You want to use something that says it's safe for fruiting plants. That means it's safe to eat.

I use Garden Safe's Fungicide 3 but I think it's just neem oil and plant soap (can't remember what the soap is actually called). I spray every 7 days, making sure to get the bottoms of the leaves really well. I've not had any bugs whatsoever so far. I also bug bombed the rooms before starting to grow in them.
