Tissue sampling is occurring. It is important to take correct part of plant as we are in various stages of growth and also mark paperwork with correct stage of growth. Corn is now at upper most mature (3rd yellow collar visible) leaf but at tasseling ear leaf is recommended. Soybeans are upper mature trifoliates. Be sure to submit a softball or double fist size of material. Do not ship in plastic lined containers or envelopes. Order supplies either on line or calling our office.
