Problems solved by technology

At present, the main control measures against canker in the production process of citrus are still spraying chemical agents, but due to the long-term use of chemical drugs, the canker bacteria have developed resistance to various fungicides. At the same time, due to the high-intensity use of pesticides, It has caused a series of problems such as polluting the environment and increasing the cost of farmers' medicines

Abstract

The invention belongs to the technical field of pesticides and relates to a pesticide composition, in particular to a pesticide composition for preventing and treating citrus canker. A pesticide composition for preventing and treating citrus canker, which is composed of aureomycin and Zhongshengmycin as active ingredients, and the mass ratio of the aureomycin and Zhongshengmycin is 1‑50:50 ‑1, the pesticide composition can be prepared into conventional dosage forms in pesticide science such as aqueous emulsion, microemulsion, suspension concentrate, wettable powder or water-dispersible granule, and the control effect on citrus canker is significantly improved compared with a single agent. The pesticide composition of the invention has obvious synergistic effect, can reduce the dosage of pesticides, reduce the control cost, delay the generation of pest resistance and reduce the pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a pesticide composition, in particular to a pesticide composition for preventing and treating citrus canker. Background technique [0002] Citrus is a favorite fruit. With the advancement of high-efficiency agriculture, the rapid development of industrial production and the rapid expansion of planting area have increased the number of pathogenic bacteria of citrus canker in orchards year by year, which has led to the occurrence of citrus canker. Citrus canker can cause canker lesions on treetops, a large number of leaves, deformed fruit peels, and ulcers, which seriously affect the appearance and taste of fruits and lose their edible value. It can also cause field losses and even cause serious damage in the storage and transportation of the fruit. At present, there are no effective control measures and methods for the control of canker citrus canker. At present, the main contro...
