Compounded seed-coating agent containing phenazine-1-carboxylic acid

Abstract

The invention discloses a compounded seed-coating agent containing phenazine-1-carboxylic acid, the active ingredients of which are thifluzamide, phenazine-1-carboxylic acid and thiamethoxam, and theweight ratio of thifluzamide, phenazine-1-carboxylic acid and thiamethoxam is (1-30):(0.1-5):(10-30). The effect of the seed-coating agent disclosed by the invention is remarkable; compared with thifluzamide or phenazine-1-carboxylic acid, the compounded seed-coating agent is low in dosage and cost and enhances the effect of disease prevention and treatment; and after being mixed with thiamethoxam, the compounded seed-coating agent enhances the pesticidal effect. Moreover, the prevention effect is significantly enhanced, the compounded seed-coating agent is safe for field crops, and the disease prevention effect is remarkable. That is, when the compounded seed-coating agent is applied once, soil-borne diseases and pests, such as southern blight, root rot and bacterial wilt, can be prevented and treated, and the compounded seed-coating agent is environmentally friendly, cannot leave residue, and is highly safe for next-stubble crops.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound seed coating agent containing shenzimycin. Background technique [0002] Peanut is one of the four major oil crops in my country, and its output ranks first in the world. It is one of the crops for net foreign exchange earning in my country. In recent years, the planting area has expanded rapidly, which is affected by factors such as climate, variety and cultivation management methods. The occurrence of peanut blight has been increasing year by year, and it has become an important factor restricting the yield and quality of peanuts. Peanut canker sores is caused by Sclerotinia sclerotiorum, a soil-borne fungus that can infect crops, weeds and woody plants, etc., and has a wide range of hosts. Peanut canker sore is a soil-borne disease that commonly occurs in the world, especially in warm and humid areas. The distribution and damage of peanut canker sore are found in peanut p...

AI Technical Summary

Problems solved by technology

At present, the general medicaments that cause the large-scale occurrence of peanut bacterial wilt and bacterial wilt have no preventive and therapeutic effects, and are difficult to eradicate, and occur year after year, resulting in a large-scale reduction in peanut production.

Currently on the market, a single agent of thifuramide is generally used as the main agent. The effect of a single agent on the prevention and treatment of peanut canker sores is average, and it needs multiple doses of medication, which increases the cost of medication and labor; blight ineffective
