Research Project: Determining Optimal Sampling Strategy of Woody Plants for Virus Detection (part 2)

Location: Horticultural Crops Research

Project Number: 2072-21220-002-43-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2015
End Date: Jul 31, 2019

Determine the optimal time of year for sampling woody plants for virus detection, and to determine minimal number of leaves per plant to sample to have 95% confidence in detecting a virus in an infected plant.

Various woody plants will be sampled at multiple times during the growing season as well as during the dormant season for virus detection. Detection viruses in several virus families will be carried out on each sample to determine optimal time for detection for a broad range of viruses in woody plants. Additionally, various plant tissues, roots, buds, leaves will be sampled to identify optimal tissues for sampling for multiple virus families. Finally, multiple numbers of samples will be collected per plant at various time of the year, to determine the number of samples needed to be detect a virus with 95% reliability.
