Formula of novel agentia for preventing and treating mango bacterial black spot and preparation method of same

Abstract

The invention discloses a formula of a novel agentia for preventing and treating mango bacterial black spot, and a preparation method of the novel agentia. The formula comprises 1000,000 units of streptomycin sulphate with the concentration of 7.50 mu g / mL, 20% thiediazole copper SC with the concentration of 61.90 mu g / mL, and the ratio is 3:2. The preparation method comprises the following steps: selecting a single bactericide necessary for compounding, preparing a bacterium suspension, and evaluating the antibacterial effect inside a compounding agentia room. Due to the adoption of the agentia prepared according to the formula, the defects that the single agentia is not ideal in prevention effect and single in prevention and treatment spectrum, and a mango bacterial black spot pathogenic bacterium is easy to have medicine resistance are overcome, and not only is the prevention effect good, but also both treatment and protection functions are achieved, the prevention and treatment spectrum is widened, the medicine resistance is delayed, and the prevention and treatment cost is low. A toxic containing medium method is adopted, a plurality of ordinary bactericides are compounded by using a mixing method according to a ratio, the purpose of selecting a compounded agentia with high efficiency, low toxicity and both treatment and protection function is achieved, the mango bacterial black spot is effectively prevented and treated, and meanwhile the medicine resistance of the pathogenic bacterium is delayed.

Description

technical field [0001] The invention belongs to the field of prevention and treatment of mango bacterial black spot, and in particular relates to a new medicament formula and preparation method for preventing and treating mango bacterial black spot. Background technique [0002] Mango (Mangifera indica L.), belonging to the Anacardiaceae plant, is known as the king of tropical fruits because of its unique flavor and rich vitamin C. my country is a big mango producing country in the world. In recent years, the mango planting area has gradually expanded, and the output has steadily increased, reaching several million tons per year, ranking eighth in the world. Mango bacterial black spot (Xanthomonas campestris pv.mangiferaeindicae) is one of the important diseases that seriously affect mango production. The disease occurs in mango growing areas such as Brazil, South Africa, India, and Pakistan. The mango orchards in provinces such as Fujian, Fujian, and Yunnan are seriously d...
