Is it worth spraying fungicide on corn at or just after tassel?

We’ve got good moisture & decent fertility for once. Now I’m wondering what else I could possibly do on my end to help hold onto or increase yield? I’m new to using fungicides period, blank slate here.

Typically first brown silk is the best timing if you are going to hit it once.

Thanks! I decided to split a field 50/50 as a trial. If it pays back, I'll try it on some more acres next year as well.

My question is why do you say descent fertility for once? That should be an operator controlled variable..

I recommend to never use a generic fungicide. The generics use a less quality fungicide and won't work as well. Last year we used Trivapr...
