So I grabbed the wrong sprayer last night that I had sprayed some copper with a couple weeks ago. Put in my TKO and sprayed my pumpkins. Today I go out to check them out in the afternoon and they look nothing like what I had left them the nigh before. Night before they were healthy and green today they what looks like burnt holes in the leaves. pretty much just makes me sick. Question is to you all will my plants recover from this? Also, copper was used awhile ago and I have sprayed insecticides twice with this same sprayer why would copper still be in sprayer? THanks to anyone who responds and always pay close attention when grabbing your sprayers

I know from working with aquariums that if copper is used to kill parasites on the fish in a tank you can never get the copper out. The tank is pretty much ruined as far as remaining toxic to invertabrates and other copper sensitive organisms. If a material is at all porous it's probably going to leach out for a while.

Most likely was not the copper. Most likely it was from water droplets magnifying the sun creating the burn holes, or to low of a dilution rate for the TKO
