Abstract

The invention relates to a shenqinmycin-avermectins suspoemulsion used for controlling plant nematodes and a preparation method of the suspoemulsion. The suspoemulsion comprises following components by weight: 1%-10% of shenqinmycin, 0.2%-2% of avermectins, 2%-8% of an emulsifier, 1%-5% of a dispersant, 0.1%-1% of an antisettling agent, 2-10% of an anti-freeze agent, 0.5-2% of a wetting agent and 5%-10% of a solvent, with the balance being water and the sum of the components being 100%. Compared with the prior art, the mixture provided by the invention has a contact-killing function, a stomach toxicity function, an inhibition function for normal growth of phytopathogen hyphae, and a function of causing mycelia breakage, tumidness, deformation and lysis.

Description

technical field [0001] The invention relates to a pesticide, in particular to a shenzamycin-abamectin suspoemulsion for preventing and controlling plant nematodes and a preparation method thereof. Background technique [0002] Biological pesticide Shenzimycin is an agricultural antibiotic secreted by Pseudomonas fluorescens M18, which has the ability to promote plant growth and broad-spectrum inhibit various crop pathogens, through biological fermentation and cultivation. It can effectively control serious damage to fruits, vegetables, Various fungal diseases of rice, wheat, potato and other crops. The mechanism of action of Shenzimycin is mainly to use its redox ability to accumulate active oxygen in fungal cells and inhibit the oxidative phosphorylation of the respiratory transfer chain in mitochondria, thereby inhibiting the normal growth of plant pathogenic mycelium and causing mycelium Fracture, swelling, deformation and cracking. Shenzimycin has remarkable characteri...
