Add stink bugs to the long list of pests showing up to represent in 2021. There have been several reports of brown stink bug being found in IP soys and dry beans. Stink bugs feed by piercing the pods and sucking on the seeds developing inside. They inject digestive enzymes into seeds, causing the seed to dimple or shrivel. Indirect…
Tracey Baute July 9, 2021 252 Comments Off on Monitor and Report Spider Mite Resistance in Ontario Soybean and Dry Bean CropsWritten by: Tracey Baute, Field Crop Entomologist, OMAFRA, Dr. Vojislava Grbic, Associate Professor, Western University and Dr. Ian Scott, Research Scientist, AAFC-London With the exception of the significant rain events in the last week, this year’s hot, dry conditions and early wheat harvest could be priming us for another bad spider mite season in soybeans and dry beans. Over the…
This article is written by Chris Gillard, University of Guelph – Ridgetown Anthracnose can cause severe yield and seed quality issues in dry beans. Anthracnose is managed in part with genetic resistance, clean seed and chemical seed treatments. Locally grown seed increases the risk of a disease outbreak, and growers are encouraged to use fungicides to manage this risk….
Alfalfa weevil and potato leafhopper (PLH) are being reported as extremely high in many fields. Hot dry conditions have made it more favourable for these pests than their natural enemies (especially entomopathogenic fungi). Scout fields to determine if cutting is possible or if an insecticide application is necessary if thresholds are reached. Consider fields at threshold if both pests are…
Here is the latest update on where the trap catches are for western bean cutworm in the region based on trap site data entered into the Great Lakes and Maritimes Pest Monitoring Network. Peak flight for Ontario and most other states and provinces on the network (except Michigan) occurred during Week 11 (Aug 3-9) (see Fig. 1). Trap catches are…
Before I talked about the WBC trap data, I want to thank everyone who set up a trap this year and are entering their data into the network. Despite COVID-19, there are more than 1000 WBC traps in the system! That is a record and helps us figure out what the flight patterns are. Now for the trap results. We…
Hannah Ross July 15, 2020 987 Comments Off on SCN Survey of Dry Bean Fields in Perth and Oxford CountiesBackground 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 such as soil type, other…
Reports have already come in of a few soybean fields that have reached threshold and need to be sprayed this week for spider mites. This hot, dry weather at the start of wheat harvest is the perfect scenario for significant spider mite infestations to move into soybeans, dry beans and possibly even the corn crop. Spider mites are currently on…
(This article updated on March 5, 2019 with yield data from Agricorp. See table at end of article) Planting and Growing Conditions Acreage of dry beans in 2019 increased approximately 20% over 2018 acreage, with notable growth in acres of white and adzuki beans. Challenging planting conditions for corn and soybeans were likely a factor in the increased acres of…
Meghan Moran October 6, 2019 2240 Comments Off on Made-In-Ontario Yield Monitor Now Available for Dry Bean CombinesIn 2015 an Oxford County farm family, the Vollmershausen’s, were looking around for a yield monitor for their Pickett combine. The Vollmershausen’s grow kidney and cranberry beans which are harvested by pulling and windrowing, then picked up and threshed by a Pickett combine. Large seeded dry beans are somewhat delicate and must be handled gently so that the final product…
There is a long way to go yet before we reach crop maturity and a few insects are thriving right now in late planted soybeans and dry beans. Bean leaf beetles are a risk for both soybeans and dry beans. Reports are starting to come in of some activity at various locations. This is the first generation of adults; what…
Usually by this time in July, I am writing about how we are approaching peak flight for WBC in at least the southwestern counties. But with the delay in growing degree days this year, we have just caught the first WBC moth in Ontario this week, a month later than usual start catching them. Despite the late WBC activity, we…
Tracey Baute July 11, 2019 2295 Comments Off on Pest Watch – Potato Leafhoppers, Thrips and Spider MitesWhat a year! Goes from too wet to too dry. With young crops and little canopy yet, a few pests could become a problem quickly. Especially if hot dry conditions continue to stress the crop further. Scout fields frequently for these three pests; Potato leafhoppers, thrips and spider mites. Potato leafhoppers (PLH) are in high numbers in many counties. Both…
Ontario’s dry edible bean producers are top notch farmers. They invest a great deal of time and money in managing this high risk, high reward crop. To keep the scales tipped towards ‘high reward’, dry bean producers need to know the soybean cyst nematode (SCN) status of their fields. SCN is now present in 22 counties (Figure 1), including the…
OMAFRA Field Crop Team June 13, 2019 2321 Comments Off on Ontario Field Crop Report – Week of June 10th, 2019Corn Significant planting progress was made the end of last week and through the weekend as sunshine and warm temperatures dominated for a string of days. Despite the calendar date and reduced yield potential of later planting, many continued to plant corn noting the competitiveness of returns relative to soybeans. Many areas are reporting corn planting reaching 90-95% of intended…
