Method for green prevention and control of vegetable red spider

Abstract

The invention discloses a method for green prevention and control of vegetable red spider. The method comprises: (1) preparing agents, wherein the agent A is prepared from the following components by weight: 100 parts of water, 10 parts of tobacco leaf, 1 part of mimosa pudica linn, and 2 parts of brown sugar, and the agent b is prepared from the following components by weight: 80 parts of water, 8 parts of camellia seed, 1 part of mimosa pudica linn, and 2 parts of white sugar; and (2) spraying the agent A at morning and spraying the agent B at dusk, wherein the spraying is continuously performed three times at 8 days interval. According to the present invention, the red spider prevention and control rate of the method can achieve more than 98%, and the method has characteristics of good rapid-effect, long duration, low use cost, no toxicity, and no pollution.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a green method for controlling vegetable red spiders. Background technique [0002] Spider mite is the main pest mite that harms vegetable crops. With global warming and the continuous expansion of protected cultivation areas, especially the cultivation of greenhouse vegetables, it has been given a more suitable breeding environment. High temperature can increase its occurrence base and cause The number of generations increases, and the greenhouse planting becomes a place for a large number of red spiders to overwinter and reproduce in winter. In greenhouse vegetable planting, its natural enemies are often isolated, and the loss of control makes the red spider reproduce more rapidly. Overlapping, multiple control efforts are required in production to be effective. The long-term use of chemical pesticides in large quantities has led to resistance to certain chemical pesticides, and the...

[0002] Spider mite is the main pest mite that harms vegetable crops. With global warming and the continuous expansion of protected cultivation areas, especially the cultivation of greenhouse vegetables, it has been given a more suitable breeding environment. High temperature can increase its occurrence base and cause The number of generations increases, and the greenhouse planting becomes a place for a large number of red spiders to overwinter and reproduce in winter. In greenhouse vegetable planting, its natural enemies are often isolated, and the loss of control makes the red spider reproduce more rapidly. Overlapping, many times of prevention and control are needed in production to be effective. The long-term use of chemical pesticides in large quantities leads to resistance to some chemical pesticides, and the control effect in the field is significantly reduced. At present, spider mite has become an object that is difficult to control in production.
