Description

technical field [0001] The invention relates to a Chinese herbal medicine control agent for tea common pests and a preparation method thereof, belonging to the technical field of common crop pest control. Background technique [0002] Tea is a shrub or small tree of the genus Theaceae (Theaceae), with leathery leaves and glabrous twigs; tea contains catechin, cholestenone, caffeine, inositol, folic acid, pantothenic acid and other ingredients, which can improve human health. Tea drinks are also known as "one of the world's three major drinks". [0003] During the growth and development of tea leaves, repeated pruning promotes the continuous germination of new shoots of tea leaves. The young branches and leaves contain rich juice, and the fragrance emitted from tea trees attracts many pests to the tea garden. Pests overwintering on the back of tea leaves, in the center of tea leaves, in the soil of tea gardens, and in the rhizosphere soil of tea trees begin to lay eggs and r...

AI Technical Summary

Problems solved by technology

[0004] Existing tea insect pests generally adopt three ways to prevent and control. The first is to use chemical pesticides, such as: burying carbofuran particles under the soil to prevent and control pests in the land and on the surface, spraying dichlorvos, trichlorfon, dimethoate, Pesticides such as phoxim are used for prevention and control, and chemical pesticides are used, which have quick results and a short cycle, but after repeated use, pests are prone to develop resistance, which is not conducive to subsequent control work. In addition, chemical pesticide residues are serious, and tea production and processing are also difficult The remaining pesticides cannot be completely removed, which will cause great harm to the human body; the second is to use biological pesticides, such as spraying pyrethrins, rotenone, matrine, Bacillus thuringiensis, insect mite, Bidan and other biological insecticides for prevention and control, but Biological pesticides are mostly unilateral, slow to take effect, pests are prone to drug resistance, and the pertinence of insecticide is not strong. Often, several pesticides can kill pests, and the effect is not ideal. In addition, biological pesticides are sensitive to temperature, humidity, light and rain The requirements of external factors such as high temperature and other external factors are extremely high, and it needs to be sprayed under specific temperature and humidity. The preservation is seriously affected by light. If it encounters rain during the spraying process, it is very easy to lose the efficacy and the control effect is poor; Insects, such as: using insecticidal lamps, insect traps, insect trap color plates, sex pheromone traps, etc. to collect and kill pests, the cost is high, the insecticidal range is small, the duration is short, and it cannot be completely cured
