In order to clarify the control effect of 25% thiabendazole / pymetrozine WP on rice brown planthopper and Laodelphax striatellus, a community pharmacy experiment was conducted. The results showed that 25% thiabendazole / pymetrozine WP had good control effects on L. striatellus and Nilaparvata lugens, suggesting that the dosage of WP should be 180-360 g / hm2 at the peak of nymphs.
