Abstract

Mancozeb is a wide spectrum contact fungicide for use on anumerousvariety of vegetables and ornamentals worldwide. In this study, the physicochemical properties of six commercial mancozeb (80%) wettable powder products, Anadol, Dithane Dicozeb, Mancozan, Manco and Tridex, were determined as described by Collaborative International Pesticides Analytical Council (CIPAC) and World Health Organization (WHO). The antifungal activity of mancozeb products was evaluated against four plant pathogenic fungi, namely Alternaria alternata, Phytophthora infestans, Fusarium oxysporum and Pythium debaryanum in vitro. The results of physicochemical tests showed that all mancozeb products passed suspensibility and wettability tests. In foam formation test, all the products passed the test except Anadol which failed in both CIPAC and WHO methods, while Manco failed in WHO method. Among the six tested mancozeb products, Tridex was the only one that passed alkalinity test. Although the six mancozeb products were formulated as wettable powder with the same concentration of active ingredient (80%) the antifungal activity of the products were markedly differed. Tridex exhibited the strongest antifungal activity against three of the four tested fungi A. alternata, F. oxysporum and P. infestans, while, Dithane was the most effective fungicide against P. debaryanum. A. alternata was the most sensitive fungi to all of the tested fungicides, while F. oxysporum and P. debaryanum displayed the lowest sensitivity. The results of this study indicated that some of mancozeb commercial formulations in the Egyptian markets were not matched with CIPAC and WHO specifications and the antifungal activity was strongly varied based on the manufacturing company.
