Description

FIELD OF THE DISCLOSURE Described herein are compositions including encapsulated bixlozone and non-encapsulated bixlozone. Also described herein are methods of preparing the compositions. Also described herein are methods for controlling undesirable vegetation with the compositions. BACKGROUND OF THE DISCLOSURE Bixlozone compositions often balance crop safety and efficacy. Generally, encapsulated bixlozone is more selective, and therefore safer, but less efficacious compared to non-encapsulated bixlozone. Further, target crop injury and off-target crop injury, from spray drift, for example, must be considered. These balancing considerations limit formulations including bixlozone. BRIEF DESCRIPTION OF THE DISCLOSURE It was discovered herein that compositions including both encapsulated bixlozone and non-encapsulated bixlozone are both safe and efficacious. A formulation including a mixture of encapsulated bixlozone and non-encapsulated bixlozone results in a surprising enhancement in safety such that off-target crop injury in the absence of a safener is comparable to off-target crop injury in the presence of a safener. In other words, a ZC bixlozone formulation (including a mixture of bixlozone CS and bixlozone SC) provides crop safety that is at least equal to, and often greater than, the level of safening that is provided by a traditional safener with non-encapsulated bixlozone (bixlozone SC). Additionally, a ZC bixlozone formulation also brings additional safety benefits to non-target plants when the non-target plants are exposed by a spray drift event by providing volatility control following application to the soil. A safener is not strictly required in compositions including both encapsulated bixlozone and non-encapsulated bixlozone. Compositions including both encapsulated bixlozone and non-encapsulated bixlozone in a ZC formulation are effective and may be used in a variety of forms. Enhanced target crop safety may also be achieved by adding a safener to a bixlozone ZC formulation. In these modified bixlozone ZC formulations, the bixlozone ZC formulation itself provides the majority of the safening effect. In one embodiment, the present disclosure is directed to a composition comprising: (i) encapsulated bixlozone; (ii) non-encapsulated bixlozone; and (iii) optionally an additional active ingredient, wherein the composition does not comprise a safener. In another embodiment, the present disclosure is directed to a method of preparing a composition, the method comprising: I) encapsulating bixlozone; and II) forming a mixture comprising: (i) the encapsulated bixlozone; (ii) non-encapsulated bixlozone; and iii) optionally an additional active ingredient, wherein the composition does not comprise a safener. In yet another embodiment, the present disclosure is directed to a method for controlling undesirable vegetation, the method comprising applying to the undesirable vegetation or to a locus thereof or applying to a soil or crop to prevent an emergence or growth of the undesirable vegetation a composition comprising: (i) encapsulated bixlozone; (ii) non-encapsulated bixlozone; and (iii) optionally an additional active ingredient, wherein the composition does not comprise a safener.
