I bought seeds from eBay. I am currently growing an unknown pepper. I want to know if any given pepper is posionous. How do they get that way?
LOL
Buying seeds from eBay IS poisonous.
Some nightshades can look quite like capsicums and most nightshades can be quite deadly.
Foliar ? Doubtful. If you were to drench the soil with something I say maybe--.Can seeds from a plant sprayed with poison be poisonous? I heard that a plant sprayed with some poisons can be permently toxic.
True Nightshades and other members of the nightshade family can be toxic. However Peppers, eggplants and tomatoes are not, the fruit is not at least.
Potatoes can be toxic if the tubers turn green.
Ironic note, I have nightshade growing in my pepper patch.
