Pest management is among the many challenges confronting African farmers today. In Togo, pest attack has been seen as a challenge posed on many vegetable crops producers. In pursuit to contribute to effective vegetables crops protection using local Biopesticide plants, an ethnobotanical survey conducted in the District of Tokpli to collect data from the local population identified five biopesticide plants. Among these plants, Chromolaena odorata, Morinda lucida, Azadirachta indica, and Ludwigia decurrens pure leaves extract significantly reduced the number of Aphtona spp. attacking Okra (Abelmoschus esculentus) plants in the field. Treatment Efficiency of the pure aqueous extract from mixture of leaves of these four plants, applied at the interval of 1 day and 2 days of 14 days were respectively 90% and 81% and were significantly higher than the result obtained with the chemical insecticide LAMBDA POWER applied following the recommendations of the manufacturer which was 79%. © 2020 International Formulae Group.
