The treatment of little-leaf of deciduous fruit trees

Abstract

Following the identification of little-leaf of deciduous fruit trees in the Stanthorpe district as a disorder due to zinc deficiency, experiments were conducted to ascertain the best methods for the application of zinc as a corrective of the disease. A winter spray consisting of a 5 per cent. or a 2.5 per cent. solution of zinc sulphate in water gave satisfactory response within a few months; little control was obtained with a 1 percent solution.
