Comprehensive prevention and control method for tea lesser leafhoppers

Abstract

The invention provides a comprehensive prevention and control method for tea lesser leafhoppers, and belongs to the field of agricultural insect and pest control. According to the comprehensive prevention and control method, five control measures such as insect infestation monitoring, gardening prevention and control, physical prevention and control, biological prevention and control and chemical prevention and control are integrated and assembled for three growth stages such as the first growth stage (spring shoots), the second growth stage (summer shoots) and the third growth stage (autumn shoots) of annual growth periods of tea, and comprehensive prevention and control measures suitable for all growth periods are put forward. According to the comprehensive prevention and control method for the tea lesser leafhoppers, occurrence and damage of the tea lesser leafhoppers can be effectively controlled, the usage frequency and usage amount of pesticides are significantly decreased, and the great significance of increasing the yield of the tea and improving the economic value and planting environment is achieved.

Description

technical field [0001] The invention relates to a comprehensive prevention and control method for the tea leafhopper, belonging to the field of agricultural insect and pest control. Background technique [0002] Tea green leafhoppers generally have 9-12 generations in the south, and the generations overlap. Adults overwinter on tea trees or weeds. The eggs are laid in the cortex of the tender stem, and are mostly produced in the upper stem of the second and third leaves under the bud. It mainly damages the young shoots, buds and leaves of tea trees. There are two peaks of insect population in a normal year. The first peak is in mid-May and mid-to-late July, which mainly harms summer and summer tea. The second peak is from mid to late September to early October, mainly harming autumn tea. According to the occurrence and damage characteristics of the small green leafhopper, green prevention and control should focus on biological prevention and control, based on investigati...

AI Technical Summary

Problems solved by technology

The advantages are convenience, economy, and preventive effect; the disadvantage is that the control effect is poor when the population of insects occurs is large

Physical prevention and control: Use color plates (yellow plates, etc.), attractants and other methods to reduce the damage caused by small green leafhoppers; the advantage is that it does not destroy the ecological balance and does not produce 3R consequences; the disadvantage is that the cost involved is slightly higher

Biological control: use biocontrol bacteria (beauveria bassiana, etc.) and natural enemies (spider, etc.) to control the population of small green leafhoppers; the advantage is to maintain ecological balance, ensure long-term development, not pollute the environment, and not produce 3R consequences; the disadvantage is that it is often affected by Restricted by various conditions such as climate, the control is specific

Chemical control: Use 25% imidacloprid + 25% acetamiprid (
