Disease Diagnosis Services

Plant disease diagnosis = $87 per sample

This is our most frequently requested service. The service includes overall evaluation, including microscopic exam, results from a moist chamber, isolations onto artificial nutrient media, and identification of fungi or bacteria to genus. Viruses are diagnosed using serology or electron microscopy. Measurement of soil pH and total soluble salts will be performed if necessary. Management recommendations are included.
