Method for synergistically controlling aleyrodid by encarsia formosa gahan and thiamethoxam

Abstract

The invention discloses a method for synergistically controlling aleyrodid by encarsia formosa gahan and thiamethoxam. The aleyrodid damage is controlled by synchronously releasing Encarsia formosa gahan and using thiamethoxam in a sunlight greenhouse vegetable cultivation process. The method is not only beneficial to the realization of continuously controlling pests such as whitefly and bemisia tabaci by protecting and utilizing encarsia formosa gahan, but also capable of rapidly reducing the population density of the pests such as the whitefly and the bemisia tabaci, good in pest killing effect and capable of realizing the organic unification of biological control and control of non-contact chemical pesticides for vegetable crops.

Description

technical field [0001] The invention relates to a method capable of synchronously utilizing Limadida and thiamethoxam to synergistically control vegetable whitefly in a solar greenhouse, and belongs to the technical field of plant protection. Background technique [0002] At present, it is an indispensable green prevention and control measure to control whitefly, whitefly and other pests by releasing Limadida wasps from the cultivation of vegetables in solar greenhouses. It protects and improves the ecological environment of farmland, does not pollute the environment, is safe for humans and animals, and is beneficial to delay the occurrence and development of insecticide resistance of whitefly and whitefly. Such pests also have the advantages of continuous and long-lasting control. However, there are also defects that the control effect is slow, especially when the population density of whitefly and whitefly is high, it is difficult to quickly reduce the population density,...

AI Technical Summary

Problems solved by technology

However, there is also the defect that the control effect is slow, especially when the population density of whitefly and whitefly is high, it is difficult to quickly reduce the population density, and chemical control must be used to quickly reduce the population density

Because chemical pesticides have a certain killing effect on natural enemies, it is difficult to release natural enemies and use chemical pesticides to control pests at the same time in the cultivation of vegetables in solar greenhouses. That is to say, the existing technology cannot realize the coordinated use of chemical control and releasing natural enemies

[0003] Existing chemical pesticides are mostly used through foliar spraying or root application. The contact between chemical pesticides and vegetable crops will inevitably cause vegetable pesticide residues

That is to say, existing chemical control has the defect that it is difficult to realize the non-contact chemical pesticide control of vegetable crops.
