Interpretive Summary: Producers in Ukraine are struggling to control perennial weeds in their cropland. This paper describes management systems that have been successful in controlling perennial weeds in the United States. A key aspect of management is a systematic approach, where numerous tactics are combined together. Components of successful systems include control tactics such as moving or herbicides, competitive crops, crop sequencing after one year of intensive control efforts, and a long-term program. Crucial to effective management is understanding the ecology of carbohydrate movement in perennial weeds.

Technical Abstract: Perennial weeds are prominent in croplands of Ukraine. Scientists in the United States have explored various control tactics to control perennial weeds. This paper describes the basic ecology of perennial weeds, then outlines possible management systems for three prominent perennial weeds. A key aspect of perennial weed management is understanding carbohydrate movement in the plant during the growing season. Carbohydrates ensure plant survival and growth across time whereas herbicide movement within the plant coincides with carbohydrate translocation. Effective management requires multiple tactics used jointly, and include control tactics, competitive crops, intensive control during the first year, appropriate crop sequencing, and long-term management. Producers in the United States have eliminated perennial weeds with intensive management across four or five years.
