Abstract: Pulses are cultivated in Konkan region during Rabi season after harvest of Kharif rice, the major threat on this pulses is plant parasite. Cuscuta causes a serious problem in pulses. In view to management of such serious plant parasite, we used different pathogenic suspension viz. Fusarium incarnatum, Alternaria dianthicola and Curvularia pallescens at diverse concentration. Cuscuta gronovii parasitized on green gram host plants were inoculated with different concentration of spore suspension of previous obtained pathogens. The maximum disease severity on C. gronovii were recorded by A. dianthicola @ 2 x 10⁵ and F. incarnatum @ 2 x 10⁵ concentrations parasitizing on green gram and the host plant reaction was found to be immune. At 21 DAI, A. dianthicola @ 2×10⁵ and F. incarnatum @ 2×10⁵ showed maximum disease severity 86.33% and 84.00% respectively. These concentrations of spore suspension of pathogens were act as a mycoherbicide or bioherbicide and applicable to control Cuscuta parasitized on green gram plants effectively.
