Kinnow mandarin (Citrus reticulata Blanco) is a valuable fruit crop mainly grown in the North Indian states of India due to its high-quality juice content. Psylla (Diaphorina citri Kuwayama), whitefly (Dialoeurodes Ashmead), sooty mould (Capnodium citri) and dieback (Colletotrichum gloeosporioides) pests are most important biotic constraints affecting yield up 70 percent. To manage these pests, farmers often use mixture non-label claim pesticides (quinalphos 25%EC, lambda-cyhalothrin 2.5%EC, diafenthiuron 50%WP, chlorantraniliprole 18.5%, cymoxanil 8% + mancozeb 64% WP, etc.) without achieving desired effect. Hence, area-wide implementation Integrated Pest Management (IPM) strategy was implemented during 2021-2023 covering 5 villages at Hisar, Haryana. Among IPM strategy, installing yellow sticky traps @ 20/ha, neem seed kernel extract spray 5%, imidacloprid 17.8SL 0.3% reduced psylla populations. The 1% starch dipping infected fruits bleaching solution 0.1% severity disease. Pruning destruction dead twigs followed by copper oxychloride 50 WP were found very effective too. lowest average population recorded T1-IPM compared T2-farmer practice T3-control, respectively. Minimum disease noticed while highest T3-control. Population dynamics psylla, mould, severity, Area Under Diseases Progress Curve (AUDPC) vary 11th 52nd standard meteorological week (SMW). They observed be T3-control treatment, T1-IPM. natural enemy's populations (Coccinellid, Chrysoperla, spider) T1-IPM, then treatment. B: C ratio validated strategies can adopted growing as an economically viable option for management whitefly, pests.
