Problems solved by technology

2. The control spectrum is narrow, and even has obvious selectivity
The toxic components obtained from Euphorbia chamaejasma in Africa are 12-isobutyryl-13-acetyl-20-angelyl phorbol ester (12-isobutyryl-13-acetyl-20-angelyphorbol) (36-16), The toxicity is not strong, the half effective dose of the mouse ear shell test is 2.5 μg / ear, and the duration is also short
[0005] In the prior art, there is no relevant report about Euphorbia chamaejasma as a plant pesticide

Abstract

The invention discloses a plant insecticidal pesticide and belongs to the technical field of agriculture. The plant insecticidal pesticide is prepared from the following raw materials in parts by weight: 1 to 3 parts of radix euphorbiae fischerianae, 80 t 120 parts of water, 0.5 to 0.7 part of soap and 0.4 to 0.6 part of tobacco. A formula of the plant insecticidal pesticide disclosed by the invention can prevent and treat cabbage caterpillar, phaedon brassicae baly, oriental armyworm, brown leaf rust, aphid, red spider mite and the like and has the characteristics of greenness, no pollution,low cost and suitability for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a plant insecticidal pesticide. Background technique [0002] In the long-term process of co-evolution with insects, plants have produced secondary metabolites that defend insects from feeding. The chemical components in plants are very complex. There is often more than one insecticidal active component in a plant, and they are in harmony with each other. They often exhibit very complex interactions with organisms; about 30,000 insecticidal active ingredients are currently known. [0003] Botanical pesticides mainly refer to pesticides developed from secondary metabolites with agricultural biological activity produced by plants, animals, microorganisms, etc. Compared with traditional chemically synthesized pesticides, biologically derived natural product pesticides have the following characteristics: 1. Most biologically derived natural product pesticides are less toxic to mamm...
