One of the topics of discussion this winter at the corner table of the local coffee shop most certainly was the upcoming growing season and the expected higher than average insect populations due to the mild temperatures this winter. That topic of discussion paired with high armyworm and black cutworm moth captures from neighboring states should keep early season insect pressure at the forefront of growers’ minds this year. Insects that overwinter as adults such as bean leaf beetle, flea beetle, and stink bug will have the potential to have higher than normal populations early this spring. However, just because insect mortality was lower this winter does not mean there will be a problem this spring because populations may have been lower heading into winter. Nevertheless, lets look at some of the insects to keep an eye out for this spring.
Corn flea beetle that overwintered as adults are the vector for Stewart’s wilt that can cause seedling corn plants to tiller and yellow striping in the leaves.… Continue readingRead More »
