Ligularia virgaurea powder composite granule as well as preparation method and application thereof

Abstract

The invention provides ligularia virgaurea powder composite granules as well as a preparation method and an application technology thereof. The ligularia virgaurea powder composite granule is prepared from 70%-85% of effective active ingredients and 15%-30% of auxiliaries. The main effective active ingredients are micronized by using a superfine powder technology, and then are prepared into granules by using a modern granulation technology. The insecticidal composition is mainly used for preventing and controlling coleoptera, lepidoptera, orthoptera and diptera underground pests such as grubs, wireworms, cutworm mole crickets and root maggots, and also preventing plant diseases caused by pathogenic bacteria such as pathogenic fusarium, phytophthora, rhizoctonia solani and lauraceae. The method is suitable for a modern large-scale mechanical planting production mode; the pesticide is efficient, multiple in effect and long in lasting period, diseases and insect pests are prevented, and the average prevention and control effect on target diseases and insect pests is 60%-85%; soil is improved, and continuous cropping obstacles can be prevented and controlled; the application target is clear and the control spectrum is wide.

Description

technical field [0001] The invention belongs to the field of biopesticides, and specifically relates to an insecticidal and antibacterial composite granule whose main active ingredients are Liwu powder and Coptis chinensis powder, as well as its preparation method and application technology. Background technique [0002] Since environmental factors such as geological features and climatic conditions have a great impact on the nutrition, quality and yield of agricultural products, agricultural products such as vegetables, grains, fruits, and Chinese medicinal materials all pay attention to regional characteristics. In order to maintain stable production and economic benefits, it is difficult to rationally rotate crops and stubble, coupled with the extensive use of chemical fertilizers and pesticides, the soil ecological environment is deteriorating, and the incidence of underground diseases and insect pests is becoming more and more serious. Fusarium wilt, root rot, blight, b...

AI Technical Summary

Problems solved by technology

However, in order to meet the demand for the prevention and control of underground diseases and insect pests of large-scale characteristic agricultural products, these high-quality biocontrol agents of Ligula spp. ;After the active ingredients are extracted, the plant residues account for more than 80%-90% of the dry weight of the plant raw materials, and there are 3-4 times the volume of the extraction solvent. Harmless treatment is a time-consuming and expensive but inevitable production bottleneck.
