Management of major sucking pests on carnation under protected conditions in Kashmir

Abstract

Studies were conducted on management of major sucking pests viz., thrips, aphids and mites on carnation during the year 2017-2018 at Floricultural experimental block, SKUAST-K, Srinagar. Bio-efficacy of entomopathogen, insect growth regulator, botanical and newer molecule of insecticides against thrips (Thrips florum) showed Acetamiprid 20% SP + Nimbecidine 0.03% as most effective in reducing thrips population up to 86.92% and 87.66% in leaves and flowers respectively followed by Fipronil 5% SC (83.02 and 83.80).For aphids (Rhopalosiphum maidis) also similar treatment gave best result followed by Acephate 75% SP + Nimbecidine 0.03%.Although Propargite 57% EC proved least effective against thrips and aphids both on leaves and flowers but ranked best with respect to mites, Tetranychus urticae (85.92% and 81.13%) in leaves and flowers respectively. Benefit Cost Ratio (BCR) was highest in Acetamiprid 20% SP + Nimbecidine 0.03% (1:1.88).
