Hopefully you won't need to spray anything.
I have been growing Wild Simulated fo seven years now(50,000 plants), and have not seen a big problem with disease in first year plants.
One spring I did lose about 3000 seedlings to a pre emergence \"Damping Off\" disease that killed the seedlings before they emerged through the leaf mulch. This is usually caused by a disease that's already in the soil.
The biggest cause of disease is not having good water drainage in your soil. Soil being too wet. usually from: planting on flat ground instead of on a hillside, too soggy, poor soil quality and planting plants too close to each other.
For first year seedligs it helps to rake off excess mulch before seedlings emerge. You should have only 1 inch of mulch covering. And if the leaves are matted down to the soil, they need to be fluffed up so the little seedlings can find their way through.
Fungicides are most effective in preventing disease before it happens. Least effective after the disease has already established it's self on the plants.
Their are two types of fungicides. Man made chemicals and natural organic fungicides that are made from natural things found in soil, such as Azoxystrobin and Trichoderma.
This year I will be applying natural Trichoderma Plant Helper to all my seedlings before they emerge, to protect them from \"Damping off disease\" and other diseases.
Here are two good pages that lists all the diseases and the appropiate fungicides to use.

Here is the Plant Helper page for Trichoderma:

I have heard that some spray funcides after every rain during the spring time. I have not found that to be necessary.
Hope you find this helpful.
