Abstract: The effects of Allium sativum and Allium cepa extracts on the Fall Armyworm and growth of Babycorn (Variety SG 18) under greenhouse conditions were evaluated. Treatments were laid out in a Randomized Complete Block Design (RCBD) with 3 replications. The factors included solvents used: Dichroloromethane (DCM), Methanol (Me), Distilled water (Di) and type of plant used: Allium sativum and Allium cepa. The positive and negative controls were Coragen SC 200 (Co) and distilled water (Di), respectively. Data collection and analysis was done using appropriate procedures. The extraction yield was highest with Methanol for A cepa and distilled water for A sativum, while DCM yielded the least for both plants. Saponins, glycosides, alkaloid and tannins were present in all the plant species, but their presence was influenced by the solvent type. Flavoniods were only present in DCM-A sativum extract whose content was 5.2378 ± 0.1094 mg/mL. DCM and Methanolic extracts of A cepa and A sativum were as effective as Coragen SC 200 against FAW larvae as opposed to distilled water extract. No significant differences were noted for plant height and leaf numbers. Further evaluation should be done towards making commercially available and effective insecticide for integrated FAW management.
