How much copper sulfate per acre was that?
Did it burn any?
I was trying for 10 lbs/acre. I didn't have agitation in the holding tank, so I don't think I actually got quite that much on. The ear leaves tissue tested over 50 ppm copper a couple weeks later. I couldn't see any effects visually or on the yield monitor.
