The list of resistant and hard-to-control weeds has grown substantially during the past decade — resulting in an evolving landscape of increasingly challenging weeds. According to the National Invasive Species Information Center, it is estimated that, throughout the world, more time is spent removing weeds and invasive plants from farm fields than any other farming activity and that weeds currently reduce worldwide crop yields by more than 10 percent annually.

Advancing Agriculture Through Science

At a time when feeding a growing population in a sustainable manner is a greater challenge than ever before, production losses to weeds are unacceptable. Growers are searching for solutions which will maintain the current efficient and environmentally conscious production practices.

Herbicide-tolerant crops are currently adopted on 93 percent of soybean, 80 percent of cotton and 73 percent of corn acres in the United States, with adoption continuing to grow internationally in other countries, such as Brazil and Argentina. Growers have invested substantially in this cropping system because it allows them to reduce labor needs while increasing the productivity and efficiency of their operations. The current herbicide-tolerant production system also allows increased use of conservation tillage practices with the associated environmental benefits.

However, the long-term effectiveness of this system is threatened by increasingly hard-to-control and resistant weeds. For farmers to meet the increasing global food demands in a sustainable manner, they must have solutions which allow them to continue to improve productivity. Without supplementing the current herbicide-tolerant cropping system with technological advancements, growers risk losing effectiveness and vital economic and environmental benefits.
