Corn:
Corn development is still variable, with fields from vegetative stages to R1 (silk – one or more silks extend outside of husk leaves) appearing on the early planted crop.
Corn fungicide timing (depending on the protection goal and product) is occurring. With recent conditions, Gibberella ear rot could be a concern. Growers are also asked to scout for tar spot. It was found and confirmed in Ontario earlier this month and has now been identified in Essex, Chatham-Kent, Middlesex, Elgin, Waterloo and Haldimand-Norfolk. Tar spot was discovered in the province in 2020 and moved as far east as the Simcoe and Durham regions in 2021.
Soybeans:
Soybeans are anywhere from the V4 (late planted) to R4 stage (full pod- pods are ¾” long at one of the four uppermost nodes on the main stem). Overall, fields are looking variable.
Fungicide timing is occurring or approaching for white mould control. Pockets of aphids are showing up in regions of Ontario.
