Unfavorable weather during spring months can delay corn planting or make replanting necessary, if germination and emergence is poor.
When corn planting is delayed, the growth and development of the crop is also delayed. This can make the crop more vulnerable to yield loss from diseases and insects since they can affect the crop at earlier stages of development relative to grain fill.
Diligent scouting is especially important in late-planted corn to watch for potential issues and determine if a treatment is economically justified.
This article provides a brief overview of select insects and diseases that can pose a greater risk to late planted corn.
