Managing cold stress in Canadian crops

"Seeding into cold soil is one of the first stresses a crop can encounter. This initial stress can inhibit seed vigor and germination rate, delay crop growth, and decrease crop yield and quality."

"Cold soil temperatures can increase the vulnerability of seeds to soil pathogens, diseases, and pests. Cold, wet soils following seeding can elevate the risk of disease and root rot."

"Cold and wet conditions at and after seeding can harm developing seedlings, delay germination and emergence, and reduce stand establishment. Poor germination and uneven emergence caused by cold stress can also lead to staging issues for in-season herbicide and fungicide applications."

"Seeding into cold soil can be a strategic decision for several reasons. It allows farmers to take advantage of the full growing season, avoid in-season pests and diseases at their peak, and prevent flowering during the hottest periods of the growing season."

Cold stress significantly affects plant growth and crop productivity, particularly when seeding in cold soil. This initial stress can reduce seed vigor and germination rates, leading to delayed growth and lower yields. Additionally, cold soil increases the risk of diseases and pests, particularly soil-borne diseases like Fusarium and Rhizoctonia. While early planting can extend the growing season and avoid peak pest periods, it also poses risks such as slow germination and seedling diseases. Utilizing Biologicals can help mitigate these risks effectively.
