Leaf extracts, stem extract, roots extract, latex and oil of Jatropha curcas, J. glandulufera, J. integerrima and J. gossypofolia were screened in order to study their effect on plant pathogenic fungi Alternaria alternata, Aspergillus flavus, Aspergillus niger, Fusarium oxysporum, and Rhizoctonia solani and plant pathogenic bacteria Erwinia carotovora pv. Carotovora, Pseudomonas aeruginosa, Xanthomonas campestris pv. Citri and Xanthomonas campestris pv. mangiferaeindicae.
