Abstract
Copper Nordox (Cuprous Oxide) and Sicarol (Pyracarbolid) applied by the conventional or the alternating of the conventinal and the Overhead methods of spray application were superior to the Overhead method in coffee leaf rust (Hemileia vastatrix B. and Br.) control. However, in almost all cases, Sicarol appeared less effective than Copper Nordox in the control of the same disease.The effectiveness of the Conventional and the alternating the Conventional and the Overhead methods of spray application in coffee leaf rust control was attributed to the effective distribution of fungicides on both sides of leaves. There was a time saving factor during the spraying when the two methods of spray application were alternated.
