Application of methyl-jasmonate-containing compound in citrus canker

Abstract

The invention relates to application of a methyl-jasmonate-containing compound in citrus canker. Effective components of the methyl-jasmonate-containing compound are composed of Zhongshengmycin and methyl jasmonate, wherein the weight ratio of Zhongshengmycin to methyl jasmonate is (3-20):1. According to the application of the methyl-jasmonate-containing compound in citrus canker, Zhongshengmycin to methyl jasmonate are compounded according to the specific weight ratio, the methyl-jasmonate-containing compound thus has obvious synergistic effects, the pesticide effect can be significantly improvded, the use amount of the single agent of either Zhongshengmycin or methyl jasmonate is easily reduced, the generation of resistance of bacteria to Zhongshengmycin is delayed, and the life cycle of Zhongshengmycin in antibiotic pesticides is prolonged.

Description

technical field [0001] The invention relates to the application field of agricultural fungicides, in particular to the application of a composition containing methyl jasmonate to citrus canker. Background technique [0002] In recent years, with the increase of citrus varieties planted in Guangxi, the occurrence of canker has become more and more common. There are many measures to prevent and control citrus canker, and chemical control is an important measure. Among the current chemical control agents, the control effect of copper preparation is better, but it is easy to induce mite damage and phytotoxicity, which will affect the quality of fruit. Therefore, it is particularly important to seek high-efficiency, low-toxicity, and safe citrus canker control agents. [0003] Zhongshengmycin, whose English name is: zhongshengmycin, is an N-glycoside antibiotic fungicide with a broad antibacterial spectrum and can resist Gram-positive and negative bacteria, mycobacteria, yeast a...

Problems solved by technology

[0005] In agricultural production, compounding active ingredients with different action mechanisms is a common method to delay disease resistance. Zhongshengmycin and methyl jasmonate have different action mechanisms, and mixing them within a certain proportion has a good effect. Synergistic effect. At present, there are no relevant reports at home and abroad on the combination of Zhongshengmycin and methyl jasmonate for citrus canker.
