Genetically engineered glyphosate-tolerant soybeans. Roundup is the trade name for glyphosate, a broad-spectrum herbicide. Farmers planting RR soybeans pay more for the seed, must use certain herbicide application practices, and may not save and use their own seed as part of a pesticide resistance management plan. The benefits include a reduction in the number of herbicide applications, with potential savings in both chemical and labor costs.
