Problems solved by technology

[0003] At present, the control of hawthorn spider mite mainly uses chemical pesticides for spraying, but the long-term and unreasonable use of pesticides not only causes environmental pollution, but also causes harmful mites to become rampant again, and can make harmful mites develop resistance to pesticides and reduce their resistance to drugs. Sensitivity; In addition, spraying a large amount of chemical pesticides will also cause fruit pesticide residues to exceed the standard, affecting the health of eaters

Abstract

The invention discloses a biopesticide composition for preventing and controlling tetranychus urticae, and relates to the technical field of pest mite biopesticide prevention and control. The biopesticide composition comprises a component A and a component B, wherein the component A is prepared from bacillus thuringiensis, mineral oil and eugenol; the component B is prepared from radix stemonae, rhizoma chuanxiong, radix sophorae flavescentis, cortex dictamni, rumex japonicus roots and radix euphorbiae lantu. Microbial source pesticide, mineral source pesticide and botanical pesticide are combined for controlling tetranychus urticae. Compared with the existing chemical pesticide, the biopesticide composition not only has a better control effect, but also does not generate toxic effects onnatural enemies such as orius minutus, chrysopa septempunctata, ladybugs and predatory mites of the tetranychus urticae and does not cause pesticide residues on fruits and harm human health and can also reduce pollution to water environment and soil environment near an orchard.

Description

technical field [0001] The invention relates to the technical field of biopesticide control of pest mites, in particular to a biopesticide composition for preventing and treating Tetranychus hawthorn and its preparation method and application. Background technique [0002] Hawthorn spider mite belongs to Arachnida, Eucaridae, Tetranychiidae, Tetranychidae, commonly known as hawthorn spider mite, is an important pest of pome fruit and stone fruit fruit trees, and its host plants are very wide, including hawthorn, apple, Sand fruit, apricot, peach, pear, plum, crabapple, cherry, oak, etc. Rosaceae fruit trees suffered the most. Hawthorn spider mites have the habit of spinning silk and pulling nets, mainly harming leaves, young shoots and calyx, destroying stomatal structure, palisade tissue and chloroplast, causing abnormal physiological performance of the tree body, affecting yield, and in severe cases affecting flower bud differentiation and yield in the next year . Tetran...
