Abstract

The invention discloses a functional foliage fertilizer for preventing and controlling powdery mildew of tomatoes and cucumbers and application. The main raw materials for the foliar fertilizer include a solution of hydrolyzed starch Bacillus amyloliquefaciens YN2010-KC with CGMCC No.5722, other microbial bacterial solutions, a nitrogen source, a phosphorus source, a potassium source, trace element raw materials, humic acid and a stabilizer, and the functional foliage fertilizer is prepared through compounding in proportion. The foliar fertilizer is a novel ecological and safe fertilizer and can be used for foliar application and root irrigation of crops. The prevention and control effect on the powdery mildew of vegetables is high, the prevention and control effect on the powdery mildew of the tomatoes is up to 77.95-92.37%, the prevention and control effect on the powdery mildew of the cucumbers is up to 71.80-81.19%, the functional foliage fertilizer is non-toxic, residual-free, pollution-free and free of toxic and side effects, does not contain any harmful chemical substance, fertilizers can be decreased or neither fertilizer or pesticide is used, an entire ecological system is changed, and high-quality pollution-free agricultural products are produced out.

Description

technical field [0001] The present invention relates to a kind of foliar fertilizer used in agricultural production for preventing and treating powdery mildew, more specifically, it relates to a multifunctional microbial foliar fertilizer used for foliar spraying, which can also be used for root irrigation and belongs to fertilizer technology field. Background technique [0002] Erysiphales are specialized plant pathogenic fungi, belonging to Ascomycotina, Pyrenomycetes, Erysiphales, Erysiphaceae, mostly ectoparasitic, mycelium All or most of them are exposed on the surface of the leaves, stems, shoots, buds, flowers and fruits of the host plant, and produce a large amount of white powdery matter visible to the naked eye consisting of mycelia, conidiophores and conidia. [0003] There are 18 genera and 435 species of powdery mildew in my country, which are various, widely distributed and seriously harmful. After the occurrence of powdery mildew, the growth of the affected ...
