Prevention of pest-free tea pests without pesticides
The technology aims to solve the problems of large blindness in the current tea plantation pest control, large pesticide application amount, high tea pesticide residues, and serious ecological destruction of tea plant insects. Its technical characteristics are: taking the secondary continuous control of tea leafhoppers as the baseline, and using the virus preparations of several major leaf pests as the main body, properly applying effective agricultural measures to control pests in the tea plantation, thereby effectively reducing the use of pesticides. Times and dosage. The specific approach is: use of high-efficiency pesticides during the stop period of the winter season, to prevent and control the small green leafhoppers, reduce their wintering base, and eliminate the need for chemical control until the end of June of the following year to ensure that there is no pesticide residue in spring tea; summer and autumn During the period, the second leaf of the small green leafhopper is protected against other pests, and different virus preparations are used for tea caterpillars, tea leaf roller moths, and tea leafhoppers. The number of times each year can be controlled at about 4 times, which is 3 times less than conventional control. Times. Since 1993, the technology has been promoted to 640000 mu in Xianning, Yichang, Enshi and other places in Hubei Province. Compared with conventional prevention and control, the input is 20 yuan less per acre, the proportion of high quality tea is increased by 10%, and the average increase in income is 50 yuan per mu. The ecological environment tends to a virtuous circle.
