Profitable maize production in Nigeria is hinged on chemical control of insect pests with its attendant problems. The use of synthetic insecticides for the control of field and stored insect pests has created many problems such as environmental hazards, pest resistance which necessitated a search for alternative means of controlling fall armyworm (Spodoptera frugiperda) with plant products. Field experiments were conducted at Teaching and Research farm of Department of Agronomy, Faculty of Agriculture, Federal University of Kashere, Gombe State, Nigeria to compare the efficacy of four plant extracts on fall armyworm (S. frugiperda) on maize (Zea mays L.) under rain fed conditions in 2024 and 2025 cropping seasons. A randomized complete block design in three replications was used. There were five treatments (desert palm leaves , Balanites aegyptiaca Del; mahogany leaves, Khaya senegalensis L.,Jatropha leaves, Jatropha curcas L., Neem leaves, Azadirachta indica A. Juss and a standard check Lambda-cyhalothrin 2.5 EC ).  The results showed that neem leaf extract (NLE) was found to be effective for the control of fall armyworm on maize in the study area. Fall armyworm percentage incidence, number of larvae/plant, and leaf area damaged were significantly reduced at 20% w/v while plant height, number of leaves/plant, stem girth, leaf area, cob weight, number of seeds/cob, seed weight and grain yield were significantly (P<0.05) increased in both 2024 and 2025 cropping seasons in the study area. The plot treated with Lambda-cyhalothrin 2.5 EC gave the best results which was at par with NLE followed by BLE and MLE while the growth and yield attributes of maize were significantly reduced when the maize crops were treated with JLE during the study period. It can therefore be safely concluded that neem leaf extract at 20% w/v was effective in controlling fall armyworm on maize and was at par with the Lambda-cyhalothrin 2.5 EC. This suggest that application of neem leaf extract at 20% w/v could therefore be used as an eco-friendly and environmentally safe option for the control of fall armyworm infestation on maize in the study area.
