  • In order to improve the effect on control of Spodoptera frugiperda in maize grassland and delay the development of chemical resistance in Spodoptera frugiperda， single agent of emamectin， compound agent of emamectin and synergizing agent of emamectin were selected for the field experiment. The results showed that under the condition of ensuring the safety of crops， four kinds of chemical treatments were applied (treatment A： 5% metrel salt + synergist emery， treatment B： 5% Metrel salt， treatment C： 30% metrel-indocarb， treatment D： 15% Metrel. The adjusted death ratesat 3 days after treatment reached 84.21% to 87.27%， among which A treatment was the highest， but there was no significant difference among the treatments. After 15 days of application， the growth rates of damaged maize in A， B， C and D treatments were 1.54%， 6.15%， 4.92% and 4.15%， respectively， which were lower than that of 15.5% in CK treatment. The treatment A with the higher mortality and the lower growth rate is with good potential in control of Spodoptera frugiperda.
