Asad Chaudhary, Khan MA and Bilal Yousaf

Four plants extract i.e. Azadirachta indica (neem), Allium sativum (garlic), Zingiber officinale (ginger) Allium cepa L (onion) were evaluated to manage OYVMV and its vector. For this purpose four Okra varieties Sabz pari, Pahuja, Pusa sawani and Lush green was sown under RCBD design. Data obtained from vector population and disease incidence was analyzed through ANOVA. Sabz pari was found moderately resistant. Pahuja showed tolerant behavior while Lush green and Pusa sawani showed moderately susceptible and susceptible response respectively. Among four plants extract Azadirachta indica (Neem) at 5% concentration was effective as compared to control and other extracts in reducing the whitefly and OYVMV disease incidence under field condition.
