Spidermites Are Thriving in 2020 – Be Vigilant
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. […]

Forage Options Following Wheat
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 […]
Avoiding, Preparing For and Reacting to Harvest Fires
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! […]
Ridgetown – Simcoe Ag Business Breakfast Meeting – June 30, 2020
Weather update: Most of the area is under hot and dry conditions. Spotty thunderstorms have resulted in variable rain ranging from no rain to 5 inches at Stoney Point (Essex).

Erosion Assessment Goes Geospatial
While managing soil microbes might be the newest frontier to improving soil health, one thing has not changed: you cannot improve soil you no longer have! Minimizing erosion is the first step in a soil health management plan. The old adage says: “you can only manage what you measure”, but actually measuring soil erosion is very complicated, even for experts in this field. There’s no need to measure Cesium isotopes along that slope in your field. What needs to be managed is the risk of erosion. […]
OMAFRA Field Crop Report – June 25, 2020
Wheat Pests are Still a Concern True armyworm (TAW) larvae are in many winter wheat and spring cereal fields across southern Ontario, thankfully not always at threshold. Some fields have populations at threshold (4-5 unparasitized larvae smaller than 2.5 cm per square foot) or above and with minimal feeding damage. Larvae sometimes choose not to […]
Impacts of Climate Change on Current and Future Crop Pests in Ontario
Tracey Baute, Field Crop Entomologist, OMAFRA Climate change will have a direct impact on insect pests. Since insects are cold blooded, they are directly influenced by temperature. Those that feed on plants also rely on the availability of their host crops to survive. Though we have an idea of some of the impacts climate change […]
Exeter and Mt Forest Agribusiness Breakfast Meeting Minutes – June 23, 2020

Corn Crop advisors are getting a lot of questions right now about leaf wrapping and yellow flash on corn leaves. While this may look similar […]
Introducing PLATO, the Phosphorus Loss Assessment Tool for Ontario
Keeping soil covered and minimizing erosion is a key principle of soil health. Maximizing the efficiency of crop nutrient uptake and minimizing losses are the foundation of 4R Nutrient Stewardship. When combined, these principles form the basis of a new online tool from OMAFRA called PLATO (Phosphorus Loss Assessment Tool for Ontario). PLATO is a calculator that you can use to estimate the risk of phosphorus loss on your farm. It’s part of the newly re-vamped AgriSuite and uses your specific soil, crop and nutrient application information to provide a risk rating and options to improve your score. […]
