闽·浙部分地区茶叶病虫害及其药剂使用情况调查分析

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。

Investigating and Analysis of Disease and Pest and Its Drug Usage in Some Regions of Fujian and Zhejiang Teas

Objective] The aim was to understand the conditions of disease and pest and its drug usage in some regions of Fujian and Zhejiang teas so as to provide reference for the control of disease and pest in teas. Method ] The general situation including variety, quantity and occur- rence harm period of the teas disease and pest as well as types and dosage forms of pesticides on the chemical control in some regions of Fujian and Zhejiang were investigated. Result] There were many kinds of disease and pest in teas in some regions of Fujian and Zhejiang,and they oc- curred over the whole year,furthermore they showed seasonable population change and damage. In pesticide types,Pyrethroids were used most; the use rate of organophosphorus pesticides declined; and the biological pesticides were used less. In pesticide formulations, EC accounted for over 50% , and next was wet powder, so it needed to guide formulations transformation in production. Conclusion ] The research provides theoretical basis for the development of a new pesticide, the reasonable use of pesticide and suggestion for a comprehensive project to prevent and control the teas disease and pest.
