Effect of grafting technology on suppression of whitefly {bemisia tabacigennadius) disseminating virus diseases in tomato

Abstract

Grafting technology in tomato with rootstock wild Solanum on the suppression of whitefly disseminating virus diseases was utilized by comparing its performance with two insecticides. The grafted plants resulted in reduced number of whitefly at vegetative stages and was significantly lower than those obtained in Elsan treated and control plants but higher than Ripcord treated and elsan treated grafted plants. Grafted plants could not reduce the white fly population at the early flowering, early fruiting and fruit ripening stages as compared to other treatments. Incidence of leaf curl and purple vein infected plants in grafted and Elsan treated grafted plants were significantly lower at each stage of plant development than in other treatments. The plant damage due to virus diseases were significantly lower at all growth stages in grafted and Elsan treated grafted plants when compared with only insecticide treated plants.
