Monitoring through sticky traps noticed that maximum mean catches of 46.72 and 15.91 thrips and aphids/trap during the month of July. There was positive correlation between population of sucking pests with temperature but negative correlation with RH. The acetamiprid 20% SP + Nimbecidine 0.03% treatment was found effective against thrips (86.92 and 87.66% in leaves and flowers) and aphids (87.89 and 89.01% in leaves and flowers). With respect to mites, Propargite 57% EC was found effective (85.92 and 81.13% in leaves and flowers). Benefit Cost Ratio was worked out highest in Acetamiprid 20% SP + Nimbecidine 0.03% (1:1.88).
