Interpretive Summary: For crop producers, weeds represent the most complex and expensive pest management challenge that must be addressed on an annual basis. Weeds frequently reduce crop yields by 20 to 50% by their competition for water, nutrients, and sunlight. Weed control is complicated because there are many weeds with different life cycles and various strategies for competing successfully with desirable crops in selected niches. Herbicide resistance also plays a significant role in producer's decisions regarding weed control options. The Clearfield* system enables producers to more effectively manage troublesome grass weeds like jointed goatgrass and feral rye. Finally, each producer must evaluate the economics and efficacy of the various weed control options in order to make the best choice for his farming operation.
