Canada: Fall 2024 winter wheat update

Published 2024년 11월 6일

Tridge summary

Ontario growers are experiencing nearly ideal conditions for seeding winter wheat, potentially leading to a record acreage, with some seeding as late as October. However, persistent summer conditions have caused yellowing in fields, prompting concerns about nutrient and fungicide applications. The yellowing could be due to reduced root growth and nutrient uptake caused by warmer temperatures and dry periods, or specific nutrient deficiencies. Despite some leaf rust finding in winter wheat, it is not significantly concerning due to anticipated cooler temperatures and the fungus's inability to overwinter in northern areas like Ontario. No economic benefit has been shown from fall applied fungicides or nitrogen, and it is advised to avoid such applications. Growers are urged to carefully monitor fields for any issues and only make necessary applications. The majority of winter wheat is in good condition, with no necessary additional applications expected this fall.

Growers across Ontario have been able to seed winter wheat this fall into almost perfect conditions, and there may be a record acreage seeded. A significant portion of winter wheat acres were seeded in September but with persistent summer like conditions, growers continued seeding well into late October. Early planted fields are well tillered with 3-4 tillers/plant and late October planted fields are at the 1 to 2 leaf stage. Winter triticale and winter barley fields are also tillering significantly with winter triticale fields planted in early September having 7+ tillers. While almost every acre was seeded into ideal conditions, there are reports of yellowing fields across Ontario and Quebec (Figure 1). This has stimulated questions regarding fall fungicide and nutrient applications to correct this yellowing. With above normal temperatures, winter wheat growth above ground is rapid; however, under these warmer temperatures, wheat root growth is slower. Photosynthate partitioned ...
