Liquid agent for preventing and controlling wilt diseases, preparation method and use thereof

Abstract

The invention discloses a liquid agent for preventing and controlling wilt diseases, a preparation method thereof and use thereof, and the liquid agent comprises the following components by weight: 0.3-0.8 parts by weight of 25% to 70% carbendazim, 1.0 to 2.0 parts by weight of a 3 % to 7% organic solvent aqueous solution, 0.2 to 0.8 part by weight of a 0.2% to 0.5% plant disease resistance inductor aqueous solution and 100 to 150 parts by weight of water. The preparation method of the liquid agent comprises the following steps: dissolving the carbendazim in the organic solvent aqueous solution, soaking, diluting with water, adding the plant disease resistance inductor aqueous solution, and mixing evenly to obtain the liquid agent for preventing and controlling the wilt diseases. The invention also discloses the use of the liquid agent in preparing a wilt disease control agent for plants. The liquid agent for controlling the wilt diseases is used for controlling melon wilt, can promoteplant growth and improve plant stress resistance, can also control the wilt diseases of various crops such as strawberries, solanaceae vegetables and cotton, and has a wide application range, large application value, and very significant economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of biological control of plant diseases, in particular to a liquid for preventing and treating fusarium wilt, a preparation method and an application thereof. Background technique [0002] Fusarium wilt, also known as wilting disease or wilting disease, is a plant disease caused by fungi or bacteria. Its onset is sudden, and symptoms include severe spotting, wilting, or death of leaves, flowers, fruits, stems, or the entire plant. Rapidly growing young tissues are often attacked. Most commercially important crops are affected by one or more diseases. Blight can affect flowers, leaves, bud bags, seedlings, twigs, stems (vines) and top tips. The host range of fusarium wilt pathogen is: (1) Economic crops: cotton, tung tree, castor, flax, etc.; (2) Solanaceae plants: tomato, pepper, eggplant, tobacco, potato, etc.; (3) Melon crops: cucumber , zucchini, winter melon, watermelon, pumpkin, zucchini, melon, loof...

AI Technical Summary

Problems solved by technology

The long-term and frequent use of chemical agents will lead to the emergence of drug resistance of pathogenic bacteria, leading to unsatisfactory control effects, and excessive pesticide residues in agricultural products and rampant harmful organisms, and also cause serious social problems such as environmental pollution and ecological imbalance.

Conventional chemical methods can control fusarium wilt to a certain extent, but their high cost, poor effect, high pesticide toxicity, high residue, and environmental pollution limit their widespread promotion.

Biological control has low cost, no environmental pollution, and has broad prospects. At present, the biological control bacteria for crop wilt are mainly bacteria, which have poor control stability. Practical applications are limited
