Abstract

The invention discloses novel plant source insecticidal bactericide and a preparation process thereof. The novel plant source insecticidal bactericide is prepared from, by mass, veratrine, matrine, pyrethrin, fructus cnidii, ethanol, lecithin and water. The preparation process includes the following specific preparation steps that veratrum nigrum, radix sophorae flavescentis, pyrethrum carneum and fructus cnidii are taken, subjected to impurity removal, completely cleaned, placed in an oven at the temperature of 40 DEG C to be dried to constant weight, and then smashed into particles, and lecithin is added for vibration and filtration; an ethanol solution is added for extraction, and raw drugs of eratrine, matrine, pyrethrin and fructus cnidii are prepared respectively; ethanol and water are added to the raw drugs, after mixing, settling and filtering are conducted, and the novel plant source insecticidal bactericide is obtained. The novel plant source insecticidal bactericide is a wide-spectrum insecticidal bactericide, and is long in lasting period and remarkable in pesticide effect, the comprehensive prevention effect is 80% or above, a good control effect is achieved on aphids, oulema oryzae, gall mites, chilo suppressalis, tryporyza incertulas, rice planthopper, locusts and the like, environment friendliness is achieved, and no pesticide residue is generated.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel botanical insecticide and fungicide and a preparation process thereof. Background technique [0002] In the process of plant growth, due to the fact that diseases and insect pests are transmitted by nature in many ways, the scope is very wide, the harm is great, and the control is difficult. In order to solve and deal with the above problems, the prior art adopts spraying chemical insecticides and fungicides. Although this method It is simple and quick, but the time limit is short, causing pollution to the environment, and at the same time, it also has varying degrees of impact on plants, resulting in drug residue problems. Aphids, gall mites, negative mud worms on wolfberry, cabbage, cabbage, cauliflower and other cruciferous vegetable cabbage caterpillars, diamondback moths, ape leaf worms, cabbage aphids, wheat red spiders, wheat armyworms, wheat armyw...
