Abstract

The effect of 6 concentrations of Benomyl and Rovral Ts(35% Iprodione & 15% Carbendazime) fungicides were investigated on growth rate of Fusasrium solani in PDA culture with 3 replications . The means of colony diameter of the fungus in 3ppm of Benomyl , Rovrat and control treatments were 21.66,21. 33 and 85.5 respectively . These two fungicides reduced growth of the pathogen up to 75.25 and 75.05% respectively. Benomyl and Rovral decreased the germination of the spores at rate 63.5 and6&04 percent in vitro. 100 ppm concentration of the fungicides were used in infested soil in a randomized completely design with three replications. Results indicated that benomyl and Rovral decreased black root rot up to 62 and 69% respectively. The use of these fungicides in (infected) soil increased height and fresh weight of chickpea shoots comparing with those of infested soil with the pathogen , but in healthy control these fig were greater than other treaments.
