The corn trumpet mouth will insecticides and bactericides mixed, one-time pest control, to reduce the late growth of maize pests base and reduce the extent of disease damage for the purpose. Demonstration results showed that the average pest control effect in the core demonstration area was 63.58%, the average disease control effect was 63.47%, 14.24% more than that in the control area, and the mu efficiency gain was 122.9 yuan. The average pest control effect in the airplane control area was 66.23% The effect is 63.85%. 11.31% more yield than the control area, 94.5 yuan of mu efficiency.
