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

Unfavourable weather has continued to challenge spray operations across much of the province. High winds have reduced the num...| Field Crop News
Cooler than normal weather continued, with several overnight lows below 10°C. In the southwest, crop heat units (CHUs) are below normal and about 200 below last year on this date. Planting is progressing as soils become fit; however, crop emergence has been slow. | Field Crop News
Field work progressed quickly across the province in the past week, with sunny skies and warm temperatures peaking on Friday, May 16th before scattered showers and below seasonal temperatures began on the Victoria Day long weekend.
