Detection of resistance in Phytophthora infestans to the carboxylic acid amide (CAA) fungicides using digital droplet PCR.

ABSTRACT:

Background

Potato late blight caused by Phytophthora infestans remains the greatest biotic threat to potato production globally. In northern Europe to prevent the disease and associated yield losses fungicides are heavily relied upon, with multiple applications required during the potato growing season. Unfortunately, such intensive fungicide usage has the potential to compromise control efficacy as it puts in place immense selective pressure for the emergence and spread of fungicide resistant strains of P. infestans. In recent years this scenario has been realized, with the emergence of strains resistant to the carboxylic acid amide (CAA) fungicides. As resistance to the CAA fungicides in P. infestans has been confirmed to result from changes in the pathogen's cellulose synthase A
