In Vivo Evaluation of Fungicides on Fusarium Equiseti Follar Blight of Jatropha Curcas L.

Three fungicides; Mancozeb, Mancozeb+ Carbendazim and Imidacloprid + metalaxyl-m + tebuconazole were evaluated in vivo at three levels (manufacturers recommended rate, half the recommended rate and one and half the recommended rate) on an isolate of Fusarium equiseti responsible for leaf blight on Jatropha curcas plant in a Complete Randomized Design. All the fungicides affected the mycelia growth of Fusarium equiseti at different levels. However, Mancozeb + carbendazim on one hand and imidlacloprid + metalaxyl-m + tebuconazole on the other hand proved to be the most effective on Fusarium equiseti when applied at manufacturers recommended rate, while mancozeb when used alone was only effective on the fungal pathogen at one and half recommended concentration.
