Abstract

SUMMARY Common scab ( Streptomyces scabies ) on ‘Majestic’ potato tubers was checked by irrigation maintaining the soil at saturation (‘field capacity’) throughout tbe growing season more than it was by irrigating only before the first tubers had grown to 1 / 4 ‐ 1 / 2 in. diameter. The stage of the tubers when irrigation was started or stopped affected the distribution of scab lesions on their surfaces and infections were rare on tissue formed when soil was saturated.
