“…Rhizotonia (Taub) Butler is one of the most destructive diseases of cowpea in the tropics and subtropics (Chidamboram and Mathur 1975;Dhingra and Sinclair 1977;Reuveni et al 1983). Beside charcoal rot, the pathogens also induce diseases such as dry root rot, wilt, leaf blight and ashy stem blight (Abdon et al 1980;Singh et al 1990).…”

“…M. phaseolina is one of the most disruptive seed and soil-borne pathogens causing diseases in a wide range of hosts (Chidambaran and Mathur, 1975;Dhingra and Sinclair, 1977;Reuveni et al, 1983). It causes charcoal rot disease in water-deficient areas of the world (Das et al, 2008).…”

In this study, surveys were carried out during 2015 and 2016 for wilt and root rot diseases caused by Rhizoctonia solani, Macrophomina phaseolina, Fusarium oxysporum, and Fusarium solani in pepper fields in Adıyaman, Diyarbakır, Mardin and Şanlıurfa provinces of Turkey. The purpose of this study was to evaluate the effects of different inoculation methods (root dip, soil infestation with wheat bran and soil infestation with rice grain) on pathogenicities of R. solani, M. phaseolina, F. oxysporum and F. solani on pepper seedlings. Inoculated pepper seedlings (cv. İnan-3363) were left to grow for three months after transplanting under growth chamber conditions. Inoculation of infective rice-grain was used to test pathogenicity of all four fungi. Root dip inoculation method was used for F. solani and F. oxysporum when the soil was infested with wheat bran method for R. solani and M. phaseolina inoculation. All tested isolates resulted in the stem and root rot, leaf chlorosis and bruising. To test the pathogenicity of fungi, soil infestation with rice grain inoculation was the most suitable method. All tested fungi induced similar foliar symptoms, root rot severity and caused a similar reduction in dry root weights when rice-grain inoculum was used. With other inoculation methods, all pathogens similarly affected root rot severity. Whereas, F. oxysporum was the least virulent pathogen among tested fungi affecting foliar symptom severity; for fresh root and plant weights, and dry root and plant weights; R. solani, M. phaseolina and F. solani were similarly virulent when these parameters were used. The results of the present study may have a useful connotation to monitor pepper seedlings against these pathogens. In conclusion, we recommend rice-grain inoculation to test pathogenicities of R. solani, M. phaseolina, F. oxysporum and F. solanion various pepper cultivars.

“…SRINIVASAN et al (1971) described a technique of obtaining sporulation of fungi by inoculating of these on sterile grass leaves overlaid on water agar. CHIDAMBARAM and MATHUR (1975) used this technique for production of pycnidia of M. phaseolina. As it appears, there are differences in the capacity of the strains to develop pycnidia on any common medium (like sterile grass leaf on water agar), while some of the strains when inoculated on mature tissue of their own host may produce pycnidia.…”
