The airplane struck a berm during a forced landing resulting in substantial damage. The pilot reported he was finishing spraying a field when he "encountered an unscheduled power rollback." He executed a forced landing to an alfalfa field. During the landing roll the airplane impacted a berm and sustained substantial damage. The inspection of the airplane's fuel system revealed the fuel strainer was blocked with a black rubber like substance. The fuel truck that fueled the airplane was checked for contaminates.
