Winter wheat harvest has now wrapped up across much of the province. While yields and the overall season are still fresh in mind, it is a good time to reflect and assess what worked well and where improvements or changes can be made for next year’s crop. Post winter wheat harvest is also an excellent […]
There are a few pests to keep an eye on over the next few weeks. Western Bean Cutworm We likely reached peak moth flight either last week for most of the southern counties or this week for the rest of the province, except Northern Ontario, based on the Degree Day Prediction Model and trap counts […]

Corn Diseases, Fungicide Timing, Fungicide Resistance and Nematode Surveys! Corn diseases such as tar spot, northern corn leaf blight, common rust, gray leaf spot are easy to spot this year especially in areas which have had considerable rain events. The good news is the incidence and severity has still been low as many corn fields […]
Corn Pests to Watch for Over the Next Month Tracey Baute, Entomologist – Field Crops, OMAFA Corn Rootworm Like many other pests, corn rootworm (CRW) is ahead of schedule this year. Adult beetles will be emerging this week or next. Anyone considering trapping for adults as part of the Corn Rootworm Trap Network should be […]
Key Points: What Causes Fires? The process of forage heating up and then burning is typically called spontaneous combustion. Spontaneous combustion for hay usually occurs within the first two months of storage. Unusual growing conditions, such as an early harvest window or immature crop, can complicate the drying process and increase the risk of fire. […]

It was edited June 27, 2023 by Christine O’Reilly to reflect current insecticide options to control potato leafhopper and the cessation of third-party alfalfa variety trials in Ontario. Potato leafhopper (PLH) is the most damaging alfalfa insect pest in Ontario in most years. While the […]
Co-authored with Albert Tenuta, Pathologist, Field Crops and Peter Johnson, Agronomist, RealAgriculture Fusarium Head Blight Management Managing Fusarium head blight (FHB), also known as scab, in wheat is crucial to prevent yield loss, reduce mycotoxin contamination and maximize grain quality. Identification Fusarium Head Blight (FHB) symptoms are noticeable soon after flowering. Diseased spikelets (glumes and […]
Winter canola harvest will be happening soon in the southern counties of Ontario. Some producers and the researchers at AAFC Harrow have already applied a pre-harvest herbicide last week. Here are some resources on staging the crop for harvest. Resources from Canola Council of Canada and Kansas State U have been used to develop this […]
Seedling waterhemp at the 2 to10 leaf stage in 6 leaf corn. Control must be prioritized since herbicide effectiveness will be reduced as this weed gets bigger. […]
Summary: Background: Throughout the growing season, microbes within the soil break down organic nitrogen contained in soil organic matter and crop residues and release it as plant-available ammonium. This process is known as nitrogen mineralization. Nitrogen mineralization is favoured by warm soil temperatures with adequate soil moisture and aeration. Excess moisture can slow mineralization or […]
Areas across the province are seeing variability in corn emergence and growth due to frequent rainfalls. […]
