灭幼脲Ⅲ号是一种无公害的生物杀虫剂。笔者采用不同浓度的灭幼脲Ⅲ号，对油松毛虫进行了防治试验，并与氧化乐果等化学农药进行对比，结果显示，灭幼脲Ⅲ号与对比化学农药有相同的防治效果，其常量喷雾最佳浓度为１００倍液，可有效杀死油松毛虫，而对其天敌伤害极小。
Chlorbenzuron III is a pollution-free bio-insecticide. The author used diflubenzuron III in different concentrations to control and control the pine caterpillar, and compared with the chemical pesticides such as omethoate. The results showed that the diflubenzuron III had the same control effect as the comparative chemical pesticide. Constant spray the best concentration of 100 times the liquid can effectively kill the oil pine caterpillar, while its natural enemy minimal damage.
