In this study, six kinds of chemical pesticides, biological pesticides,microbial pesticides, botanical pesticides and potassium dihydrogen phosphate were selected to optimize the combination, combined with physical trapping of insect traps and pheromones. The control effects was studied on the diseases and insect pests such as Guignardia camelliae, Pestalotiopsis theae, Tea bud blight, Empoasca flavescens, Empoasca vitis, Dendrothrips minowai Priesner, Scirtotuthrips dorsalis and freeze injury were studied. The results showed that In late August and early September, four formulations such as 6% kasugamycin WP 50 g + 0.5% azadirachtin EC 60 mL + 99% potassium dihydrogen phosphate 100 g, 10 billion spores·g^-1+bacillus subtilis WP 50 g + 8 000 IU/μL bacillus thuringiensis SC 80 mL + 99% potassium dihydrogen phosphate 100 g, 6% kasugamycin WP 50 g + 5% high-performance cyhalothrin ME 25 mL + 99% potassium dihydrogen phosphate 100 g, 430 g/L tebuconazole SC 10 mL + 4.5% high-efficiency cypermethrin permethrin EC 25 mL + 99% potassium dihydrogen phosphate 100 g were used. The tea garden was sprayed with 50 kg of water per acre, and the severe disease and pest tea garden was added in the middle of September. In early March of next year, 6% Kasugamycin WP 50 g + 99% potassium dihydrogen phosphate 100 g + water 50 kg spray were used for 1 time for each acre. The pheromone physical trap can effectively control the tea garden insect pest and the freeze injury. Among them, 430 g/L tebuconazole SC 10 mL + 4.5% high-efficiency cypermethrin permethrin EC 25 mL + 99% potassium dihydrogen phosphate 100 g had the best control effect and the highest yield increase rate.
