Abstract

Wild cats is problem in the small grain areas because it has certain characteristics which allow it to survive and infest the soil. It is an ecological equivalent to the crops with which it grows. It sheds its seed as they ripen and all seeds do not ripen at the same time. The seeds are dormant at the time they are shed and remain so for varying lengths of time; they may also go into secondary dormancy. Any effective control must encourage germination and destruction of plants before seed production. Wild oats rates as the most troublesome weed in an area which includes the northern half of South Dakota, northwestern fringe of Minnesota, most of North Dakota, Montana and the prairie provinces of Canada, Manitoba, and Alberta. With the forging in mind, this study was initiated in four parts: 1. to determine if a particular cultural practice will affect the establishment of wild oats stands, 2. To determine the effectiveness of several cropping tillage practices for eliminating wild oats, 3. To compare the effect of different types of implements at three dates, early, medium, and late for fall cultivation upon the germination of wild oats the following spring, and 4. To determine the effect of Avadex.
