Composition for preventing and treating citrus yellows and Huanglongbing and application of composition

Abstract

The invention discloses a composition for preventing and treating citrus chlorosis and Huanglongbing and an application of the composition. The composition is prepared from the following raw materialsin parts by weight: 50-70 parts of ampicillin, 6-7 parts of sulfaphenazole, 2-4 parts of sulfamethoxazole, 6-8 parts of magnesium stearate, 6-8 parts of mequindox, 8-9 parts of compound amino acid and 10-11 parts of modified starch. According to the composition, through selection of raw materials in a specific ratio, sufficient nutrient substances can be provided for citrus trees, a broad-spectrum bactericidal effect is achieved, the citrus tree vigor can be enhanced, the tree body resistance can be improved, then citrus tree yellows and Huanglongbing are effectively prevented and treated, the effect is remarkable, and the effect taking speed is high.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of citrus yellowing disease and Huanglongbing, in particular to a composition for preventing and treating citrus yellowing disease and Huanglongbing and its application. Background technique [0002] Citrus is a plant belonging to Rutaceae. It likes a warm and humid climate, and its cold resistance is slightly stronger than pomelo, lime, and sweet orange. The Rutaceae Citrus subfamily is distributed between 16° and 37° north latitude; it is a tropical and subtropical evergreen fruit tree (except Hovenia trifoliate), and there are 3 genera used for economic cultivation: Hovenia trifoliate, Citrus, and Kumquat; China and The citrus cultivated in the rest of the world is mainly of the genus Citrus. [0003] However, in the process of citrus cultivation, citrus yellowing disease and Huanglongbing are the main threats in the process of citrus production, and the affected area is expa...

Problems solved by technology

[0006] At present, the usual treatment methods for Huanglongbing are: implement quarantine to protect new disease-free areas; establish Huanglongbing-free nurseries to cultivate disease-free and strong seedlings; timely dig out diseased plants and spray various tenders in winter to prevent psyllids and spread. Renovate the old diseased areas, replant other crops, and rebuild the hospital with disease-free strong seedlings in a few years; however, the above-mentioned treatment methods are all preventive methods, and the therapeutic drugs for citrus with Huanglongbing cannot be cured, but can only achieve relief effect, causing economic losses to fruit growers
