The control effects of 450 mL/hm2 24% Chlorfenapyr SC and 330 mL/hm2 15% Indoxacarb were significantly higher than that of 450 g/hm2 10% Imidacloprid WP ,which were ideal pesticides against E. vitis and could be popularized and applied in large area.展开更多

This paper described the morphological features, damage modes and occur- rence characteristics of E. vitis, and preliminarily summarized the main control methods in recent years. Therefore, from pollution-free and green control perspec- tive, controlling population quantity of E. vitis safely and effectively and reducing the yield loss of tea has become a hot issue in prevention and control of insect pests in tea garden. The paper provided a reference in green comprehensive prevention of insect pests in tea garden.展开更多
