Progresses of pesticide reduction techniques and the synergistic effects on the control of rice leaffolders Cnaphalocrocis medinalis
Cnaphalocrocis medinalis is one of the most destructive pests on rice.Chemical control is an effective method to control this pest insect,but excessive use of chemical pesticides will increase the insecticide resistance and pollute the environment and ecology,so the control technology of chemical pesticide reduction and efficiency enhancement is particularly important.In this paper,the occurrence of C.medinalis,its resistance to insecticides and the technology of reducing and increasing the effect of chemical insecticides were reviewed.On the basis of scientific seed selection,scientific water and fertilizer management and accurate forecast,the control of C.medinalis was combined with green control technologies such as ecological regulation,physical and chemical control and biological control,and through the rational selection of high-efficiency pesticides,additives and high-efficiency pesticide application equipment,and enhance the demonstration role of green control demonstration base.As a result,the purpose of reducing the dosage and increasing the efficiency of pesticide would be achieved.
