Problems solved by technology

At present, Chinese medicine is developing rapidly in my country, but the application of Chinese medicine theory to develop insecticides and fungicides for Chinese herbal plants can only be said to be in its infancy. In particular, there are few reports on plant-derived agricultural fungicides, and industrial production is even rarer.

Abstract

The invention relates to a compound botanical agricultural bactericide and a preparation method thereof. The compound botanical agricultural bactericide is mainly prepared from the following plant extracts in part by weight: 1 to 4 parts of plant extract of sessile stemona root, 1 to 4 parts of plant extract of shrubby sophora, 1 to 4 parts of plant extract of common cnidium fruit, 1 to 2 parts of litsea cubeba oil, and 1 to 2 parts of citionella oil. The invention has the characteristics that: the agricultural bactericide has strong selectivity, is safe to people, livestock and natural enemies of pests, and cannot produce pesticide resistance easily, and pollute the environment and the like.

Description

technical field [0001] The invention relates to a pesticide, in particular to a compound botanical agricultural fungicide and its preparation and application method. Background technique [0002] At present, low-toxic chemical pesticides are mainly used for the prevention and control of fungal diseases of crops such as vegetables, fruit trees, tea, garden flowers, pastures, etc., such as powdery mildew, gray mold, anthracnose, etc. These pesticides contain copper, sulfur and other harmful substances of different components. As a result of long-term use of low-toxic chemical pesticides, toxic substances in plants are left, which not only pollutes the ecological environment, but also brings different degrees of harm to human health.
