Chickpea (Cicer arietinum L.) is an important pulse food crop in India. It get infected by many fungi where Alternaria alternata (Fr.) Keissl. was found to be dominant among the diseased samples collected during investigation. From these samples of Alternaria alternata (Fr.) Keissl., wild sensitive (Aa-1) and highly resistant (Aa-11) isolates were identified using Carbendazim and used for passage study. It was seen that growing of Alternaria alternata (Fr.) Keissl. on the medium containing Carbendazim for eight successive passages continuously, increased the resistance constantly till 8th passage. When it was cultured alternately with other fungicides, there was decrease in the development of Carbendazim resistance as compare to Continuous use. When Alternaria alternata (Fr.) Keissl. cultured alternately with other fungicide, there was decrease in Carbendazim resistance. Carbendazim when used alternately with Aliette, Ridomil, Roko, Curzate, there was complete inhibition of the growth of pathogen at 3rd and 4th passages. For mixed passage, it was observed that Carbendazim in mixture with Aliette completely inhibited the growth of pathogen at second passage, followed by Ridomil, Roko, Curzate at 3rd and 4th passages respectively.
