Method for preventing and treating thrips through coordination of neoseiulus barkeri and thiamethoxam

Abstract

The invention discloses a method for preventing and treating thrips through coordination of neoseiulus barkeri and thiamethoxam. In a process of culturing vegetables in a daylight green house, damageof the thrips is controlled by simultaneously releasing the neoseiulus barkeri and using the thiamethoxam. According to the method, protection realization and continuous control of the thrips by utilizing the neoseiulus barkeri can be facilitated, the population density of the thrips also can be quickly slowed down, the insecticidal effect is good, and organic unity of biological prevention and control as well as prevention and control of non-contact type chemical pesticides of vegetable crops can be realized.

Description

technical field [0001] The invention relates to a method capable of synchronously using Neoseiidus pasteurii and thiamethoxam to synergistically prevent and treat thrips in solar greenhouse vegetables, and belongs to the technical field of plant protection. Background technique [0002] At present, the release of Neoseiusi mite in solar greenhouse vegetable cultivation to control thrips and other pests is an indispensable green prevention and control measure, which can protect and improve the ecological environment of farmland, does not pollute the environment, is safe for humans and animals, and is conducive to delaying thrips The occurrence and development of insecticide resistance, and in the case of continuous use, it also has the advantages of continuous and long-lasting control of thrips and other pests. But there is also the defect that the control effect is slow, especially when the population density of thrips and other pests is high, it is difficult to quickly redu...

AI Technical Summary

Problems solved by technology

However, there is also the disadvantage that the control effect is slow, especially when the population density of thrips and other pests 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.
