[目的]了解闽、浙部分地区茶叶病虫害发生情况及药剂的使用情况,为做好适时、及时控制病虫害发生提供参考。[方法]通过实地考察,对福建、浙江部分地区茶园茶叶的病害和虫害的种类、数量、发生为害时期和药剂防治所用农药的种类、剂型的大致情况进行调查及分析。[结果]闽、浙部分地区茶树上常见病虫害种类繁多,发生时间遍及全年,许多茶园病虫害表现出季节性的种群数量变化和危害。农药类型中,拟除虫菊酯类农药使用较多,有机磷农药使用比例下降,生物农药使用较少;农药剂型中,乳油占50%以上,其次是可湿性粉剂,生产中要注意引导剂型转换。[结论]为新农药品种的开发、农药的合理使用及茶叶病虫害综合防治方案的提出提供了理论依据。
[Objective] The research aimed to understand the occurrence of tea plant diseases and insect pests and the use of pesticides in some areas of Fujian and Zhejiang, and provide references for timely and timely control of the occurrence of pests and diseases. [Method] The field investigation was conducted to investigate and analyze the tea plant diseases and insect pests, the types and quantities of tea in some parts of Fujian and Zhejiang provinces, the period of pesticide damage and the types and formulations of pesticides used in pesticide control. [Result] The common pests and diseases on tea trees in Fujian and Zhejiang parts were numerous and occurred throughout the year. Many pests in tea plant showed seasonal changes in population and damage. In the pesticide types, the use of pyrethroid pesticides is more, the proportion of organophosphorus pesticides used is decreased, and the use of biological pesticides is less. In pesticide formulations, emulsifiable oil accounts for more than 50%, followed by wettable powders. [Conclusion] This provided the theoretical basis for the development of new pesticide varieties, the rational use of pesticides and the proposal of integrated pest and disease control programs.
