Western Bean Cutworm Update
Western Bean Cutworm continues to be a concern for pollinating corn in areas with high trap counts. Peak moth flight has occurred in counties in the southwest but counties in Central and Eastern Ontario have not reached peak yet. Moths will now be looking for late-planted corn that is still in the early tasseling stages or will focus on edible beans. Focus scouting efforts in those corn fields that do not have dried silks yet. Edible bean growers need to scout for pod feeding once pods are present. Edible bean fields that are adjacent to corn fields that reached WBC eggmass threshold this year are likely also at risk. It is best to control fields as soon as pod feeding is observed. The larvae are exposed to the insecticide when they make holes in the pods to get to the seed.
For additional information on WBC thresholds as well as optimal scouting and insecticide application timing, see the Field Crop News website.
Information on product choices is available in the OMAFRA Field Crop Protection Guide (ontario.ca/ctaw).
Post Wheat Harvest Manure Application
For livestock producers and those using organic amendments, the post wheat harvest season is an excellent opportunity to apply manure for nutrients and organic matter. Spreading workload, reduced compaction and reduced risk of environmental losses from runoff and erosion, as well as the opportunity to combine the benefits of feeding cover crops with manure, are a
