Application of Isocyanuric Acid in Controlling Corn Top Rot

Abstract

The present invention relates to applications of isocyanuric acid in prevention and control of corn top rot. According to the present invention, isocyanuric acid comprises chlorinated isocyanuric acid and chlorobromoisocyanuric acid, the chlorinated isocyanuric acid is dichloroisocyanuric acid, trichloroisocyanuric acid, potassium salts and sodium salts thereof, and the like; the isocyanuric acid can provide strong resistance induction activity for crops, such that corn top rot can be prevented and controlled by inducing the base resistance; the foliar spraying of 50-2000 ppm isocyanuric acid is separately performed, or is combined with the soluble fertilizer containing plant nutrition, or is combined with pesticides so as to provide the significant corn top rot prevention and control effects.

Description

technical field [0001] The invention relates to a new application of isocyanuric acid, in particular to the application of isocyanuric acid in preventing and treating corn top rot. Background technique [0002] Corn top rot is a new disease of corn, which can be divided into bacterial infection, fungal infection and mixed infection of fungi and bacteria in terms of symptoms. Symptoms of maize top rot are complex and diverse, and can infect and develop diseases throughout the entire growth period of maize. At the seedling stage, the plants grow slowly, the edges of the leaves lose chlorosis, yellow streaks appear, the leaves are deformed, shrunk or twisted, and the seriously diseased plants wither or die; in the middle and late stages of growth, the leaves show that the bases are rotten, only the main veins remain, and the middle and upper parts are intact but Many deformities, the top of the epigenetic new leaves rot, resulting in short leaves, dead or incomplete leaf tips,...

AI Technical Summary

Problems solved by technology

[0003] At present, there are few studies on corn top rot at home and abroad, lack of systematic research and effective control measures, the pathogenesis is unknown, and it is difficult to control. Fungal agents such as carbendazim, chlorothalonil, kasugamycin, yebuconazole, hymexazol, etc., or a mixture of bactericides and fungicides for symptomatic treatment, and a single agent of chlorobromoisocyanuric acid to prevent corn top rot There are no satisfactory control effects in the reports of the disease

Through many years of research on the pathogenesis, the inventor classified corn top rot from a pathogenic disease to an environmental stress disease for the first time in China, and by inducing basic resistance, improving disease resistance and environmental stress resistance of diseased plants, slowing down and eliminating The allergy caused by pathogenic bacteria, prevention and control of the occurrence and development of corn top rot is a new discovery in the study of the pathogenesis of corn top rot and the research of control agents, and there have been no related reports at home and abroad
