co-authored by: Meghan Moran Western bean cutworm can significantly reduce the quality and yield of your dry bean crop. Below are best practices for minimizing this insect’s impact to your bottom line. The simple answer Spraying insecticide for western bean cutworm (WBC) control in Ontario dry bean fields is warranted only if ALL of the […]
Dry beans are either approaching flowering or have already started flowering across Ontario. White mold is an important disease of dry beans in Ontario and in-crop management of white mold occurs during flowering. White mold spores can land on stems, leaves or pods but deteriorating flower petals are very susceptible to infection. Spores colonize flower […]
Background Although named for its affliction on soybean plants, soybean cyst nematode (SCN) can cause comparable damage to dry edible bean crops, and can adversely affect yields and economic benefit, as well as the future use of Ontario’s current dry bean-producing land. Poor yields associated with SCN infestation can be exacerbated by other environmental factors […]
Breakfast Sponsor: Thanks from the group to “Richard Anderson – BASF Canada“ Quote of the week – If you need anything other than glyphosate up front – you haven’t been doing a good job.” Roger Bourassa And a couple more: “Resistant Weeds Cost More Money” and “Not hard finding a tillage resistant weed” Synopsis: There […]
Trap counts are still quite high this week in Ontario which indicates that peak flight hasn’t plateaued yet. So there is likely still lots of egg laying happening. Moths will prefer to lay eggs in later planted corn that is still in pre to early tassel stages or will find dry bean fields nearby. Just […]
The first suspect cases this season of anthracnose have been reported in white beans. This is the time of year when we typically first begin to see symptoms and is a good reminder for the need to scout your fields through to leaf drop. Anthracnose is a potentially devastating seed-borne disease that can affect all […]
Just wrote an article and completed the map of the distribution of western bean cutworm in the Great Lakes Region. Check it out in the latest CropPest Newsletter at: http://www.omafra.gov.on.ca/english/crops/field/news/croppest/2009/18cpo09a3.htm . […]

Sorry…It’s been a few weeks since my last blog but I finally went on holidays. I’m back and want to give you an update. While away, more reports were coming in of western bean cutworm damage being found in Ontario. Others are asking how to scout for the damage this fall so that they can determine if […]
We visited the Newbury WBC site last week and it was concerning to see so many plants infested with WBC larvae. There were no external entry holes from the outside of the ear which could fool those who think the ears are clean. Pay extra attention to those ears that are slightly opened at the ear tip (husk […]
My summer students are going to be frustrated when they find this out, especially with all of the scouting they have done looking for WBC egg masses and larvae and finding nothing to show for it. But today Adam Pfeffer of Monsanto brought in the first WBC larvae found here in Ontario. The larvae was from […]
Some counties in Michigan have been given the recommendation to spray their dry beans due to the high moth counts and observations of pod feeding at some locations. Montcalm County (central Michigan) in particular is at the highest risk with some trap sites capturing over 400-500 moths in the last few weeks. Isabella, Gratiot and Mecosta counties are also considered […]
