摘要: 结合云南省凤庆县茶园假眼小绿叶蝉[Empoasca vitis (Gothe)]的全年动态监测,采用4种绿色防控模式对茶园假眼小绿叶蝉防控效果展开研究,并进行成本核算。分别在6月16日、6月24日、7月22日假眼小绿叶蝉发生的3个高峰期用2次植物源生物农药及1次化学农药进行防控。结果表明,综合3次用药的防控效果以及经济效益,推荐最佳防控模式为修剪+石硫合剂封园+蓝板+生物农药(0.6%鱼藤酮450倍稀释液)+化学农药(6%乙基多杀霉素1 000倍稀释液),在该模式的防控下3次药后7 d平均校正防效分别为78.85%、64.650%、76.20%,比常规防治分别增加25.11、41.63、22.68个百分点,产值比常规防治增加2 100元/hm2,产投比为14.6。

Abstract: Combined with the annual dynamic monitoring of Empoasca vitis (Gothe) in tea garden of Fengqing county of Yunnan province, four green prevention and control modes were used to study the prevention and control effect of Empoasca vitis (Gothe) in tea garden, and the cost was calculated. Two times of botanical biological pesticides and one time of chemical pesticides were used to prevent and control the Empoasca vitis (Gothe) in tea garden on June 16, June 24 and July 22, respectively. The results showed that the prevention and control model was pruning + stone sulfur mixture garden sealing+blue board+biological pesticide (450 times dilution of 0.6% rotenone)+chemical pesticide (1 000 times dilution of 6% ethyl doxycycline). Under this mode of control, the average correction control effect of 7 days after three times of treatment were 78.85%, 64.650% and 76.20%, respectively, and which increased by 25.11, 41.63 and 22.68 percentage points compared with conventional control, respectively. Compared with conventional control, the output value increased by 2 100 yuan/hm2, and the ratio of output to investment was 14.6.
