Abstract
Anthracnose stain on Clementine tangerine and grapefruit, caused byColletotrichum gloeosporioides, is described. Among the fungicides bioassayed against this organism Bordeaux mixture was the most effective copper compound; potent organic compounds were captafol, captan, chlorothalonil, maneb and mancozeb. Bioassay evaluation of fruit treated in the grove revealed that the protection and lasting effect of captafol and Bordeaux mixture were superior to those of chlorothalonil and maneb. Effective field control was achieved even with one prophylactic treatment in July with copper-containing fungicides.
