dc.description.abstractIn this study, we evaluate the productivity impacts of the biological control program (BC) against stemborers in maize production in Kenya. We use production function with damage control function framework to clearly account for the difference in yield-effects of inputs that contribute to plant growth and factors that control damage to plant. The endogeneity concern with pesticide use was accounted for by employing a two-stage least square (2SLS) estimator that subsequently allows deriving the marginal physical product. Findings from the first stage show that the presence of BC agents is associated with a decrease in pesticide use, providing insights on the potential substitution of insecticide by the biological control and the hazardreducing effect of BC on environment. The second stage analysis show significant and positive relationships between maize production and BC suggesting the positive impact of the BC on productivity. The marginal physical product shows that bio-control contributes to substantial increase in maize productivity as each percent point increase in BC level is associated with at least 12 kg/ha gain in maize. Biological control is an advantageous and sustainable policy tool to reduce food insecurity and the potential risks on environment and human health among farmers with poor socioeconomic status.en_US
