Abstract

The invention relates to a pesticide composition containing extracts of cymbopogon distans and raw gingers and a preparation method and application thereof, belongs to the field of pesticides, and provides the pesticide composition containing the extracts of the cymbopogon distans and the raw gingers in order to solve the technical problem. Active components of the pesticide composition containing the extracts of the cymbopogon distans and the raw gingers are extracted from the following raw medicinal materials in parts by weight: 10 to 30 parts of cymbopogon distans and 1 part of raw gingers. The common extracts of the cymbopogon distans and the raw gingers have a synergistic effect, and the effect of preventing and treating leaf mould of crops is obvious; by the adoption of the cymbopogon distans and the raw gingers for joint extraction, the contents of nerol, gingerol and other bacterial active components with main genes basically the same as those in the scoparone and the leaf rheum emodin are increased; the leaf mould is prevented and treated, the immunity system of the crops can be improved, and the activity of the crops can be obviously enhanced; traditional Chinese herbs are used as raw materials, so that pesticide residues are avoided; compared with an independently used chemical-source pesticide, the pesticide composition is environment-friendly; meanwhile, when the pesticide composition is used, the effective concentration is low, and the cost is low.

Description

technical field [0001] The invention relates to a pesticide composition containing rue and ginger extracts, a preparation method and application thereof, and belongs to the field of pesticides. Background technique [0002] Rue is the whole plant of Gramineae Rue Cymbopogondistans (Nees) Wats. . [0003] Ginger is the fresh rhizome of ginger (Zingiberofficinale Roscoe), a perennial herb of the Zingiberaceae family, with a height of 40-100cm. Aliases include ginger root, Bailayun, Gouzhuangzhi, Yindixin, Yanliang boy, fresh ginger, and honey-roasted ginger.
