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
What Moths Prefer- Moths prefer laying their eggs in corn before it tassels. After the crop is in tassel, it will prefer neighbouring fields that are less advanced in crop stage OR they move to dry beans and other host crops (like snap beans, sweet corn etc). Pick the tallest and healthiest look... Continue reading
Lots more WBC moths have been captured in Ontario in the last couple of weeks. We have been having some technical difficulties with our online trapping system and some participants are still not entering their trap data or site information. But from the data that we have been able to collect, I... Continue reading
With this kind of heat AND wheat harvest just around the corner, we should keep an eye out for spidermite activity in both seed corn and soybeans.
I put together a pretty detailed article last year in the CropPest Ontario Newsletter. Visit it to familiarize yourself with what signs to look for. ... Continue reading
