Problems solved by technology

The mildew spots are scattered separately in the early stage, and then combined to form a large mildew spot, which can even cover the whole leaf, seriously affecting photosynthesis, disturbing normal metabolism, causing premature aging, and loss of yield
[0005] In the prior art, there is no relevant report about the use of the extracts of Sophora japonica and Nitraria japonica for the prevention and treatment of crop powdery mildew

Abstract

The invention relates to a pesticide composition containing sophora alopecuroide and vetchleaf sophora root extract as well as a preparation method and application thereof and belongs to the field of pesticides. Aiming at solving the technical problems, the invention provides the pesticide composition containing the sophora alopecuroide and vetchleaf sophora root extract. According to the pesticide composition containing the sophora alopecuroide and vetchleaf sophora root extract, active ingredients are obtained by extracting the following raw medicinal materials in parts by weight: 10-30 parts of sophora alopecuroide and 1 part of vetchleaf sophora root. The common sophora alopecuroide and vetchleaf sophora root extract has a synergistic interaction effect and obvious prevention and treatment effects on crop powdery mildew; the sophora alopecuroide and the vetchleaf sophora root can be commonly extracted so that the content of sophoridine, sophocarpidine and other sterilization active components of which main groups are the same as those of sophoridine and sophocarpidine is improved; the powdery mildew is prevented and treated, the immune system capability of crops can be improved, and the activity can be remarkably improved; Chinese herbal medicines are used as the raw materials so that a pesticide residual problem does not exist; compared with a manner of singly using a chemical source pesticide, the pesticide composition is environmentally friendly; and the effective concentration is low when the pesticide composition is used and the cost is low.

Description

technical field [0001] The invention relates to a pesticide composition containing extracts of Sophora sophorae and Nitraria japonica and its preparation method and application, belonging to the field of pesticides. Background technique [0002] Bitter bean is a plant of the genus Sophora in the family Fabaceae, and it is also known as West bean root, bitter licorice, and bitter bean grass. Bitter bean is a perennial herb, the whole plant is densely covered with off-white silky hairs. Because its roots, stems, leaves and fruits are rich in alkaloids, mainly matrine, oxymatrine, sophocarpine, sophoramine and wild indigo, Sophora sophora has high medicinal value. [0003] White thorn flower, the name of traditional Chinese medicine; it is the root, leaf, flower, fruit and seed of the leguminous Sophora genus white thorn flower. [0004] Powdery mildew can occur from seedlings to earing; it mainly damages wheat leaves, but also stems and ears; it starts to produce small yello...
