| Abstract: | The test was carried out to screen out ideal pesticides to control the beet armyworrn on cauliflower, and the tested pesticides were 20% chlorantraniliprole, 10% chlorfenapyr, 24% methoxyfenozide and 20% metaflumizone. The results showed that, seven days after applying the pesticides, all the six treatments had the highest control efficiency, with all the control efficiency higher of 85%, while the control efficiency was decreased after ten days of applying the pesticides. Compared to other pesticides, 20% chlorantraniliprole possessed the best control effect, with better quick-acting and longer persistent period, and it could be used with 20% metaflumizone and 10% chlorfenapyr alternately. |
