Plant pesticide, and preparation method thereof

Abstract

The invention discloses a plant pesticide. The plant pesticide is prepared from, by weight, 50 to 100 parts of phytolacca acinosa roxb. fruit, 20 to 30 parts of radix phytolaccae, 20 to 30 parts of rhamnus utilis, 15 to 20 parts of nerium indicum mill., 15 to 20 parts of rhododendron simsii planch., 5 to 10 parts of papaver rhoeas, and 5 to 10 parts of castor oil. The plant pesticide is prepared via combination of phytolacca acinosa roxb. fruit, radix phytolaccae, rhamnus utilis, nerium indicum mill., rhododendron simsii planch., papaver rhoeas, and castor oil, so that the plant pesticide is capable of reducing drug resistance of injurious insects, and killing injurious insects in a short time, and insecticidal range is wide; the plant pesticide is prepared from pure plant materials, so that absorption conversion of the plant pesticide by plants is easily realized, no chemical residue is left on crop products, influence on the environment is low, and the plant pesticide is capable of satisfying green environment protection requirements; and the raw materials are easily available and cheap, so that cost of the plant pesticide is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a plant pesticide and a preparation method thereof. Background technique [0002] Insecticides are mainly used to control agricultural pests and urban sanitation pests. They have a long history of use, a large amount of use, and many varieties. Now with the rapid development of agriculture, pesticides have increased agricultural output, but almost all pesticides will seriously change the biological ecosystem, and most of them are harmful to humans, and others will be concentrated in the food chain. Insecticides can be divided into botanical insecticides and chemically synthesized insecticides according to their sources. Chemically synthesized pesticides have a good control effect on plant diseases and insect pests, but the environmental pollution caused by chemically synthesized pesticides has caused harm to the ecological balance; with the development of society, people pay ...

AI Technical Summary

Problems solved by technology

Chemically synthesized pesticides have a good control effect on plant diseases and insect pests, but the environmental pollution caused by chemically synthesized pesticides has caused harm to the ecological balance; with the development of society, people pay more and more attention to environmental protection. Synthetic pesticides can no longer meet the requirements of human environmental protection; compared with botanical pesticides, they can meet the requirements of human green environmental protection. Botanical pesticides are extracted from natural plants, can be quickly degraded, have no environmental problems, and have high selection It is safe for humans and animals, and it also has the advantages of no resistance, no phytotoxicity, fertilizer effect, stimulating effect on crop growth, and can also treat diseases and insect pests; the patent document No. 200410035776.3 discloses a kind of pokeweed containing Compound plant insecticide, the root of pokeweed mainly used in this invention is used as a raw material. Although it has achieved good results in combination with other materials such as neem, sophora flavescens, bacurata, tobacco leaves, and chamaejasma, there are few types of insecticides, and due to the Due to the excessive use of pesticides, some pests have developed drug resistance, and the pests are slowly mutating. The current insecticides containing pokeweed can no longer meet the insecticidal requirements; the patent application document with application number 201510336307. Peach wolf poison environmental protection insecticide, this invention uses long-time soaking to extract effective substances, the extraction time is long, the loss of effective insecticidal substances in plants is large, resulting in poor efficacy of insecticides
