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.
