An “unprecidented” fall armyworm moth flight catch in Kentucky gives us early warning to a potential threat here. The University of Kentucky is reporting the highest catches recorded in the last 15 years. What does that mean for us? If weather fronts or leftovers of a hurricane pass over Kentucky and push towards us, they […]
Since my blog entry last week where I mentioned that we hadn’t found WBC feeding in dry beans yet, my crew as well as reps who have been sending photos in have found WBC pod feeding in dry bean fields at a few locations across the province. To date, sites known to have WBC pod […]
Travelling the country side yesterday, I saw too much spider mite damage going out of control in soybean fields that were easy to spot from my car. Too many fields that still have some time to mature are seeing sure signs of spider mite activity. Some are already too late to control, as the mites […]
I’ve been in a lot of dry bean fields this week, mainly in Huron County. And I will admit that in a few fields, it was tough to sort out what was causing the damage. But so far, there are only one or two sites out of all of the ones I scouted that have […]
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 county this […]
I am still hearing from people who are looking for WBC egg masses on corn leaves. But unless they are scouting very late corn that is not in tassel yet, most of the WBC will already be larvae on the tassel or more likely in the ear. So focus on scouting the ears and tassels […]
I was sent a message today from Deb Campbell of Syngenta Seeds, that they are finding fall armyworm in corn in Grey, Perth, Oxford, Huron and Simcoe counties. Infestations are low and the larvae are small but it is something to keep an eye on. There could be fields with heavier infestations. Also, both Michigan […]
It hasn’t been since 2002 that we have experienced this low of levels of soybean aphids. Cross my fingers and knock on wood but I think we are going to get through the season without a problem. That said, spidermites are starting to pop up in fields, particularly where it is starting to get a […]
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 an extremely […]
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 for egg masses and if […]

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 […]
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 some […]
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 […]
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 […]
