What are the control methods for corn borers?
How to control corn borers? Please explain the methods. Corn borers (corn borer) are a major pest of corn. In years with severe infestation, they can reduce corn yields by more than 20%. Their larvae bore into the main stalk and ears, which can break the main stalk of corn, causing reduced yield and quality. In the past, controlling corn borers mostly used methods such as pouring pesticide solution into the whorl, spraying, or applying poisoned soil into the whorl, which was labor-intensive and ineffective, and easily caused crop damage and human and livestock poisoning. Using granule formulations to control corn borers not only has low cost, saves labor, and is effective, but also is unlikely to cause human and livestock poisoning or crop damage. The following points should be mastered:
