We just had heavy rains followed by unseasonably cool temps, which is a perfect recipe for fungal disease, so I went out and applied Serenade this evening. I added some Coco-Wet. It was my first time using the product, and it really did make a huge difference in how the spray coated and stuck on the leaves. But I just realized after doing some research that I may have applied too much. The amount listed to use is 1/2 tsp/gallon. Since I was mixing the product in a liter spray bottle (I don't have that many tomato plants, and they're not very large), I just poured in a small "glop". However, I keep reading online that I should have just used a "drop". What ended up going in the bottle was probably less than a 1/4 tsp, but possibly not by much--definitely more than a "drop". Did I make a huge mistake? Or is this product gentle enough that I'll probably be OK? Will I wake up to dying plants?
