After discussing the pros and cons, Auld and Morin conclude that, short term, bioherbicides, "will most easily find a place in irrigated crop production possibly in the tropics or in other situations where the environment can be manipulated, such as in gardens and turf." For future success, "greater understanding of infection and resistance at the biochemical and cellular level and developments in genetic engineering will provide powerful new tools for bioherbicide development," they predict.
