Abstract
Field experiments were conducted from 1986 to 1992 to determine the effectiveness of spray programmes using phenyl ami de/mancozeb mixtures in controlling late blight of potatoes. These mixtures were used as the first three sprays in a 10-spray programme, with the remaining sprays being of mancozeb. Compared with mancozeb alone, phenylamide/mancozeb mixtures resulted in a significant delay in disease onset in 6 of the 7 years of the experiments while the level of foliage blight at the end of the season was significantly lower in 5 years. Total and marketable yields were significantly higher and tuber blight levels after storage were significantly reduced in 3 of the years. The effect on yield was greatest when disease pressure was highest. Phenylamide-resistant inoculum was present in the trial area in all 7 years of the study.
