A method for preparing a formulation comprising clomazone, the method comprising the steps of: (i) combining microcapsules having a polymer shell and a core comprising clomazone, a solid carrier and a binder for form a mixture； (ii) forming granules from the resulting mixture； (iii) applying a composition comprising a binder to coat the granules； and (iv) drying the coated granules. Another proposed preparation of a formulation comprising clomazone is provided, the method comprising the steps of: (i) combining microcapsules having a polymer shell and a nucleus comprising clomazone, a solid carrier and a dispersant to form a mix ； (ii) forming granules from the resulting mixture； (iii) applying a composition comprising a dispersant to coat the granules； and (iv) drying the coated granules. Another method of preparing a formulation comprising clomazone is provided, the method comprising the steps of: (i) combining microcapsules having a polymer shell and a core comprising clomazone, a solid carrier and a binder to form a mix ； (ii) forming granules from the resulting mixture； (iii) applying a composition comprising a dispersant to coat the granules； (iv) applying a composition comprising a binder to coat the granules； and (v) drying the coated granules. The invention also relates to granules prepared by the methods and their use in controlling plant growth.L'invention concerne un procédé de préparation d'une formulation comprenant de la clomazone, le procédé comprenant les étapes consistant à : (i) combiner des microcapsules ayant une coque de polymère et un noyau comprenant la clomazone, un véhicule solide et un liant pour former un mélange ； (ii) former des granulés à partir du mélange obtenu ； (iii) appliquer une composition comprenant un liant pour revêtir les granulés ； et (iv) sécher les granulés ainsi revêtus. Un autre proposé de préparation d'une formulation comprenant de la clomazone est proposé, le procédé comprenant les étapes consistant à : (i) combiner de
