Title: Fall Preplant Trifluralin (Treflan) Applications in Wheat
Author: Miller, S. D.; Nalewaja, J. D.
Description: Green and yellow foxtail grass were important weeds in North Dakota wheat fields. Trifluralin had proven to be an effective herbicide for control of foxtail in under normal environmental conditions. Spring application of this herbicide had to be administered during a busy period. The shallow incorporation after seeding left a loose soil surface that was susceptible to wind erosion. Having the advantage of Fall apllication would be advantageous as farmers would have a longer period for treatment and Fall incorporation would reduce the potential for soil erosion as compared to Spring post-seeding. the objectives of the research covered in this article were to determine weed control and wheat tolerance to Fall applied trifluralin as influenced by formulation, soil incorporation, wheat seeding depth and combinations with triallate. The results of the study indicated that the Fall application of trifluralin gave good foxtail control for the following season. The best application requirements are presented at the close of this article.
