Abstract

Samples of potato foliage infected withPhytophthora infestans were collected from the main potato growing areas in Ireland over a three-year period starting in 1981 when metalaxyl-based fungicides were no longer commercially available. Using the floating disc method, 75% of the isolates tested were found to be resistant to metalaxyl in 1981, 21% in 1982 and only 6% in 1983. The reliability of the test method and the sampling procedure to detect low levels of resistance is discussed.
