This article was written by Horst Bohner, OMAFRA Soybean Specialist, and Albert Tenuta, OMAFRA FIeld Crop Pathologist Phytophthora root rot (PRR) is one of the most destructive soybean diseases in Ontario. PRR thrives in wet soils, so the incidence of this disease is more prevalent in fields that received excess rainfall in 2021. Clay soils, […]
Scout vulnerable crops for feeding and larvae including winter canola, winter cereals, forages and cover crops. Especially in the southwestern counties but not limited to this area. Currently, there seems to be a pocket in the Blenheim area that requires attention. Meghan Moran has found three winter canola fields near Blenheim this week that have […]
Ontario Hay Listings is a free classifieds service provided by the Ontario Forage Council. Producers looking to buy or sell hay or straw are encouraged to post an ad. In 2020 there were several reports of corn rootworm injury to hybrids with below-ground protection from Bt traits. This suggests that Bt-resistant corn rootworm populations exist […]
Pre-harvest sprouting Pre-harvest sprouting is the initiation of grain germination prior to harvest (Figure 1). Why is that a bad thing? When sprouting occurs, alpha-amylase is produced which converts starch into sugars that fuel seedling growth. High alpha-amylase in the grain can have varying effects on the processing of wheat products. In high moisture, batter-based […]
This article was written by Alex Barrie, OMAFRA Soil Management Engineer, and Ian McDonald, OMAFRA Crop Innovations Specialist As discussed in the previous article (available here), as long as we are putting heavy implements on farm fields, soil compaction is a significant possibility. Lots of factors impact the severity of threat, like load, tire configurations […]
I spoke with an agronomist about a grower who started variable rating nitrogen (N) in corn. Logically, given that high yielding corn takes up more N than low yielding corn, the grower was going to variable rate N by yield across the field – more in high yielding areas, less in low yielding areas. The […]
For many Ontario farmers, the 2021 season has been a weather roller coaster. Throughout much of the province, the season started out extremely dry, with some regions receiving less than 20% of normal precipitation for the month of May (Figure 1). Late June brought relief for many parts of Southern Ontario, with regular rainfall […]
Assessing Soybean Performance Soybean harvest has begun, and yields have generally been good. Many growers are reporting above average yields. But there are fields that underperformed. For those fields that yielded less than expected, it’s important to assess why in order to make good management decisions for the future. Sometimes we blame the weather or […]
There has been considerable discussion around tar spot disease in corn this season and of course many questions as well. Let’s go over some of these questions! Where did Tar Spot common from? In 2015, Tar Spot was confirmed in the Midwest US (Indiana/Illinois) where it was believed to have been blown in from Mexico […]
Managing phosphorus for improved water quality: best practices depend on where you farm Thanks to drier-than-normal spring seasons the past two years, harmful algae blooms in 2020 and 2021 in the western basin of Lake Erie have not been as severe as in preceding years. Phosphorus (P) loading to the lake, however, remains an important […]
What Will Be the Corn Nitrogen Story for 2021? While the 2021 growing season started dry, regular and often heavy rains started for many areas from Southern to Eastern Ontario from late June through July. Some received well above normal rainfall in July. Naturally, conversations began revolving around “are we losing nitrogen (N)” or “will […]
Ontario Hay Listings is a free classifieds service provided by the Ontario Forage Council. Producers looking to buy or sell hay or straw are encouraged to post an ad. AAFC’s Agroclimate Impact Reporter is interested in how weather impacts farms throughout the growing season (i.e. what’s really happening on the ground). This ag-sector citizen science […]
Several reports of fields with fall armyworm (FAW) larvae have been coming in over the last few days. Growers or scouts drive by a field and pull over, shocked to see only stems left of plants with larvae happily feeding. So far most of the damage has been found in oats, rye cover crop, mixed […]
It is safe to say that western bean cutworm (WBC) is a pest that we can rely on entering corn and dry beans every year in Ontario. Though a frustrating pest to scout for, using traps to monitor moth flight has helped us better predict when to expect peak moth flight occurs, which is shortly […]
Tar spot in corn was first identified last year in Ontario on September 21, 2020 and confirmed to overwinter in Ontario on July 2, 2021 in West Elgin. Since then, tar spot has been also detected in Essex, Chatham-Kent, Lambton, Middlesex and Norfolk counties as of July 18, 2021 (Figure 1). This was anticipated since […]
