Common bean anthracnose caused by Colletotrichum lindemuthianum is an economically important disease in Kenya. The pathogen survives on infected crop debris, seeds and in soil for up to three years. Therefore soil is an important component of study on anthracnose disease epidemiology in beans. Soil sterilization in screenhouse experiments is intended to eliminate the effect of soil pathogenic microbes where reaction of plants to artificial inoculum is being investigated. The objective of this study was to evaluate the effect of soil sterilization on 10 common bean genotypes’ reaction to the anthracnose pathogen under screenhouse conditions.
