Wheat tissue samples are approaching the flag leaf stage. Corn and soybeans tissue will be the entire above ground portion of the plant. 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.
