柑桔上由于长期、单一地使用有机磷等化学农药,导致红蜘蛛、矢尖蚧等害虫产生抗药性,药效下降。复配农药是延缓抗药性的途径之一。我们于1989—1990年受四川省化工研究所委托,进行了喹硫磷两种复配剂对柑桔红蜘蛛、矢尖蚧的田间药效试验。现将两年结果总结如下。一、材料与方法(一)供试材料供试药剂为30.5%增效喹硫磷乳油、30.5%喹菊酯乳油,对照药剂为25％喹硫磷乳油(均为四川省化工所产品)。试验对象为柑桔红蜘蛛和矢尖蚧。试验地点设在仁寿县钢铁乡。
Citrus due to long-term, single use of organic phosphorus and other chemical pesticides, leading to red spider, Agrimony scale pest insects produce resistance, efficacy decreased. Compounding pesticides is one of the ways to delay drug resistance. We were commissioned by the Sichuan Provincial Institute of Chemical Industry from 1989 to 1990, carried out a two-component test of quetiapine citrus red spider, Agrimony scale field efficacy test. The two-year results are summarized below. Materials and methods (a) The test materials for the test agent is 30.5% synergistic quetiapin EC, 30.5% of Quinuifu EC, the control agent is 25% quetiapine EC (all products of Sichuan Chemical Industry). The test subjects were citrus red spiders and arrowhead scale. The test site is located in Renshou County Iron and Steel Township.
