Efficacy of glufosinate and weed control in transformed corn and soybean

Glufosinate is a postemergence herbicide that inhibits the glutamine synthetase enzyme in plants, causing an accumulation of ammonia, inhibition of photosynthesis, and ultimately plant death. The use of this herbicide has been limited to no-tillage prior to planting or in noncrop areas. Recent developments in gene transfer technology have produced crop plants that are tolerant to postemergence applications of glufosinate. Information on glufosinate efficacy on annual weed species is limited. The objectives of this research focused on defining use rates and application timings of glufosinate for effective weed control, evaluating weed control programs in tolerant corn and soybean, and characterizing foliar absorption and translocation of glufosinate as possible physiological mechanisms for plant tolerance.
