ABSTRACT

Eleven fungicides of four different categories viz., six systemic, two non-systemic and three mixed formulations and Six herbicides at their three different concentrations were tested in vitro by poisoned food technique for evaluating their efficacy against M. phaseolina causing root rot of chickpea. Among all concentrations tested, the higher concentrations of each of fungicides and herbicides produced maximum growth inhibition of the pathogen. From tested fungicides, carbendazim (Bavistin 50WP), tricyclazole (Beam 75 WP), propiconazole (Tilt 25 EC), Quintal 50%WP (carbendazim 25 % + iprodine 27 %) and Sixer 75WP (carbendazim 12% + mancozeb 63%) at all three concentrations completely inhibited growth of the pathogen and proved to be highly toxic to the pathogen. Among all herbicides tested, pendimethalin (Stomp 30 EC), oxyflourfan (Galagan 23.5 EC) and alachlor (Laso 50 EC) were proved to be effective in inhibiting the mycelial growth of the pathogen.
