Abstract

Some rhizobacteria colonize the surface of weed plant roots and secrete phytotoxic metabolites, also known as allelochemicals, that selectively inhibits the growth of weed plants. These allelochemicals are also secreted by some crop plants such as wheat, sorghum, sunflower and many more. The herbicidal impact of microbial (bacteria and fungi) allelochemicals is higher than plant allelochemicals because they don’t have to travel long distances from source to target which reduces their phytotoxicity due to biotic and abiotic soil factors. Therefore, microbial allelochemicals could be potentially exploited for their role as bioherbicides. Bacterial allelochemicals are more phytotoxic to weeds than fungal allelochemicals. The allelochemical metabolites from allelopathic bacteria could be commercialized to control weeds and contribute to integrated pest management systems without having toxic impacts on environment and human health.
