In southern Ontario, winter wheat is advancing faster than usual, with some fields at the early boot stage, while others are still in the first to second node growth stage. The article emphasizes the importance of herbicide applications and the need to consider fungicide applications for disease prevention. The article also alerts farmers to potential sulphur and manganese deficiencies in wheat. Meanwhile, planting progress for spring crops like barley, oats, and wheat, as well as soybeans, has been slow due to wet conditions. Soybean farmers are encouraged to use different herbicide traits and ensure accurate record-keeping to prevent mistaken herbicide applications. Corn planting is mainly in lighter soils, and while planting dates can affect yields, the importance is in planting into fit soils. Winter canola is at various growth stages, with some past the fungicide application window for white mould prevention, and spring canola seeding has begun, with adjustments in hybrids recommended based on the region and weather conditions.

Winter wheat is advanced by 10-14 days in southern Ontario compared to other years, particularly in early planted fields. Fields in Essex are now at the early boot stages. Regions of the province further north and east as well as later planted fields are not as advanced and are at the first to second node (GS31-32) growth stages. As fields continue to advance, herbicide applications should be wrapped up. Many weeds being targeted in fields such as chickweed, fleabane, Shepherd’s Purse and dandelion are already past their targeted window and should be controlled in the fall. If fields are at or approaching flag leaf, dollars should be saved for fungicide applications instead of herbicide applications. Figure 1: Winter wheat at the flag leaf stage. To confirm flag leaf emergence, split the leaf sheath above the highest node. If the developing head is present and no additional leaves are contained inside, then the last leaf emerged was the flag leaf. Figure 2: Sulphur (S) deficiency ...
