What is a Sample?
A sample should consist of enough representative material (plant or insect), usually from the same source, so that an accurate diagnosis can be made. Samples from separate sources representative of different problems or pests constitute several samples.

Each specimen submitted must be accompanied by a Specimen Identification Form. Forms may be obtained at your local Extension office, or at any of the five District Research and Extension Centers

Mailing your sample:
Follow instructions on the back of the Specimen ID Form. Your sample should be placed in a crush-proof box or padded envelope. Include your Specimen ID Form and sample fee.
