Conclusions
Scab was greatly reduced in infested Leon fine sand, prairie phase, by treating with sulfur, but the pH reactions established were not suitable for the best growth of potatoes. Consequently, the advantages of controlling the disease by such a treatment may be nullified by loss in yield of potatoes grown in the sulfured soil.
Scab was also reduced but not eliminated from the first crop of potatoes grown in soil which had been treated with both sulfur and limestone between potato crops. This treatment does not appear practicable either, for the disease increased the second year and was almost as severe on potatoes grown in the treated land as in those grown in non-treated land.
