Corn rootworm adults emerged a few weeks earlier than usually and are quite abundant this year. This is particularly concerning when the adult populations are high in corn on corn fields planted with a rootworm Bt hybrid. This could be an indication that rootworm populations have developed resistance to the rootworm Bt traits involved. To […]
Harvested wheat fields offer the perfect opportunity to focus on improving soil health. Planting cover crops and/or applying manure or other organic amendments provides soil microbes with the carbon compounds that help create a more porous soil structure which improves water, air and nutrient cycling. Here are a few common questions that come up every […]
Many reports are coming in about silk clipping in corn. Three main culprits include corn rootworm beetles, Japanese beetles and redheaded flea beetles. Regardless of which one is doing it, it comes down to when and where they are clipping and by how much. Corn silks can grow as much as an inch or more […]

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 […]

Reports have already come in of a few soybean fields that have reached threshold and need to be sprayed this week for spider mites.

With winterkill, winter injury and low first-cut yields in many parts of Ontario as well as higher land costs, there is interest in following winter wheat and other cereals with a forage crop to help supplement inventories. Not only can this approach produce some extra feed, it also provides cover crop benefits. There are a few double-crop forage options […]
Wheat harvest 2020 is right around the corner! The conditions are dry in those fields! Once the rush starts it will be “all hands on deck” But remember the slew of harvest/field fires that occurred in July 2016/17/18 under similar dry conditions. Harvest fires result in a financial, emotional and environmental burden to the farm and risks the lives of farm personal, local fire departments and the public and uses firefighting resources. Make sure you are prepared before harvest begins! […]
