In particular, farmers in the Mississippi Portal encountered serious and unexpected problems with their herbicide-tolerant cotton during the 1997 growing season (Virginia Cooperative Extension). Some growers found deformed bolls and bolls that dropped off the plants. About 20 percent of the region’s herbicide-tolerant cotton was affected. However, the problems may have been caused by factors other than the herbicide-tolerant technology itself, such as soil type and weather conditions.
