In Morocco, vicia faba is considered the most important legume for both food and feed. However, the ravages caused by pathogens remain hardly controlled. The objective of the present study is to evaluate the efficacy of Urtica dioica and Capsicum frutescens’ extracts in protecting broad beans against Bruchus rufimanus infestation. To this end, the research was conducted at the National Institute for Agricultural Research in Meknes (INRA) during the 2015-2016 crop years. The experimentation was conducted in pots with four replicates to evaluate the efficacy of aqueous extracts of urtica dioica and capsicum frutescens on five varieties of Vicia faba beans. The cultures were spread with the aqueous extract of these two plants from the beginning of flowering to maturity. The results of the study showed that the aqueous extract of c. frustescens at 100g/l dose, decreased the rate of infestation of beans by bruchids by 16.35% while for the other treatments, no decrease was recorded. In addition, an increase in yield was notified for the aqueous extract of u. dioica at the dose of 100g / l with a percentage of 4.96% and a pourcentage of 8.18% at the dose of 200g/l.

Abstract: (french)
Au Maroc, vicia faba est considérée comme la légumineuse la plus importante tant pour l’alimentation humaine qu’animale. Toutefois, les ravages causés par les pathogènes restent limitativement contrôlés. La présente étude a ainsi pour objectif d’évaluer l’efficacité des extraits d’Urtica dioica et de Capsicum frutescens à protéger les fèves contre l’infestation par les bruches (Bruchus rufimanus). A cette fin, les travaux de recherche ont été menés au sein de l’institut National de Recherche Agronomique de Meknès (INRA) durant l’année culturale 2015-2016. Le dispositif expérimental a été conduit dans des pots avec quatre répétitions pour évaluer l’efficacité des extraits aqueux d’urtica dioica et de capsicum frutescens sur cinq variétés de fèves et fèveroles (Vicia Faba). Les cultures ont été pulvérisées par l’extrait aqueux de ces deux plantes dès le début de la floraison jusqu'à la maturité. Les résultats de l’étude ont montré que l’extrait aqueux à base de c. frustescens pour la dose 100g/l, a diminué de 16.35 % le taux de l’infestation des fèves par les bruches alors que pour les autres traitements, aucune diminution n’a été enregistrée. Par ailleurs, une augmentation du rendement a été enregistrée pour l’extrait aqueux à base d’u. dioica pour la dose 100g/l avec un pourcentage de 4.96 % et de 8.18% pour la dose 200g/l.
