INTEGRATED MANAGEMENT OF WHITEFLY; THE VECTOR OF OKRA YELLOW VEIN MOSAIC VIRUS THROUGH DIVERSE GERMPLASM AND PLANT EXTRACTS

Abstract

The present research was conducted to study the population incidence of whitefly (Bemisia tabaci) on 15 okra cultivars using four plant extracts with a control for its management under field conditions. The data regarding to population incidence of whitefly was recorded. Minimum whitefly population was recorded on Sabz pari (7.67%) and Sanam (9.22%) followed by Kiran (17%), Green wonder (17.33%), Okra-1548 (19%), Click-5769 (20.33%), A. Selection (20.44%), Laxmy (20.78%), Okra-7100 (21%), Pusa Swani (21.89%), Pk-0k-1 (23.44%), Pmf Beauty (26.11%), Okra-7080 (26.78%), Jk-tetra-6 (28.78%) and Super star (31.11%). Among plant extracts Azadirachta indica was 24.4% effective as compared to Eucalyptus camaldulensis (25.9%), Melia azedarach (27.1%), Cassia fistula (28.1%) and control (31.9%) and minimum whitefly was recorded at okra-7100 (26.8%) followed by laxmy (26.8%), okra-7080 (27.5%), jk-tetra-6 (28.2%) and pmf beauty (28.2%). Azadirachta indica and variety okra-7100 performed better among all extracts and varieties.
