Method for preventing and controlling citrus red mites

Abstract

The invention relates to a method for preventing and controlling citrus red mites. The citrus red mites have strong sitotaxis to oxalis corniculata, and the oxalis corniculata is interplanted in a citrus orchard, so that there is abundant oxalis corniculata in the citrus orchard to attract the citrus red mites to feed off the oxalis corniculata in spring, summer or autumn with high incidence of the citrus red mites, thereby preventing the citrus red mites from feeding off citrus fruits and leaves; when the average number of the citrus red mites on each leaf of the oxalis corniculata is 3 to 5,prevention and control of the citrus red mites can be achieved without spraying pesticides to citrus trees, as long as the oxalis corniculata is sprayed with pesticides to kill the citrus red mites.The oxalis corniculata is interplanted in the citrus orchard, so that soil organic matter is increased to achieve cost savings and optimize an orchard ecological environment, and a technical support for production of green and safe citrus is provided. The method has the advantages of simple operation, easy learning and popularization, stable effects, no toxicity, no side effects, less investment,high benefits and wide application prospects, and is an effective new technology for farmers to get rich.

Description

technical field [0001] The invention relates to a technology for preventing and controlling citrus pests, in particular to a method for preventing and controlling citrus red spiders, belonging to the technical field of plant protection. Background technique [0002] China's citrus planting industry is developing rapidly, and its citrus planting area and output both rank first in the world. With the rapid expansion of citrus planting area, the damage caused by various pests is also increasing. The citrus red spider is one of the most important pests that damage citrus. The citrus red spider has 12 to 20 generations a year, and the generations overlap, which seriously damages citrus. The leaves and fruits of the plant need to be sprayed 4 to 8 times a year to prevent red spider mites, which not only pollutes the environment, but also increases production costs. [0003] If we can invent a method of preventing and controlling citrus trees with less pesticide spraying and preve...
