Fungi are among the main agents of plant diseases, being responsible for major losses in agriculture. The control of these microorganisms carried out using chemical compounds and numerous cases of resistance have already been observed, which makes it necessary to search for alternative methods of management of these pathogens. Therefore, the aim of this study, to evaluate the antifungal potential in plants. Twenty-four (24) plant extracts were tested for their antifungal potential against five plant pathogenic fungi: Sclerotinia sclerotiorum (Ss), Stromatinia cepivora (Sc), Fusarium oxysporum (Fox), Colletotrichum gloesporioides (Cg) and Verticillium dahlia (Vd). For the evaluation of the fungicidal potential, plant extracts were prepared by liquefying the plants in distilled water. The extracts were incorporated into PDA (Potato-Dextrose-Agar) culture medium to a final concentration of 35% and autoclaved. Then, PDA discs colonized by the aforementioned fungi were added to the center of each plate with the respective treatments (plant extracts). When all control treatments (PDA medium without plant extract) had colonized the entire Petri dish, the diameters of the fungal colonies were measured to calculate the Mycelial Growth Inhibition Index (MGI). Tests showed that all these plant extracts have some antifungal activity, ranging from 0 to 100% inhibition. In general, extracts of basil, lavender, guaco, rue, toxic cassava and black plum were the ones that stood out, with MGIs above 50%. New studies are being conducted to evaluate the activity of plant extracts without autoclaving, inhibition of sclerotia formation, to determine the minimum inhibitory concentration, as well as other parts of plants like roots and seeds, mixtures of plant extracts and in vivo antagonism tests.

Six plant extract viz., Datura (Daturastramonium), Eucalyptus (Eucalyptus globulous), Karang (Pongamiaglabra),Neem (Azadirachtaindica), Madar (Calotropis gigantean) and Wild sage (Lantana camara) were evaluated in-vitro by poison food technique @ 3, 6, 9 and 12% concentrations against Alternariabrassicaecausing blight of mustard. The results revealed that all the plant extracts inhibited the percent growth inhibition against test fungus as compared to control. However A.indica was found most efficacious with growth inhibition of (38.7%) followed by E. globulus (36.7%). Some extract such as P. glabra and D. stramonium showed moderate inhibition over control (30.9 and 21.6 respectively). Among all plant extract, C. gigantean showed least (15.3%) inhibition over control against A. brassicae. These plant extracts can possibly be used as management of seedborne pathogenic fungi in an eco-friendly way.

Five fungicides viz., Autostin 50 WDG, Dithane M 45, Greengel 72 WP, Ridomil Gold MZ 68 WG   and Tilt 250 EC exclusively were tested against three pathogenic fungi viz., Colletotrichum gloeosporioides (Penz.) Sacc., Fusarium nivale (Fr.) Ces. and Fusarium sp. associated with Carica papaya L. following poisoned food technique. At 100 ppm  Autostin showed complete growth inhibition of C. gloeosporioides, F. nivale and Fusarium sp., while  Tilt 250 EC showed complete growth inhibition of C. gloeosporioides at the same concentration. These fungicides at 400 and 500 ppm showed complete growth inhibition of F. nivale. Tilt 250 EC showed complete growth inhibition of Fusarium sp. at 300, 400 and 500 ppm. Eight plants extract, viz., Adhatoda vasica, Azadirachta indica, Curcuma longa, Ocimum sanctum, Lantana camara, Tagetes erecta, Thuja orientalis and Vitex negundo were also tested for their  efficacy at 5, 10, 15 and 20% concentrations against these pathogenic fungi. Out of the eight plant extracts, Ocimum sanctum showed highest (88.57%) radial growth inhibition of C. gloeosporioides at 20% concentration. Curcuma longa showed highest (88.55%) radial growth inhibition of F. nivale and Adhatoda vesica showed highest (80.02%) radial growth inhibition of Fusarium sp. at the same concentrations. The present investigation suggests Autostin 50 WDG and Tilt 250 EC as best inhibiting chemical fungicides for C. gloeosporioides, F. nivale and Fusarium sp. Extracts of O. sanctum, C. longa and Adhatoda vesica were found to be superior to other plant extracts tested. Journal of Bangladesh Academy of Sciences, Vol. 42, No. 2, 121-128, 2018
