ABSTRACT

The objective of present study was to evaluate the effect of copper hydroxide and flare at three concentrations (0.1, 0.2 and 1%) and naphthalene acetic acid, salicylic acid, copper hydroxide alone and in combination (Flare + salicylic acid) at 0.75, 1 and 1.5% concentration against Xanthomonas axonopodis pv. citri in lab and greenhouse conditions respectively. Results showed that in lab condition maximum inhibition of bacterial growth was expressed by combination of flare and copper hydroxide, followed by Flare, copper hydroxide over control while in case of greenhouse experiment minimum disease incidence was expressed by combination of Flare + salicylic acid after 5, 10 and 15 days interval followed by flare, salicylic acid, naphthalene acetic acid and Cu(OH)2 as compared to control.
