Irrigation Water Testing

Irrigation Water Testing for the Water-borne Pathogens Pythium, Phytophthora, and Rhizoctonia

If symptomatic plants are observed, it is best to send a plant sample for analysis, not water: see the Vegetable and Floriculture Diagnostics page for instructions.

Please do not send samples from municipal water sources. 

Water samples: Collect 300-500 ml of water source in a clean water or soda bottle. Cap tightly and refrigerate if not shipping immediately. Use next day delivery. Please do not mail samples on Friday or Saturday. Please fill out the submission form as thoroughly as possible, indicating the presence or absence of symptoms in crop(s).

Diagnostic Fees (payable to University of Massachusetts):

  • Water testing- $50 per sample

Payment Options

By check: Enclose your payment with the sample. Make checks payable to the University of Massachusetts
