Control Effect of Five Pesticides against Sitodiplosis mosellana in Different Growth Stages of Wheat
摘要
Abstract
Five pesticides were employed to spray on wheat in the tassel period in a field experiment for selecting the optimal pesticide to control Sitodiplosis mosellana. The phoxim and imia-dacloprid were applied in the period before emerge, tassel period, flowering period and tassel period + flowering period of wheat to determine the optimal control period. The results showed that among the 5 different pesticides, 2. 5% imiadacloprid EC got the best effect against Sitodiplosis mosellana and its control effect was up to 89. 45%,followed by 81% phoxim EC and 40% chlorpyrifos EC,of which the control effects respectively reached 74. 50% and 71. 05%. As to different spray periods,two sprays of 2. 5% imiadacloprid EC in the tassel period+ flowering period showed the best effect,up to 95. 64%,followed by one spray of imiadacloprid in the tassel period and two sprays of 81% phoxim EC in tassel period+flowering period. As a balanced control solution considering the effect and the cost,one spray of imiadacloprid in the tassel period of wheat is the first choice for simple and effective control of Sitodiplosis mosellana if it is neatly unearthed; However, when Sitodiplosis mosellana is irregularly unearthed, the phoxim and imiadacloprid could be applied twice in the tassel period + flowering period of wheat.关键词
