Abstract
Abstract ‘Golden Delicious’ apple ( Malus domestica Borkh) foliage is subject to necrotic leaf blotch (NLB) associated with premature leaf drop with up to 50% defoliation at harvest time. In Santa Catarina State, Brazil, incidence of this physiological disorder could be reduced significantly by spraying with ziram, a fungicide containing 19% metallic zinc. An oil paste formulation of ziram was especially effective. The addition of zinc oxide (0.1%) to spray mixture at 2-week intervals further reduced the rate of premature leaf drop. When zinc oxide was added to ziram oil paste fungicide, premature leaf drop was reduced from 41% for the worst treatment down to 4.7%.
