  14. 14. Conventional biopesticides
  15. 15. The problem with conventional biopesticides conventional biopesticide formulation problems costs and quantities involved for mass production are problematic logistically and economically not maize bran soil feasible for farmers application problems abiotic factors greatly reduce field performance topical pounded rhizomes pheromone traps
  16. 16. Conventional biopesticides as artifical endophytes? conventional biopesticide artificial endophyte costs and quantities involved for very low quantities needed and mass production are the technique is easily problematic integrated in a commercial lab logistically and economically not farmers do not need to apply the feasible for farmers product abiotic factors greatly reduce the product is protected inside field performance the plant topical systemic

  47. 47. Post-hoc impact survey of 1,055 farmers in Kenya, Burundi and Uganda quantifying drivers of (non) adoption effect on productivity, income, income distribution Kenya: “We find that female farmers are more likely to adopt TC and farm size does not necessarily influence adoption. Surprisingly, we find a negative coefficient for peer group effects on TC adoption.” MSc thesis (Mukamba, 2010) MSc thesis (Musuuza, 2010) PhD thesis (Sentambu, 2010)
