As wheat heads first emerge from the boot, the clock starts ticking — from fully emerged you’ve got about six days to protect the head from the dreaded fusarium head blight. Farmers should target a fungicide application to coincide with heads on 75% of plants at around Day 2 to Day 4. Not sure what we mean? Don’t worry, as Wheat Pete, a.k.a. Peter Johnson, cereal specialist with OMAFRA, will show you exactly what this looks like and why this is the optimal time to spray a fusarium-targeting fungicide.
In this Wheat School episode, Johnson walks us through how to deal with variable fields (that is, all of them), and shows us how to time a fungicide application for Day 2 to Day 4.
