Corn plants tissue when tasseling and later is ear leaf. Soybeans at V5+ are youngest mature leaves. We need a softball or double fist amount of plant tissue. Do not ship in anything that is plastic lined and be sure to include the plant analysis history information sheet for proper identification and so we can help with any diagnostics that may be needed.
