Formulation of a bioherbicide ideally should result in a product that has low cost, long shelf‐life, ease of application and efficacy. Formulation persists as a constraint to commercial development of many potential bioherbicides often because dew dependence in fungi limits their efficacy under dry‐land conditions. This has not been a problem with several commercial bioherbicides because they are used in irrigated systems or applied as wound inoculations. Thus, reduction in dew dependence is a principal aim in the formulation of many potential bioherbicides. In the present paper, formulation research attempting in part to overcome this problem via the development of novel solid and liquid formulations is described. Solid formulations typically must be able to survive in the field and await suitable conditions before becoming activated. Liquid formulations have the potential to produce infections soon after application provided they remain moist on the target plant surface. Several attempts to improve water‐holding capacity in liquid formulations have been examined. The use of multiple emulsions of water in oil in water has recently shown promise.
