Plant & Insect Diagnostic Services

Arapahoe County Extension’s professional horticulture staff and advanced Colorado Master Gardener^SM volunteers provide sample analysis for a small fee to help homeowners, commercial growers, crop consultants, and golf course crews. Our sample analysis can help you to:

• Identify causes of plant, turf, tree and shrub problems
• Diagnose diseases or pest problems
• Find safe and effective control measures
• Receive information on pesticide alternatives or non-chemical controls

How it Works:
Please contact us at 303-730-1920 for a description of how to collect and deliver the plant or insect sample. Samples may be dropped off anytime from 8 am until 4:30 pm, Monday through Friday. Turf samples not accepted October – April. Horticulture staff will complete the analysis, confirm results and ensure that you are contacted with up-to-date research-based information on each sample.
