Problems solved by technology

It cannot achieve immediate results like chemical pesticides, and it is difficult for users to adapt; (2) Compared with chemical pesticides, botanical pesticides have relatively low active ingredients. They are relatively affected by the environment, which increases production costs. Marketing is relatively difficult; (3) the current production of botanical pesticides is out of touch with scientific research and development, and the conversion rate of scientific and technological achievements is low, which restricts the industrialization and marketization of botanical pesticides; (4) due to regional differences, climate , season, and place of origin, etc., make the content of insecticidal herbal raw materials the most unstable, with different efficacy, making it difficult to standardize production

Embodiment

[0017] Example: a plant-derived insecticide, composed of 25%-30% of plant extract compound components, 2%-4% of cashew nut shell liquid, 15%-20% of emulsifier, and 100% of solvent supplementation, according to this field Prepared into emulsifiable concentrate dosage form according to internal general method.

[0018] The plant extract compound component is composed of angelica extract, castor oil extract and cnidium extract compounded according to the mass ratio of 2.5:1:1. The angelica extract, castor oil extract, and cnidium extract are ethanol extracts, and the extraction method is: dry the plant material indoors to a certain extent, put it in a constant temperature oven (about 45° C.), and blow it dry until the material becomes dry. Brittle, each sample was crushed with a material grinder, passed through a 60-mesh sieve, put into a plastic sealed bag and stored in a 4°C refrigerator for later use. When in use, take 60g of plant material dry powder and place it in a 1000mL...

Abstract

The invention provides a botanical agricultural insecticide, which is friendly to environment, good in insecticidal efficacy and not easy to generate resistance. A missible oil dosage form is prepared by compounding plant extract compound components, namely cashew nut shell oil, an emulsifier and a solvent. Through compound use of a botanical pesticide and a chemical pesticide, complementary advantages are facilitated; the usage amount of the chemical pesticide can be greatly reduced; the bad effects such as pesticide residue pollution are reduced; the drug resistance of pests is delayed; the use safety of the pesticide is improved; and the development direction of sustainable control on the pests at present is compounded.

Description

technical field [0001] The invention relates to a botanical insecticide, which belongs to the field of agricultural insecticides. Background technique [0002] Chemical pesticides play an important role in the prevention and control of harmful organisms and the growth of agricultural production due to their good efficacy, high use efficiency, and significant economic benefits. However, during the irrational use of chemical pesticides by humans, a series of environmental and social problems have arisen, such as the typical "3R" problem, that is, pest resistance, pesticide residues, and pest re-emergence. In addition, chemical pesticides are also accompanied by chronic toxicity. And the "three-cause" effect, that is, carcinogenic, teratogenic, and mutagenic. As people pay more and more attention to environmental and health issues, it has become a top priority to use safer biopesticides on crops to reduce the use of chemical pesticides. The development of biopesticides with h...
