Blackleg and Verticillium stripe Test

Blackleg and Verticillium stripe:

PSI will assess submitted samples for both Blackleg and Verticillium stripe.

Verticillium stripe is determined by visual examination of spore colonies generated from symptomatic stems and confirmatory PCR upon request.

PSI’s Blackleg test is in two parts:

1. We confirm visually that the sample has Blackleg. If Blackleg is identified, we use a DNA based assay to determine the population of races present in the field where the sample was taken.
2. If the sample is not Blackleg, we will refund 50% of the testing fee as the race test cannot be done. Follow the sampling protocol for best results.
