Abstract

Scab or black spot is the most important disease of pears in Western Australia where for many years it has seriously affected both yield and quality of fruit. In seasons favourable to its development, the disease has proved difficult to control with the older copper and sulphur fungicides. Excellent control has been obtained in recent spray experiments with the newer organic fungicides captan and the phenyl mercury compounds. Eradication of the disease in isolated orchards has been achieved by the use of phenyl mercury sprays in the autumn before leaf-fall.
