In Burkina Faso, current pest control relies on synthetic chemical pesticides, which could negatively impact the environment and develop some resistances when used excessively. This study used three biopesticides (Neem oil, Bio k16 and Biopoder) to examine their effectiveness on fall armyworm (FAW) control in maize crop. The study was conducted in the central region of Burkina Faso using a randomized Fisher block design with 5 treatments in 4 replicates. The applied treatments were: T0 (control), T1 (Neem oil), T2 (Bio K16), T3 (Biopoder) and T4 (Emacot 019EC). The efficiency of these biopesticides in controlling FAW was compared with that of the Emacot 019EC in maize crop. The results showed that the biopesticides significantly reduced the infestation rate, the live larvae density and the number of corncob damaged. However, Emacot 019C was the most effective pesticide. Among the three biopesticides, neem oil was the most effective followed by Bio K 16 and Biopoder respectively. This study needs to be deepened in other sites and in taking into account the economic aspect.
