Sending the entire plant for diagnosis is always best. Each situation is different, and we understand that sending an entire plant may not always be an option.
A completed Plant Diagnostic Form is required for all submissions.
Entire Plant
-
Complete a Plant Diagnostic Form with as much detail as possible including site information, pesticide applications, and the symptoms of concern.
-
Send the entire plant in it's container. Wrap the container and roots in a plastic bag and secure with string or a twist tie to keep soil off the foliage of the plant.
-
Pack the plant securely in a box that is large enough to hold the entire plant. Placing newspaper or other packing materials around the plant eliminates movement in the box.
-
Seal the completed Plant Diagnostic Form in a separate plastic bag and place the bag in the shipping box.
-
Seal the box and ship using next day delivery service.
Stems and Leaves
-
Complete a Plant Diagnostic Form with as much detail as possible including site information, pesticide applications, and the symptoms of concern.
-
Send a generous amount of leaves and stems which show a range of symptoms, usually from very symptomatic to near normal leaves.
-
Pack the plant material securely in a box or padded envelope. Wrap plant material in newspaper or other packing material to prevent crushing during shipping.
-
Seal the completed Plant Diagnostic Form in a separate plastic bag and place the bag in the shipping box or envelope.
-
Seal the package and ship using next day delivery service.
