Abstract

The invention discloses a technique for controlling green plant bug in the Jiangbei tea area, and belongs to the technical field of tea tree pest control. The technique comprises three main steps of sowing peas, spraying a pesticide, and eliminating pea stalks. By intercropping the peas, the green plant bug is attracted; a botanical pesticide is sprayed onto the peas, so that tea plucking is not affected and pesticide residue of a tea garden is not caused; moreover, green peasecods are harvested in the tea garden, and the damage rate of tea shoots from the green plant bug in whole spring is less than 2 percent; and the technique can be widely applied to organic and pollution-free tea gardens in the Jiangbei tea area.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of tea plant diseases and insect pests. Background technique [0002] Lygus green bug is the main pest in Jiangbei tea area in spring. Adults and nymphs prick and suck young tea tree buds and leaves, and small black dead spots appear on the damaged parts, which later become irregular holes as the buds and leaves stretch. The dry tea made from the damaged buds and leaves has low aroma, bland and astringent taste, and the quality drops significantly. [0003] The existing tea plantation pest control technology is to spray chemical pesticides or botanical pesticides on tea trees. Spraying chemical pesticides is likely to cause pesticide residues; although botanical pesticides can be used in organic tea gardens, fresh leaves cannot be picked within a safe interval after spraying, which seriously affects the yield of tea gardens in spring.
