Erin Hodgson will briefly review how to sample insects in field crops, using IPM and the importance of treatment thresholds. She will also talk about the short-term forecast for insect activity in the north-central region.
Dr. Anita Dille will discuss links between “critical period of weed control” and “economic weed thresholds” for making POST weed control decisions. Now that the crops have been planted and growing, weed scouting is done to determine if in-crop weed control is needed. Timing of weed scouting can be based on the ecological principles determined by the critical period of weed control for a given crop. Based on what is found during that scouting event, an economic assessment based on weed thresholds can be used to justify the next weed control practice implemented.
