| Abstract: | Focus on the frequent occurrence of black scurf disease, root-knot nematode and underground pests in main production area of sweet potato in Guanzhong area of Shaanxi in recent years, a field control experiment was conducted by nine low-toxicity and high-efficiency insecticides in the experiment base of Baoji Academy of Agricultural Sciences.The results showed that control effect of azoxystrobin(480g/L) on black scurf disease of sweet potato was 52.93% . The control effect of fluopyram(41.7%) on sweet potato root-knot nematode was 78.79%. The control effect of chlorantranili-prole(200g/L) on white grubs and golden needle beetles was better than phoxim(40%) and bibenthianthiam(1%), and the average commercial rate was 10.62% higher than that the control. |
