The potato industry is well aware of the potential effects potato virus Y (PVY) can have on a potato crop. But, what benefits are there in testing for PVY during the potato season?

Why is testing for PVY during the potato season important?

  • Detect the presence or absence of PVY
  • Provide visual evidence of the PVY situation within a crop
  • Monitor or determine the success of disease management procedures

As we mentioned in our article, Are you ready to combat Potato virus Y?, getting a definitive confirmation of the presence of Potato Virus Y is important. Relying on visual detection or hoping that your disease management techniques are ‘just going to work’ isn’t enough, you need to have evidence that your crop is disease free, or not as the is case sometimes.

Agronomists, advisers and inspectors are of course experts and can probably determine many diseases by sight. But, some of their clients may not have the same skill or would like evidence of any disease presence or absence. So, being able to provide visual evidence by way of test results, in the field preferably provides definitive confirmation to clients of the disease-status of their crop. For agronomists this ability to provide visual evidence could aid repeat business?

Another payoff of using a PVY test is that you may be able monitor the success of disease management techniques. If you’re testing a potato crop regularly throughout the season in tandem with employing disease management protocols, then the success or failure of any techniques could be proved or disproved by testing for PVY.  Of course, this methodology isn’t going to work if yield is low due to unmanageable growing or weather conditions because disease management techniques probably won’t have an impact anyway.
