Abstract

The invention discloses a compound biological pesticide and application thereof. The compound biological pesticide is prepared from red bisabolane type sesquiterpenoids compounds, such as one or moreof turmeronol A, turmeronol B, 8-hydroxy-ar-turmerone, alpha-curcumene and (+)-(S)-ar-turmerone. Further, the compound biological pesticide also includes at least one of fungicide or insecticide selected from matrine, veratrine, osthole, berberine, azadirachtin, abamectin and rotenone. The compound biological pesticide disclosed by the invention has the advantages of low toxicity, high efficiency,strong selectivity and the like, and also has a relatively good prevention and control effect on diseases and insect pests including downy mildew, gray mold, aphids, plutella xylostella, red spiders,cnaphalocrocis medinalis, whitefly and the like in the aspect of the effect of preventing and controlling powdery mildew; the yield of crops including cucumbers and the like is remarkably improved by10 percent to 50 percent, the dosage of a biological pesticide is effectively reduced, and the environment pollution is alleviated; the compound biological pesticide is friendly to people and environment, and meets the requirements on green agricultural development.

Description

technical field [0001] The invention belongs to the field of preventing and controlling agricultural diseases and insect pests, and relates to a compound biological pesticide and its application. The effective active ingredient of the compound biological pesticide is compounded by bisa alkane-type sesquiterpene compound and other biological pesticides Compound fungicides and insecticides. Background technique [0002] Chemical pesticides are effective in preventing and controlling agricultural pests and diseases, and they can quickly curb the occurrence of pests and diseases. However, they have also caused a series of problems such as pesticide residues, drug resistance, and damage to natural enemies. Therefore, it is urgent to develop safe, high-efficiency, low-toxicity, and low-pollution biopesticides to meet the needs of organic agriculture, green agriculture, and environmental safety. [0003] The bisabolane-type sesquiterpenes involved in the present invention are deri...
