Guide tea farmers to take comprehensive measures to prevent and treat tea pests and diseases, control pesticide residue pollution in tea products, and provide pollution-free high-quality tea to the market. Our province has issued the "Italian Pest Integrated Disease Prevention and Control (ipm) Technical Regulations" of local standards. The main contents are as follows: , technical principles conscientiously implement the "prevention-based, comprehensive prevention and control" plant protection policy, based on the tea plantation ecosystem, select resistant varieties, implement fitness cultivation, and comprehensively use various measures to make use of tea's own compensation ability and control of natural natural enemies. To improve the tea plantation's ecological environment, priority should be given to biological agents and high-efficiency, low-toxicity, low-residue pharmaceuticals. Pay attention to medication strategies and improve the application of pesticides to ensure the quality of tea is free of pesticides. Second, technical measures (a) agricultural control 1, the species should adapt to local environmental conditions, and the main pests and diseases showed good resistance, and promote the promotion of robust and qualified clones. 2, tea plantations: promotion of shade nets and greenhouse cultivation. When introduced to the outside, no dangerous pests that have not yet occurred in the area may be brought into the seedlings. 3. Picking in a timely manner: To promote mechanized picking and control the pests that inhabit the surface of the tea tree, such as the false eyelid leafhopper, leafhopper, and some budding leaf diseases. 4, reasonable pruning: pruning can cultivate the crown, but also change the living environment of the pest, play a good preventive effect. Such as the reasonable control of tea height, can significantly reduce the harm of poison moth pests; after the spring crown can be reconstructed, can reduce the long-term white plague, black locust whitefly harm; light pruning at the end of autumn can significantly reduce the winter wolfberry leaf base and so on. 5, tea plantation ploughing: combined with basal fertilizer at the end of the autumn, ploughing the tea garden, can reduce the occurrence of elephants in the following year, the lepidoptera pests in the soil in the winter have a better control effect. 6. Clearing the garden in time: At the end of autumn, the deciduous and topsoil near the rhizosphere of the tea plantation are cleared to the deep burial line, which can effectively reduce the incidence of leaf diseases and overwintering pests in the soil. (B) physical control 1, light trapping: the use of insect phototaxis, in the adult stage of its occurrence, the field lighting trapping, reducing the amount of field production. 2. Manual killing: The use of artificial killing and mitigation of harmful effects on pests that are lighter, have obvious hazards to the center, and are suspended animation. 3, promote the use of mechanical or artificial methods to prevent weeds in tea gardens. (C) Biological control 1. Protect and utilize the main beneficial organisms and dominant populations in local tea gardens. 2. Promote the use of biological pesticides such as avermectin, bt, and nuclear polyhedrosis virus. (IV) Chemical control 1. Strengthen the monitoring and reporting of tea pests and diseases, and timely grasp the occurrence of pests and diseases. 2, according to prevention and control indicators (see Table 1), strictly control the appropriate period of application of pesticides. 3, improve the application of technology. To promote low-volume sprays, general pests face insects, the implementation of Pengchao spray; tea in the lower part of the pests, to promote effective lateral low-volume spray. 4. Restricted use of high-efficiency, low-toxicity, low-residue pesticides, control of the use of broad-spectrum insecticides, and reduction of the number of pesticide injections in tea plantations. 5. Strict implementation of relevant national and provincial regulations prohibits the use of highly toxic, high-residue pesticides and their compounding agents. 6, strictly in accordance with the requirements of gb4285, gb8321 control the amount of application and safety interval.
