Plant source quick result insecticidal composition and preparation method and application thereof

Abstract

The invention discloses a plant source quick result insecticidal composition and a preparation method and application thereof, and belongs to the plant source insecticidal pesticide technology field. The insecticidal composition is prepared from the following raw materials by weight percentage: 5-25% of matrine, 5-15% of plant type polyoxyethylene ether, 10-25% of alkyl glucosides, 5-30% of d-limonene, 5-15% of micropore starch, 0.05-0.8% of food antiseptics, and 10-69.95% of water. The raw materials and auxiliary materials used in the inventive composition are all derived from degradable pesticides, and do not contain harmful or un-degradable or potentially risky compounds, and chemical pesticides are not added and used. A pesticide effect test shows that the insecticidal rate of the insecticidal composition can reach or approach the level of chemical pesticides; the insecticidal composition has no pesticide harm to the plants and beneficial insects and is widely suitable for production of organic agricultural products such as fruit, vegetables, tea, tobacco leaves, and traditional Chinese medicinal materials or the like and control of injurious insects such as aphids, locusts, loopworms, red spiders, bradysia odoriphages, matrimony vine pyhlloxeras, pear pyhlloxeras, whiteflies, diamondback moths and armyworms.

Description

technical field [0001] The present invention relates to a kind of botanical insecticidal pesticide and its preparation method and application, specifically relates to a kind of composition of matrine, d-limonene, microporous starch, alkyl glucoside, plant type polyoxyethylene ether, food preservative As well as a quick-acting insecticidal composition prepared from water, a preparation method and application thereof. The invention belongs to the technical field of botanical insecticidal pesticides. Background technique [0002] At present, global pesticides are facing five problems: (1) Chemical pesticides, although they have efficient and reliable control effects, have serious residual pollution problems, which are extremely harmful to soil, air, groundwater, rivers, lakes, agricultural products and human health . (2) Biopesticides (including Beauveria bassiana, Bacillus thuringiensis Bt, Metarhizium anisopliae, etc.) have recognized safety and environmental protection cha...

AI Technical Summary

Problems solved by technology

[0002] At present, global pesticides are facing five problems: (1) Chemical pesticides, although they have efficient and reliable control effects, have serious residual pollution problems, which are extremely harmful to soil, air, groundwater, rivers, lakes, agricultural products and human health

(2) Biopesticides (including Beauveria bassiana, Bacillus thuringiensis Bt, Metarhizium anisopliae, etc.) have recognized safety and environmental protection characteristics, but their effects are slow, and it generally takes 4-7 days from infecting insects to causing disease to death. days, the efficacy and level of chemical pesticides cannot be achieved, and it is difficult to control the pests that have occurred. Therefore, farmers are generally unwilling to use

(3) Although botanical pesticides are recognized as easy to degrade, they are also difficult to promote due to their slow insecticidal effect

(4) Controversy over genetically modified insecticide and insect control technology

(5) No matter what kind of pesticide preparations, the dissolution and emulsification of drugs are inseparable from chemical auxiliaries, and the addition ratio is very large, resulting in serious residual pollution

[0025] According to the international novelty search report provided by Shanxi Science and Technology Information Research (a national first-level scientific and technological novelty search unit), it shows: (1) There is no use of matrine, limonene, alkyl glycosides, plant-type polyoxyethylene ether, and microporous starch. (2) There is no report on the use of microporous starch to solve the easy oxidation and loss of limonene; (3) There are no reports of alkyl glycosides and d-limonene assisting matrine to quickly enter the body of insects to produce quick-acting effects (4) There is no report on the combination of degradable plant-derived emulsifier and high-pressure homogeneous emulsification process to reduce the amount of adjuvants and eliminate pesticide residues
