Six pathogenic fungi, namely Aspergillus flavus Link., A. niger van Tieghem (Type-I)., Curvularia lunata (Wakker) Boedijn, Fusarium moniliforme var. subglutinans Wr. & Reink., Fusarium sporotrichioides Sherb., Mem. and Rhizoctonia solani J.G. Kuhn were isolated from cotton seeds. Five fungicides viz., Acrobat MZ, Autostin 50 WDG, Capvit 50 WP, Nativo 75 WP and Thiovit 80 WG were selected to evaluate in vitro efficacy at 100, 200, 300, 400 and 500 ppm concentrations against pathogenic fungi following poisoned food technique. Out of 5 fungicides Nativo 75 WP showed the complete growth inhibition of above mentioned six pathogenic fungi at all the used concentrations. Autostin 50 WDG showed complete growth inhibition of all tested pathogenic fungi except Curvularia lunata. Leaf extract of five angiospermic plants viz., Adhatoda vasica, Aegle mermelos, Azadirachta indica, Datura metel and Psidium guajava were selected to evaluate in vitro fungitoxicity at 5, 10, 15 and 20% concentrations against the test pathogens. At 20% concentration, out of the 5 plants extracts A. indica was found to be most active to inhibit the growth of Aspergillus niger (Type-I) (65.56%) and Fusarium moniliforme var. subglutinans (75.00%), Psidium guajava were most active against A. flavus (81.29%) and Curvularia lunata (72.23%), and Datura metel was most active against Fusarium sporotrichioides (64.77%) and Rhizoctonia solani (42.44%).

Fifty five angiospermic plants were selected for evaluating the effect of their aqueous extracts on the in vitro vegetative growth of Fusarium moniliforme Sheldon. Extracts of 17 plants showed varied degrees of inhibitory effects on the test pathogen. For instance the leaf extract of Lawsonia inermis showed maximum inhibition (60.65 %) followed by roots of Asparagus racemosus (50.59 %). The possibility of using these plant extracts in seed treatment to control bakanae disease of rice is suggested. Antifungal property of leaves of Andrographis paniculata and Lagerstroemia speciosa against bakanae disease is reported here for the first time.

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

Antifungal potentials of nine fungicides and eight plant parts extracts were tested in opposition to Fusarium oxysporum Schlecht. and F. solani (Mart.) Sacc. – the two pathogens, isolated from wilted roots of brinjal plants. Efficiency gradients observed in the present study expressed that Bavistin and Tall were the best inhibiting agent against the in vitro growth of the test pathogenic fungi. Among aqueous extracts of eight plant parts significant inhibition of the growth of the pathogens was observed with Azadiracta indica (leaf), Zingiber officinale (rhizome) and Asparagus racemosus (root) at 20% concentration.

Anthracnose and blight were recorded on Houttuynia cordata Thunb. during April 2013 to December 2013. The isolated fungi from the symptomatic plants were identified as Alterneria alternata (Fr.) Keissler and Colletotrichum gloeosporoides (Penz.) Sacc. Ethanol leaf extracts of five plants viz.,Azadirachta indica L., Citrus limon L., Datura metel L., Sennaalata L. and Tagetes erecta L.were evaluated against the pathogenic fungi A. alternata and C. gloeosporoides at 5%, 10% and 20% concentrations in vitro. A. indica recorded as good inhibitor against the test fungi followed by C. limon, S. alata, D. metel and T.erecta. In vivo treatment also showed that A.indica is the most effective in controlling diseases at 10% concentration. The plants treated with A. indica were fresh and healthy up to one month of observation.J. Asiat. Soc. Bangladesh, Sci. 42(1): 41-48, June 2016

A number of 2,3-di-O-acyl derivatives (6-11) of methyl 4-O-acetyl-a-Lrhamnopyranoside (5) obtained by using various acylating agents were screened for in vitro antifungal activity against four plant pathogenic fungi, viz., Alternaria alternata, Curvularia lunata. Fusarium equiseti and Macrophomina phaseolina. These compounds were also screened for in vitro antibacterial activity against ten human pathogenic bacteria, viz., Bacillus subtilis, Bacillus cereus, Bacillus megaterium, Staphylococcus aureus, Escherichia coli, INABA ET (Vibrio), Pseudomonas species, Salmonella paratyphi, Shigella dysenteriae and Salmonella typhi. The study reveal that these 4-O-acetyl-?-L-rhamnopyranoside derivatives are more prone towards antifungal activities than that of antibacterial activities.
