The province experienced weather extremes. Southern Ontario saw warmer conditions that supported corn and soybean growth and helped dry fields still awaiting planting. However, wind and scattered rain complicated weed control efforts. In the Northeast and Northwest Ontario, temperatures neared 0°C, raising concerns about frost damage to emerged soybeans and white beans. Field assessments are ongoing.| Field Crop News
A cooler than average start to the growing season has added some uncertainty to post-plant nitrogen fertilization strategies for Ontario corn producers. Soil supply of nitrogen to the corn crop is likely lower than normal due to reduced N mineralization from both soil organic matter and manure, and the Maximum Economic Rate of Nitrogen (MERN) for a given field may be somewhat higher than an average year.| Field Crop News
It’s been a tough spring across much of Ontario and growers continue to face variable weather conditions, creating both opportunities and challenges across regions. Frequent rain events have delayed planting in parts of eastern Ontario, particularly on heavier clays from Belleville to Kingston and Essex which had up to 3” of rain last week halting soybean planting. Unfavourable weather has continued to challenge spray operations across much of the province. High winds have reduced the num...| Field Crop News
Have you been seeing increased corn rootworm pressure in your continuous corn fields over the last few years? Monitoring with sticky traps can help you determine if you have a Bt resistant corn rootworm problem and it helps us keep track of where these problem fields are. Thanks to GFO and ABSTC, we still have some free corn rootworm sticky traps to give away this year to any interested trap participants, new or experienced. Fields with a history of corn on corn and repeated CRW Bt hybrid use...| Field Crop News
