Managing Phosphorus to Reduce Losses Phosphorus (P) is an essential plant nutrient. Sufficient phosphorus fertility means improved root growth and winter hardiness, accelerated maturity, and improved yields. However, when phosphorus makes its way off of fields through runoff or tile drains, it can negatively impact the health of rivers and lakes. Lake Erie is the […]
With the delay in growing degree day accumulation and crop maturity, many fields are still in the ideal growth stages that put them at risk of some of our later season pests and diseases. Western bean cutworm (WBC) Peak moth flight for western bean cutworm has finally passed for all regions of the province. Central […]

Most fields in the […]
We are still seeing WBC trap counts going up in most counties north and east of Perth. That means that WBC moth flight has not yet peaked in those counties. This is important because this also means that we haven’t reached peak egg laying in those counties and that there are a wack of moths […]
Western Bean Cutworm Update Western Bean Cutworm continues to be a concern for pollinating corn in areas with high trap counts. Peak moth flight has occurred in some of the counties in the southwest but counties east and north of Middlesex and those in Central and Eastern Ontario have not reached peak yet. Moths will […]
For over 30 years, the Ontario Agriculture Weed’s team has competed in the Collegiate Weed Science Competition organized by the North Eastern Weed Science Society.

Cover Crops The underseeded red clover is looking pretty good where the winter wheat has been harvested. As is often the case some fields have variable stands and others have poor or non-existent stands.
