Hi Sean, I assume you found my low impact spray schedule?
Basically start Surround when the first shucks start to come off. I would also throw in spinosad with Surround sprays if you see any signs of OFM (tip flagging with worms in them).
Saturn is highly rot-prone so you will need to lay on the Serenade/oil or sulphur throughout the season. I put one of the two in every tank. You are fortunately not in as warm a climate as I am, plus rot takes several years to take hold. But, its good to keep beating it back now, it will give you more rot-free years.
There is no need to spray copper during the season; its hard on leaves and the soil (earthworms) as well and should be used only when really required.
