摘　　要：通过田间小区试验,确定新型杀菌剂氯啶菌酯对稻曲病(Ustilaginoidea virens)和稻瘟病(Magna-porthe gresea)的防治效果,以每公顷使用有效成分100～150g对水900L,防治稻曲病在水稻抽穗前5～6d喷雾施药1次,防治稻瘟病在发病初期施药,10d后增施1次,防治效果均可达到90%左右。Ustilaginoidea virens and Magnaporthe gresea are two serious diseases of rice in china. It is found that using fungicide is one of practical methods to prevent and cure these diseases. The results of experiments in the rice fields showed that new fungicide SYP-7017 could effectively prevent and cure those diseases by spraying the mixture of 100～150g fungicide with 900 liter water per hectare 5-6 days before rice heads sprouting. Had the rice been affected, we can also spray the same mixture at the early stage, and apply the chemical again 10 days later. Both treatments will prevent and cure 90% of the rice.
