Abstract

The invention discloses a method for preventing and treating loquat gray spot. A microcapsule bactericide is prepared from plant-derived extract and a conventional bactericide. The microcapsule bactericide is prepared from 15-25% by mass of plant-derived extract, 10-20% by mass of mancozeb, 10-15% by mass of myclobutanil, 5-12% by mass of methyl 2-benzimidazolecarbamate, 0.6-1% by mass of a surfactant, 0.3-0.5% by mass of a stabilizing agent and the balance water. The plant-derived extract bactericide comprises, by weight, 20-30 parts of herba polygoni avicularis, 10-20 parts of Solanum nigrum L., 10-15 parts of sweet wormwood, 5-10 parts of pine needle oil and 2-4 parts of stellera chameajasme. Through use of a microcapsule form, incompatible components are uniformly mixed so that component synergism is improved. Through overall consideration of a relationship of plant materials as monarch, minister, assistant and guide, effects of preventing and treating loquat gray spot are obviously improved and integrated prevention and treatment efficiency is 90% or more.

Description

technical field [0001] The invention relates to the prevention and treatment of loquat diseases, in particular to a method for preventing and treating loquat gray spot disease. Background technique [0002] Compared with traditional chemical pesticides, botanical pesticides have the advantages of easy availability of raw materials, more action sites, less resistance to pests, easy degradation, low residue, less harm to natural enemies and insects, and environmental safety. Screening highly active substances from natural products, using them as templates to synthesize new chemical pesticides, or directly developing them into natural-source pesticide preparations with high efficiency, low toxicity, low residue, and harmony with the environment has become an important step in the creation of new pesticides. One of the effective ways is the development direction of pesticides in the future. [0003] Loquat gray spot disease affects leaves, branches and fruits, and there are two...
