Abstract

SUMMARY Metalaxyl and fosetyl-AI, which are already registered for the control of Phytophthora root rot of avocados, were tested together with Ethazole, Dowco 444, Chevron 20615 and Previcur N against root rot on young Guatemalan seedlings replanted in naturally infected soil. Metalaxyl and Ethazole gave the best control of the disease. The other chemicals that showed promise were Dowco 444 and Chevron 20615. Previcur N and fosetyl-AI, as recommended for large trees, did not control the disease on replanted seedlings.
