These next two weeks are critical for western bean cutworm scouting and management in dry beans. Peak moth flight took place at the end of July and pod feeding is typically expected 10 to 21 days after peak flight. Huron County is particularly at risk given the very high moth count for that coun... Continue reading
Based on scouting observations and trap counts so far, it looks like we have finally passed the peak for western bean cutworm moth activity. Egg masses are difficult to find now in corn which tells us that the moths are no longer interested in laying eggs in that crop...unless of course there is a... Continue reading
Jim Barclay at Hensall District Co-operative Inc. reported that an early planted otebo bean field in Tavistock has been found with WBC pod feeding injury and will be sprayed.
This is a reminder to growers with early planted dry beans to get out and scout either neighbouring pre-tassel corn fields f... Continue reading

We have found a few corn fields in the Bothwell and Strathroy area that have had above threshold numbers of WBC eggs. I strongly recommend that late planted corn fields that are not in full tassel yet be scouted this week and next. Given that we are at or close to peak moth flight, that means th... Continue reading
I realize that I am bombarding you guys with WBC blog entries but we are entering a critical time for scouting and WBC management. I don't want to find out that you couldn't find all of the information you needed to effectively monitor and determine if you needed to control this pest.
Here are so... Continue reading
We are nearing or at peak flight for WBC. This is nearly 3 weeks ahead of last year. Much of the corn crop is starting to be less attractive for them. Late planted fields not in tassel yet will still be their target but if those are not available, then they will move on to dry beans and snap b... Continue reading
I have heard of grower who is going to spray his corn next week because there have been a lot of WBC moths flying around. This is not an acceptable practice. Trap counts do not necessarily reflect what is going on in the field. It simply tells us when to expect peak egg laying. Scouting is t... Continue reading
I was starting to doubt my abilities to properly scout for WBC eggs, given my height. I walked a lot of fields last year with zero success. I was really good at finding larvae in the fall though so clearly there were eggs to be found earlier that year. You start to feel somewhat of a hypocrit... Continue reading
