Efficacy of Several Botanical Insecticides against Two Pests in Tea Plantation
摘要
Abstract
[Objective] The paper was to study the efficacy of several botanical insecticides against two pests in tea plantation. [ Method] U-sing randomized block design, different concentrations of botanical insecticides were sprayed during the young larvae periods of Ectropis oblique hmpvlina Wehrli and peak periods of Empoasca pirisuga, the reduction rate of insect and control effects were investigated after spraying for 1, 3, 7 and 10 d. [ Result] 7. 5% rotenone EC 800 times had the best control effect against E. Oblique hmpulina, and 0.5% veratridine soluble liquid 800 times had the best control effect against E. Pirisuga. 0. 5% veratridine soluble liquid, 0. 2% Celastrus angulatus Maxim. EC, 0. 3% matrine water agent and 7.5% rotenone EC could be selected for the control of E. Oblique hmpulina; 0.5% veratridine soluble liquid, 0. 2% C. Angulatus Maxim. EC, 0. 3% azadirachtin EC, 0. 3% matrine water agent and 7.5% rotenone EC could be selected for the control of E. Pirisuga, of which 0. 3% azadirachtin EC 600 times was the best on sustainable control effect against E. Pirisuga with control efficacy of 100% after 7 d. [ Conclusion] The results provided basis for application of botanical insecticides in pests control in tea plantation.关键词
