The results showed that the combination of 5% Fritter SC and 90% trichlorfon powder had better control effect on rice white spike caused by the third generation of rice stem borer, and the control effect was better than that of the fipronil alone. The control effect on white spike was 93.94% in the year when the yellow rice borer was born in the year with Fiji special 300ml / hm2 + trichlorfon 1200g / hm2.
