Abstract:
Cardamom thrips, <em>Sciothrips cardamomi</em> Ramk. Is one of the important key pest of cardamom in hill and coastal zone of Karnataka. Several newer molecules and botanical insecticides were evaluated against cardamom thrips at farmers field, Mudigere, Karnataka during 2017<strong>-</strong>18. Among the insecticide evaluated, significantly lower mean number of thrips per leaf sheath and panicle was recorded in the treatment fipronil 5% SC @ 1ml/l, acetamiprid 20% SP @ 0.2g/land thiamethoxam 25% WG @ 0.25g/l (0.31, 0.31 and 0.33 no./leaf sheath respectively) and (0.02, 0.05 and 0.07/panicle respectively). However, the bio rational treatments (azadirachtin 1% EC and spinosad 45% SC) were recorded higher mean number of thrips per leaf sheath and panicle, but lower than untreated control. Significantly lower per cent capsule damage were also recorded in the treatments fipronil 5% SC (6.82%), thiamethoxam 25% WG (8.22%) and acetamiprid 20% SP (8.68%). Finally, the marketable yield (kg/ha) was also significantly highest in the treatment Fipronil 5% SC, acetamiprid 20% S Pand thiamethoxam 25% WG (724.2, 722.3 and 704.4 kgs/ha respectively).
