Lambda-cyhalothrin is a pyrethroids insecticide used in Burkina Faso for crop protection. This insecticide efficacy is well known by vegetable farmers. However, no information is available on the persistence of lambda-cyhalothrin in soil under Burkina Faso climate conditions. The objective of this study was to determine the persistence of lambda-cyhalothrin in vegetable soil in Burkina Faso. Materials and Methods: The first experiment to determine the persistence of lambda-cyhalothrin was carried out under laboratory conditions in sterile and non-sterile soil to evaluate the microbial contribution to degradation. The second experiment has been done in soil with and without manure to evaluate the contribution of manure to lambda-cyhalothrin degradation. Results: During the incubation, 73.2% of lambda-cyhalothrin degraded in 7 days in non-sterile soil as opposed to 12.0% in sterile soil during the same period. During all the incubation period (20 days), lambda-cyhalothrin degradation was still slow in sterile soils (64%) compare to the degradation in non-sterile soil (83.7%). The half-life of lambda-cyhalothrin in sterile and non-sterile soil was 27.36 and 14.33 days, respectively. The results of the contribution of manure to lambda-cyhalothrin degradation have showed that the dissipation in soil in the presence of manure is higher (26.25%) than the dissipation without manure (21.5%) during the first 7 days and from 8-20 days after incubation. Conclusion: Microorganisms, abiotic factors and soil organic manure contribute to the dissipation of lambda-cyhalothrin in the soil.]]>Gu, B.G., H.M. Wang, W.L. Chen, D.J. Cai and Z.J.
