ECOFRIEDLY BIOCOTROL MEASURES FOR XATHOMOAS IFECTIOO VEGETABLE CROPS

Summary Pathovars of Xanthomonas are known to cause diseases on several vegetable and cash crops and are reported to have developed resistance to kanamycin, ampicillin, penicillin and streptomycin. This seriously hinders the management of diseases of crops and agriculture products. To control these bacteria farmers used many synthetic pesticides. But pesticides have made great contribution for quick and effective management of plant diseases and microbial contaminations in several agricultural commodities. Many Xanthomonas Pathovars have acquired resistance to synthetic pesticides. Considering the deleterious effects of synthetic pesticides on life supporting system, there is an urgent need for alternative agents for the management of pathogenic microorganisms. Hence the present study focused to control the phyto pathogen in eco friendly method using green plant extracts. Different parts of a medicinal plant namely Lannea coromandelica was screened for their antibacterial activity on X. campestris . The methanol and aqueous extracts of the leaves and fruits of the plant exhibited significant inhibitory effects against the tested bacteria. Hence in future the selected plant may be used as biocontrol agent to control Xanthomonas infection on vegetable crops.
