“…Considering the untreated control value of 38 diseased leaflets per plant, the maximal reduction of up to 56% of disease incidence was achieved by A. sativum extract on plants inoculated with X. vesicatoria. Treatments with F. carica fruit extracts were less effective compared to those treated with A. sativum (Balestra et al, 2009).…”

“…vignicola (Thammaiah et al, 1995). The in vivo antibacterial effects of the natural substances contained in the Allium sativum and Ficus carica extracts were identified on tomato plants inoculated with bacterial suspension of X. vesicatoria at 10 5 cfu/ml (Balestra et al, 2009). A. sativum extract reduced disease incidence caused by X. vesicatoria which resulted in 22 diseased leaflets per plant.…”

Since new fungicides are scarce in the market and because of environmental problems, researchers are now emphasizing other alternatives, such as the genetic potential of plants, resistance against pathogens, and the use of biotic and abiotic agents to develop induced or acquired resistance. We investigated the role of resistance-inducing substances (chemicals and plant extracts) in three chickpea cvs. C-44, Pb-91, and Bittle-98 in field experiments against Ascochyta blight disease. These cultivars were selected on the basis of better yield potential shown in previous experiments. Aqueous solution of salicylic acid (SA) at 0.5, 1.0, and 1.5 mM; acibenzolar-S-methyl (ASM) at 0.4, 0.8, and 1.2 mM; and KOH at 25, 50, and 75 mM were applied, whereas Azadirachta indica A. Juss., Datura metel L., and Allium sativum L. plant extracts were applied at 5, 10, and 15%. Disease reduction data was recorded at different intervals from 4 to 14 d after being induced and inoculated with the pathogen. Overall results revealed that significant disease reduction (79.3%) was provided by ASM in the cv. C-44 at 1.2 mM compared with SA, whereas the least significant was KOH. Maximum disease reduction (43.5%) against disease in the plant extracts was observed by applying A. indica leaf extract, but D. metel and A. sativum extracts were not effective. Our findings suggest that enhancing resistance before infecting chickpea plants could be an innovative control method for Ascochyta blight of chickpea.

“…Hans et al (2010) recounted that antifungal activity of oat (Avena sativa) seed extracts exhibited its great potential to prevent and repress the spore germination of P. roqueforti, when applied on rye bread. Moreover Fig leaves extracts exhibiting both antifungal and antibacterial activities against detrimental microbes in foods have been reported previously (Hu et al, 2007;Balestra et al, 2009;Oliveira et al, 2009;Aref et al, 2010).…”

Plants protect themselves by producing phytoalexins and pathogenesis related (PR) proteins in response to different physical and biological stresses as well as against pathological attack. In the present study, chitinase, a PR protein, from peanut seeds was purified to homogeneity by ammonium sulfate precipitation, gel filtration chromatography on Sephadex G-75 column and ion exchange chromatography on Q-Sepharose column. Chitinase was identified as monomeric protein with molecular mass of 30 kDa by SDS-PAGE. Chitinase activity was also evaluated on chitin agar plates showing distinct zones. The optimum pH and temperature of purified chitinase activity were found to be 5.2 and 35°C, respectively. The enzyme was stable within broad pH range of 3.6 to 7.6 and up to 55°C temperature. Amongst the various substrates, acid swollen chitin was found to be the best substrate for chitinase when used at the concentration of 1% exhibiting its high specificity in catalyzing glycosidic bonds between N-acetylglucosamine residues. Chitinase activity of the purified enzyme was inhibited by Hg 2+ and Ag 2+ at 1 mM concentration and enhanced by Ca . The increase in the presence of 2-mercaptomethanol demonstrates the existence of sulfhydryl groups in enzyme active site. The enzyme exhibited a strong inhibitory action towards a variety of fungal species including Fusarium oxysporum, Trichoderma reesei, Aspergillus flavus and A. niger. Purified chitinase showed fungicidal properties against A. flavus on white bread and therefore, could be applied in bakery products to inhibit the formation and growth of fungal colonies.
