Abstract
Methods of reducing injury to crop foliage and achieving weed control using encapsulated acetamide herbicides in pre-plant or preemergence crop plant applications are described. A composition comprising a first population of a particulate microencapsulated acetamide herbicide and a second population of a particulate microencapsulated acetamide herbicide is described wherein the application mixture exhibits a bimodal acetamide release profile. The compositions provide reduced crop injury through controlled herbicide release.
