Winter 2021/2022 Conditions Fall of 2021 was very open, and many hay fields grew significantly more than usual. Stands that were predominantly grass created a higher risk for smothering alfalfa where there was too much top growth. Ideally grasses should be mowed to 15 cm (6 in.) to reduce smothering risk. Alfalfa will not smother, […]
Simple Summary there is limited guidance for safe fertilizer rates for strip till – unlike 2”x2” planter banding, there are many different fertilizer placement options in strip till there is likely some tradeoff with fertilizer placement in strip till – placement closer to the seed likely improves starter fertilizer effect and fertilizer efficiency, but likely […]
Crop scouts and agronomists that walk multiple fields in a day should consider biosecurity and preventing the movement of soil, and soil borne pests, between fields. Risk of disease movement from one farm to the next is proportional to the amount of soil moved. While other aspects of farming represent a greater risk of soil […]
Co-authored with Albert Tenuta, Field Crop Pathologist, OMAFRA. OMAFRA field crop specialists in collaboration with Grain Farmers of Ontario (GFO) and members of the Ontario Agri-Business Association (OABA) have completed the annual Ontario corn ear mould and DON mycotoxin survey. Corn ear moulds such as Gibberella and their corresponding mycotoxins occur every year in Ontario. […]
Publication 30: Guide to Forage Production is a comprehensive guide to forage agronomy. It has information on establishment, fertility, weed management and weather stress for many species grown as forage in Ontario. It also covers harvest and storage of forage crops and understanding a laboratory forage analysis. To download a free PDF version or order a […]

Bt-resistant corn rootworm is a serious pest of continuous corn and is a major threat to the silage corn supply. Work with your agronomist and nutritionist […]
When does a killing frost no longer damage soybean seed? Late planted fields or double cropped soybeans may still be green in late September or October. A killing frost will not significantly harm seed quality once the field is at the R7 (beginning maturity) growth stage. R7 is reached when 50% or more of the […]
Cereal rye is a versatile cover crop that can be seeded late into the fall in Ontario. Not to be confused with annual ryegrass – a grass that can be challenging to control – it is a winter cereal that overwinters reliably and grows rapidly in the spring. Delayed termination of rye by herbicide prior […]
Growing cover crop-based organic no-till soybeans requires a different system approach than for standard organic production. Three years of extensive research trials in Ontario have guided the development of four key best practices for growing no-till organic soybeans following a cereal rye cover crop. This tip sheet is designed to provide practical advice for Ontario […]
Tar Spot and Fungicide Application Timings! Although tar spot was detected in Ontario in the first week of July the past two years, 2022 is much different than 2021 and shows the importance of environmental conditions for disease development. Remember, this holds true for any disease! The big difference was the dry conditions early and […]

Traps south of London and in Essex County have had very high captures of fall armyworm. Winter canola, winter cereals, forages and cover crops should be monitored for larvae – not just limited to the region of these traps. Some fields of newly-seeded winter canola had extensive feeding damage in 2021 and had to be […]
Managing cover crops ahead of the 2023 corn crop If you’re like many Ontario farmers, you are not only watching as your crops head toward the finish line, but also keeping an eye on the progress of the cover crops you seeded after cereal harvest. With recent rainfall in many parts of the province, cover […]
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. Bt-resistant Corn Rootworm Corn rootworm is a serious pest of continuous corn. Root feeding reduces yield and increases the risk of lodging and “goose-necking” which can […]
Simple Summary – Changes in fertilizer:corn price ratios (not fertilizer prices alone) change optimum P and K rates. Corn prices increasing with fertilizer prices can limit price ratio changes. – Significant price ratio changes are required to appreciably change optimum P and K rates. For instance, changing fertilizer:corn price ratio ($/lb-P:$/lb-corn) in a recent Ontario […]
