How to collect a sample

Insects

  • Capture insects and immediately kill by freezing. Leave in freezer overnight. Pack gently with tissues or cotton in a stoppered vial. If desired, include sample of damage.

  • Do not place butterflies, moths, or bees in alcohol, as key diagnostic features will be ruined.

  • Do not bring crushed insects or insects caught on tape or on sticky traps

Plant Diagnosis

  • Select plant material showing symptoms of concern and submit various stages of the problem, especially the early stages.

  • Many problems originate belowground in and around roots-- include roots and soil for more accurate diagnosis!

  • Please do not submit dead, dry, decayed or rotted samples as they provide insufficient material for diagnosis.

Turf

  • Collect samples of turf showing the symptoms of concern that is at least 4 inches by 4 inches square and 3 inches deep. Include roots, thatch, and soil!

Plant ID

  • Plants are classified on floral morphology and identified using various plant parts including flowers, fruits, leaves, buds, and stems. Send as much plant tissue as possible to give a good representation of the whole plant.
