The leaf surface fungal flora is subjected not only to the influence of the host, but also to its own factors. An important aspect is the production of self incubatory products as well as self stimulating products by the fungal organisms present on the leaf surface. Amongst microorganisms fungi can be a sole cause of spoilage and substantially decrease the quality, grade and price of plant materials. In the present studies leaves were found mainly infected with Aspergillus niger, A. favus , Curvularia lunata, Chaetomium globosom, Penicillum citrinum and Fusarium oxysporum as these six were found on the leaves throughout the study and their incidence degree were quite high.

Seeds are usually infected by microorganisms and pests during storage, causing deterioration and reduction in the nutritive and market value of these seeds. In this study, the proximate composition of Vigna unguiculata seeds inoculated with different fungal organisms was determined to ascertain the level of deterioration caused by fungi on the seeds. The fungi used in the study were Botryodiplodia theobromae, Fusarium oxysporum, Rhizopus stolonifer and Aspergillus niger. There was a significant increase (p<0.05, 0.008) in the protein content of seeds inoculated with fungi. Fusarium oxysporum (29.45%) caused the highest increase in protein followed by Aspergillus niger (28.14%), Botryodiplodia theobromae (27.85%) and Rhizopus stolonifer (27.50%). The increase could be attributed to the proteineous content of the fungal mycelia. There was a significant increase (p<0.05, 0.005/0.014) in moisture and ash content of inoculated seeds respectively. Fusarium oxysporum caused the highest increase in ash (7.93) while Rhizopus stolonifer (5.4) caused the lowest increase. The increase in ash content is due to the presence of minerals like potassium and phosphorus in the mycelia of the fungi. There was a significant decrease (p<0.05, 0.019) in the carbohydrate, lipid, fibre and dry matter content of fungi-inoculated seeds when compared with the control. Fusarium oxysporum (36.6) caused the highest decrease while Rhizopus stolonifer (43.2) caused the lowest decrease in dry matter of inoculated seeds. Decrease in dry matter may be as a result of production of enzymes by these fungi.

Les huiles de Jatropha curcas communément appelé pourghère et de neem (Azadirachta indica A. Juss), sont testées comme alternatives aux pesticides chimiques dans l’optique d’y déceler de potentiels effets fongicides tout en préservant l’environnement. Les effets des deux huiles végétales sont comparés à ceux de deux fongicides conventionnels, la griséofulvine 250 mg et la nystatine ainsi que l’alcool 95°, sur cinq champignons phytopathogènes (Aspergillus flavus, Aspergillus niger, Curvularia lunata, Fusarium oxysporum et Rhizopus oryzae). Les observations ont porté sur la mesure du diamètre de la zone d’inhibition exercée par les différentes substances inhibitrices à travers les milieux gélosés. Le dispositif expérimental appliqué a été celui du bloc complètement randomisé de Fisher avec huit répétitions. Les moyennes des diamètres de la zone d’inhibition sont respectivement de 26,51 mm pour la nystatine, 14,53 mm pour la griséofulvine, 4,53 mm pour l’huile de neem, 3,05 mm pour l’huile de jatropha, et 0,00 mm pour l’alcool 95°. L’huile de neem a eu un effet inhibiteur net sur la croissance de l’ensemble des champignons testés. En revanche, l’huile de jatropha a exercé un meilleur contrôle de la croissance des espèces Aspergillus flavus, Aspergillus niger et Rhizopus oryzae. Les deux huiles pourraient être recommandées dans la protection des denrées stockées, notamment les céréales.Mots clés : Extraits végétaux, effet fongicide, zone d’inhibition, lutte alternative.

Juss) were tested as alternatives to chemical pesticides in a view to finding some potential fungicide effects harmless to environment. The effects of the two natural oils were compared with those of two conventional fungicides, griseofulvin 250 mg and nystatin and also alcohol 95° on five phytopathogenic fungi (Aspergillus flavus, Aspergillus niger, Curvularia lunata, Fusarium oxysporum and Rhizopus oryzae). Observations consisted in measuring the diameter of the zone of inhibition by different substances through the agarose medium. The experimental device applied was the Fisher completely randomized bloc with eight repetitions. Means of inhibition zone diameters were respectively de 26.51 mm for nystatin, 14.53 mm for griseofulvin, 4.53 mm for neem oil, 3.05 mm for jatropha oil, and 0.00 mm for alcohol 95°. The neem oil showed good inhibition effect on the growth of the whole set of tested fungi. In contrast, jatropha oil exhibited a better fungal growth control on Aspergillus flavus, Aspergillus niger and Rhizopus oryzae species. Thus, these two vegetable oils could be recommended in cereal protection in postharvest.Keywords: Vegetal oils, fungicide effects, inhibition zone, alternative control.

In continuation of our search for efficient pest control natural products from the flora of the South Eastern Sub-Himalayan biodiversity region, we have investigated wild edible Piper pedicellatum C. DC (Piperaceae) from Arunachal Pradesh, India against five important plant pathogenic fungi through an activity guided method, and a new compound, pedicellamide, was isolated. The structure was determined on the basis of extensive spectroscopic studies and confirmed by X-ray crystallography. The compound exhibited antifungal activities against the phytopathogenic fungal organisms Rhizoctonia solani (MIC 38.4 ± 1.6 μg/mL), Fusarium oxysporum (MIC 29.7 ± 0.8 μg/mL), Aspergillus niger (MIC 48.6 ± 0.7 μg/mL), Puccinia gramini (MIC 46.8 ± 1.4 μg/mL) and Curvularia lunata (MIC 49.1 ± 0.1μg/mL). Additionally, the antioxidant potential of the compound was estimated by DPPH, ABTS and FRAP assay and found to be 2.87 ± 0.20, 2.19 ± 0.13 and 3.96 ± 0.17 VCEAC (μM/g), respectively.

Introduction: Fungi live everywhere in the environment, most of them are not dangerous, but some types of fungi can be harmful to humanhealth. The medicinal plants contain many antimicrobial components that make them recently used as powerful drugs. The aim of the present investigation was to examine the antifungal potential and minimum inhibitory concentration (MIC) of three plant extract: Aloe vera gel, cinnamon (Cinnamomum zeylanicum) and turmeric (Curcuma longa) against three fungal species: Aspergillus niger, Candida albicans and Fusarium oxysporum. Materials and Methods: The plant materials were extracted using solvents DMSO and ethanol and then were tested against the selected fungal isolates using well diffusion method. Results and Discussion: Antifungal activity of Aloe vera against Aspergillus niger showed MIC value of 25% whereas for Candida albicans and Fusarium oxysporum the MIC obtained was 100%. Both cinnamon and turmeric showed maximum potency against Aspergillus niger, Candida albicans and Fusarium oxysporum at highest MIC value of 100 %. The degree of inhibition increased correspondingly with increasing concentrations of the plant extracts. Conclusions: the tested plant extracts have an antifungal activity and could be used as alternative drugs.

The present study was conducted to determine antifungal activity of three different concentrations (5, 10, and 15%) of cow urine against three fungal pathogens (Fusarium oxysporum, Rhizoctonia solani, andSclerotium rolfsii) isolated from infected plants of Methi and Bhindi that showed symptoms of damping off and wilting disease by poison food technique. The extent of growth of test fungi in plates poisoned with cow urine was lesser when compared with the control plates. Among these concentrations cow urine at 15% concentration was most effective. When the three fungal organisms were compared, maximum growth suppression was observed inFusarium oxysporum(78.57%) at 15% concentration of cow urine followed byRhizoctonia solani(78.37%) andSclerotium rolfsii(73.84%). Finally we concluded that the cow urine has antifungal activities and the inhibitory activity can be used in the control of fungi. The nutritional effect of cow urine on plant growth was also tested withTrigonella foenum-graecum(Methi) andAbelmoschus esculentus(Bhindi) plants and the chlorophyll and protein content was also estimated.
