Method for preventing and treating coccid of almond

Abstract

The invention relates to the field of pest control technique of forest and fruit industries, and provides a method for controlling almond scale insects. The method comprises the following steps: evenly spraying a defoliant on a crown of an almond tree during a period between the last ten days of September and the first ten days of October, wherein, the defoliant is prepared by diluting 1ml of 40%etephon aqua with 200-300 times of water by volume. In the method, a plant growth regulator is used for reducing the base number of overwintering pests by making use of a habit that second-instar nymphs of the almond scale insects transfer from leaves to branches to live through the winter, thus achieving control on the damages of the almond scale insects, changing the traditional method and a period of controlling the almond scale insects by an insecticide, producing environmental pollution, causing no pesticide resistance of the pests and avoiding mistaken killing of the natural enemies of the pests.

Description

1. Technical field [0001] The invention relates to the prevention and control technology of forest and fruit industry pests, and relates to a method for preventing and controlling almond scale insects. 2. Background technology [0002] The forest and fruit industry has received unprecedented attention in the sustainable development of society and economy, especially the rapid expansion of economic forest planting area in Xinjiang, and the economic, ecological and social benefits have become increasingly obvious. However, fruit diseases and insect pests seriously affect the quality and function of the fruit industry, and have become a major obstacle to the healthy development of the two major systems of the fruit industry and the ecology. [0003] At present, the losses caused by major pests of fruit trees in Xinjiang are often over 20%, and in some areas and years even reach over 90%. According to the 2007 survey and statistics of the Xinjiang Forestry Department, the area ...
