Fifteen fungicides and two commercial formulations of the insecticide, dicrotophos, were investigated for In vitro fungitoxicity against mango anthracnose pathogen, Colletotrichum gloeosporioides. Among the fungicides tested, the pathogen was extremely sensitive to the thiophanate, the benzimidazoles and two of the N-trichloromethylthio group of fungitoxicants which exhibited ED50 of less than 5 µg/ml. The dithiocarbamates varied in their degree of toxicity, with ED50 ranging from 100 µg/ml to 580 µg/ml. The two miscellaneous fungicides, chlorothalonil and iprodione and the two insecticides showed extremely low and negligible fungitoxicity, respectively. Similarities and differences between and within groups of fungicides tested are further discussed in relation to their chemical structures, biochemical modes of actions and formulations.
