试验比较了在樱桃树生长季节喷施16种杀虫剂防治桑白蚧的效果。认为桑白蚧孵化盛期喷施1～2次40%杀扑磷乳油1500倍液、48%毒死蜱乳油1500倍液、90%灭多威可溶性粉剂3000倍液具有较高防效;其次为20%丁硫克百威乳油1500倍液、5%氯氰菊酯乳油1000倍液、20%三唑磷乳油1000倍液、50%二溴磷乳油1000倍液、20%丙溴磷乳油1000倍液。樱桃成熟期防治桑白蚧,应严格遵照安全间隔期,提前或拖后喷施菊酯类或残效期短的有机磷类农药,如氯氰菊酯、毒死蜱、二溴磷等。
The experiment compared the effect of spraying 16 kinds of insecticides on the control of mulberry white scale in the cherry tree growing season. The results showed that the mulberry white scale had a higher control effect when spraying 1 ~ 2 times 40% Ketofostaphir 1500 times, 48% chlorpyrifos 1500 times and 90% methomyl soluble powder 3000 times 1% carbosulfan 1500 times EC, 5% cypermethrin EC 1000 times, 20% triazophos EC 1000 times, 50% dibromo phosphoric EC 1000 times, 20% profenofos EC 1000 times. Cherry mature period control mulberry white scale, should strictly comply with the safety interval, early or late spraying pyrethrins or residues of short-lived organic phosphorus pesticides, such as cypermethrin, chlorpyrifos, dibromide and so on.
