摘  要:
通过2年4地的田间药效试验,研究了新型硫脲类杀虫杀螨剂丁醚脲防治柑橘红蜘蛛的应用技术。结果表明,50%丁醚脲可湿性粉剂在175~250 mg/kg剂量下对柑橘红蜘蛛的防效与调查时间有关,其1~7 d的防效呈上升趋势,10~15 d防效最佳,20~30 d防效开始下降。50%丁醚脲可湿性粉剂防治柑橘红蜘蛛推荐剂量为200~250 mg/kg,在发生始盛期施药,并因正温度系数的特性,需要在晴天施药。本文还探讨了丁醚脲的应用策略,为该药剂应用的深度开发提供有益参考。

摘  要:
The application technology of diafenthiuron,a novel thiourea insecticide/acaricide,against spider mites on citrus was studied by two-year and four-field trials.The results showed that the control effects of diafenthiuron 50% WP against spider mites on citrus changed along with investigation time.The control effects showed upward tendency in the period of 1-7 d,optimum in the period of 10-15 d and downward in the period of 20-30 d.Recommendation dosage of diafenthiuron 50% WP against spider mites on citrus was 200-250 mg/kg.Spray period must be on a sunny day and in prosperous beginning stage of spider mites.Some application strategies were discussed.They were beneficial to develop application technology of diafenthiuron deeply.
