Growing Medium Sample Collection Guide TUMI Genomics’ Fungal screen diagnostic assay uses a TaqMan qPCR to detect the presence of pathogenic Pythium and Fusarium species in growing medium samples that have been previously plated in petri dishes for 7 days. This product allows for 01 sample of growing medium to be tested. Results take 2 weeks to be delivered. The primer/probe sets target the Pythium and Fusarium genomes. The Pythium species detected in the assay are: P. dissotocum P. myriotylum P. ultimum P. alphanidermatum The Fusarium species detected in the assay are: Fusarium oxysporum Fusarium solani Fusarium proliferatum fusarium brachygibbosum Note: The assay detects the presence of pathogenic Pythium and fusarium. If you would like to identify the species infecting your plant we have Pythium and fusarium speciation tests available. Please contact [email protected] for pricing.
