Materials are not listed in order of preference or efficacy. This listing implies no endorsement on the part of Oregon State University Extension. We are investigating the efficacy of soil drenches of the over wintering stages of the midge. Initial results look promising. Pod gall midge is native to the east coast of North America where populations of the pest are generally maintained below an economic threshold by a complex of natural enemies.
Research investigating biological control of the midge is ongoing.
