ABSTRACT
Sunflower (Helianthus annuus) is a key oilseed crop with 15-21% protein and 50% oil content, ranking fourth globally and third in Pakistan. Pakistan currently produces only 18% of its edible oil, with sunflower contributing 11%. Sunflowers are cultivated on 151,000 acres, yielding 87,000 tonnes of seeds and 33,000 tonnes of oil. The Present study evaluated the effectiveness of conventional insecticides and indigenous plant extracts against sucking insect pests (Whitefly and Jassid) on sunflowers. Two different concentrations (50 ml/L and 100 ml/L) of botanical extracts of Azadirachta indica, Eucalyptus globulus, Nicotiana tabacum, Piper nigrum, and Allium sativum were tested. A. indica caused maximum mortality (58.93% and 60.48%, respectively) of whitefly and Jassid @ 50ml/L after one week of treatment. At 100ml/L, A. indica caused 80.16% mortality of whitefly and 82.83% of jassid. Among synthetic insecticides, Flonicamid caused 93.33% mortality of whitefly and 92.93% of Jassid after one-week of exposure period. The integration of botanical extracts with synthetic insecticides in Integrated Pest Management (IPM) module can improve pest control and sunflower yield.
