Qilu.com Lightning News, July 1 - At present, it is an important period for the management of summer corn seedlings, and it is also a critical period to determine the high yield of corn.
There are many kinds of insect pests at the seedling stage of corn, and the damage is serious. There are both underground pests and aboveground pests, resulting in the lack of corn seedlings and broken ridges, which seriously affects the growth of corn. Agricultural experts remind farmers not to ignore the prevention and control of various corn pests while weeding after seedlings.

The prevention and control is also very simple, with emamectin salt, cyhalothrin, plus thiamethoxam or clothianidin, plus lice and urea, so that the eggs can be killed. During field investigations, it was found that there were eggs of bollworm on individual leaves, so the eggs were killed. ”
