Abstract

Flower extracts and fruit extract of Jatropha curcas, J. glandulufera, J. integerrima and J. gossypofolia were screened in order to study their effect on plant pathogenic bacteria like Erwinia carotovora pv. Carotovora, Pseudomonas aeruginosa, Xanthomonas campestris pv. Citri and Xanthomonas campestris pv. mangiferaeindicae. Degree of variation of antibacterial activity of different parts of Jatropha sp. was observed. It was found that flower and fruit extract of Jatropha sp. were significantly reduced the growth of bacteria. Only flower extract of J. integerrima at 50 µl was proved to inhibitory for growth of Erwinia carotovora pv. Carotovora. At 100 µl concentration flower extract of J. integerrima was found to be most inhibitory against all bacteria. J. curcas fruit extract at 50 µl and 100 µl concentrations was found to be most effective against plant pathogenic bacteria. Fruit extract of all Jatropha species at 50 µl and 100 µl concentration was found to be inhibitory for the growth of Erwinia carotovora pv. Carotovora and Pseudomonas. Xanthomonas campestris pv. mangiferaeindicae growth was only inhibited in fruit extract of all Jatropha species at 100 µl concentration, while, at 50 µl concentration it did not show inhibition
