How to manage thrips in onion crop

  • Thrips are small and soft-bodied insects and can be found on the upper surface of leaves but usually on the lower surface of leaves. 

  • With their sharp mouthparts, they suck the sap of the leaves, which causes the leaves to turn brown on the edges. 

  • The affected plant appears dry and the leaf becomes discoloured and curls upwards. This insect is the cause of Jalebi disease in onion crops.

  • For the control of thrips it is necessary to use different chemicals for every spray.

Control Measures

  • For biological control, spray Brigade B (Bavaria bassiana 1.15% WP) @ 1 kg/acre @ 150 -200 liters of water.

  • To control this pest, Spray Novalaxam (Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC) @ 60 ml or Jump (Fipronil 80% WG) @ 30 gm + Silicomaxx @ 50 ml + Novamaxx (Gibberellic Acid 0.001%) @ 300 ml, per acre  @ 150 to 200 liters of water.
