Near Galesville today I found my first Western Bean Cutworm Egg Mass. The moth counts are very low this year. We put out 5 pheromone traps and have found very few this season. I also found a fair number of Corn Rootworm beetles feeding on the fresh silks today. Please keep a watchful eye on your corn fields during the critical pollination phase. The published threshold is “when silk clipping is occurring on 25% or more of the plants during pollen shed.” Also, if this field will be corn next year, it is best to plan your management strategy to combat this pest now due to the fact that they will be laying eggs now to attack next year’s corn crop. Please let us know if you have questions on any of these issues. Thank you.
