The control effects of 450 mL / hm 2 24% Chlorfenapyr SC and 330 mL / hm 2 15% Indoxacarb were significantly higher than that of 450 g / hm 2 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 occurrence characteristics of E. vitis,and preliminarily summarized the main control methods in recent years. Therefore,from pollution-free and green control perspective,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
