, refluxing twice at 80°C for 2 hours each time to obtain an extract; combining the two extracts, filtering, and concentrating to obtain the active ingredient of the pesticide; Take 0.125 g of the active ingredient of the prepared pesticide, add 10 g of ethylene glycol, and 15 g of 1601 emulsifier, and mix to obtain a uniform and stable pesticide preparation A2 for preventing and controlling fungi.

Abstract

The invention relates to a fungus controlling pesticide and a production method thereof, in particular to the fungus controlling pesticide produced with omei mountain kudzuvine roots and amorpha fruticosa and the production method thereof, and belongs to the technical field of pesticides. Active ingredients of the fungus controlling pesticide produced with the omei mountain kudzuvine roots and theamorpha fruticosa are prepared from, by weight, 1-10 parts of the omei mountain kudzuvine roots and 1 part of the amorpha fruticosa in an extracted mode. According to the fungus controlling pesticideproduced with the omei mountain kudzuvine roots and the amorpha fruticosa, herbaceous plant extracts serve as the active ingredients, pesticide residues for crops are avoided, pollution on the environment can be avoided, the control effect on rice sheath blight controlling is 85% or above, and meanwhile the fungus controlling pesticide has the effects of early-state preventing and treating afterdiseasing on rice blast, rust disease and the like.

Description

technical field [0001] The invention relates to a pesticide for preventing and controlling fungi and a production method thereof, in particular to a pesticide for preventing and controlling fungi produced by bitter kudzu and pagoda chinensis and a production method thereof, and belongs to the technical field of pesticides. Background technique [0002] Rice sheath blight, also known as moire, is commonly known as flower foot stalk, rotten foot blast, eyebrow spot. It is caused by infection by Rhizoctonia solani, and it mostly occurs under high temperature and high humidity conditions. Sheath blight is one of the major diseases in rice production, which is a serious hazard in southern rice areas. Diseases can occur from seedling stage to ear stage. Leaf sheath infection produces small dark green water-soaked blurry spots near the water surface, which gradually expands into oval or moiré shapes, and the middle part is gray-green or gray-brown. Translucent, with dark brown e...
