在复合种植模式下大豆高隆象的发生率远高于其它害虫,成为造成大豆产量损失的重要因素。本研究用防治大豆高隆象的两种药剂处理大豆,检测大豆氧化胁迫损伤,并调查了间作和净作模式下的虫害发生率和药剂防效。结果表明:药剂处理组中,大豆的生长发育受阻,活性氧(ROS)累积量上升,膜脂通透性增加,抗氧化酶活力增强;药剂处理对大豆叶片均造成了氧化胁迫损伤。喷施三唑磷氧化胁迫损伤效应显著低于喷施氯虫苯甲酰胺和复配;间作模式下大豆高隆象的发生率远低于净作,两种模式下,三唑磷对大豆高隆象的防效均比氯虫苯甲酰胺以及两种药剂复配的效果更好。优选三唑磷作为大豆高隆象成虫的防治药剂。
The occurrence rate of Glycyrrhiza glabra in the compound planting mode is much higher than that of other pests and becomes an important factor for the loss of soybean yield. In this study, soybean was treated with two agents against Glyphosate so as to detect the oxidative stress of soybean, and the incidence of pests and pesticide control were investigated. The results showed that the growth and development of soybean were blocked, the accumulation of reactive oxygen species (ROS) increased, the permeability of membrane lipid increased and the antioxidant enzyme activity increased in the treatment group. The oxidative stress injury of soybean leaves was caused by the agent treatment. The effect of spraying triazophos on oxidative stress was significantly lower than that of spraying chlorantraniliprole and compound; the incidence of soybean hyperplasia in intercropping model was much lower than that of net cropping. Under the two models, Longxiang control effect than chloramphenicol and two kinds of pharmaceutical compound effect is better. Triazophos is preferred as a control agent for Glycyrrhiza uralensis.
