Abstract
Plant protection through synthetic chemicals contributed significantly in reducing
losses due to disease and thereby increased agricultural production. However,
chemicals share to environmental pollutions through air, water, soil and by induction
of resistance amongst the pathogens, currently caused wide spread concern and hence
the need to look for an alternative safer means for plant disease is felt greater now
than ever before. Natural plant product components can replace synthetic chemicals
effectively. Four strains of bacterial pathogens viz., Xanthomonas campestris pv.
campestris, Xanthomonas axonopodis pv. cyamopsidis, Xanthomonas axonopodis pv.
citri and Pseudomonas solanacearum were isolated from cabbage, cluster bean, citrus
and potato respectively. Seven partially purified plant product components were
screened for their efficacy in inhibiting the growth of the above pathogens by using
disc diffusion techniques at 500, 1000 and 2000 ppm concentration. The maximum
inhibiting zone was obtained from Mahua flower and Satyanashi components
effective only against Pseudomonas strains at 2000 ppm but these were not effective
against three Xanthomonas strains.
