Problems solved by technology
The control effect of chemical pesticides on tea leafhoppers can reach more than 75%, but a large amount of chemical pesticides will cause the tea garden to be polluted, which is not conducive to the sustainable development of the tea garden
However, the use of biological pesticides to prevent and control tea leafhoppers will not pollute tea gardens, but the control effect on tea leafhoppers is only 45% to 50%.

The invention discloses a metarhizium anisopliae pharmaceutical composition applied to tea garden pest control in the field of pesticide compounding, which comprises metarhizium anisopliae and chlorfenapyr, and 1g of chlorfenapyr is mixed with 9.8*10<10>-1.2*10<11> metarhizium anisopliae. After the metarhizium anisopliae pharmaceutical composition applied to tea garden pest control in the proportion is diluted with water and sprayed to tea trees, tea lesser leafhoppers can be remarkably killed, and the control effect on the tea lesser leafhoppers reaches 80% or above. Besides, due to the use of the metarhizium anisopliae, the use amount of chlorfenapyr is reduced by more than 30%, and the toxicity of the metarhizium anisopliae pharmaceutical composition applied to tea garden pest control is greatly reduced, so that the pollution of the metarhizium anisopliae pharmaceutical composition applied to tea garden pest control to a tea garden is reduced.
Description
technical field [0001] The invention belongs to the field of pesticide compounding, and in particular relates to a drug combination and application of Metarhizium anisopliae of scarab for pest control in tea gardens. Background technique [0002] Tea small green leafhopper is a kind of insect of Hemiptera, Leafhopper family, commonly known as floating dust and leaf collembola; it is one of the main pests of tea gardens. Its adults and nymphs live by sucking the juice of the young buds and leaves of tea trees. The veins of the damaged buds and leaves are red at the beginning, and then the edges are scorched, the buds and leaves shrink, and the growth stagnates; it has a great impact on the yield and quality of tea. [0003] At present, the chemical control method of tea green leafhopper is mainly realized by spraying 40% dimethoate emulsion, 50% fenitrothion emulsion, 1000 times of 50% marathon emulsion or 1400 times of 50% dichlorvos emulsion; or use 0.5% veratrine wettabl...
