Agricultural biotechnologies apply modern knowledge in molecular and cell biology to produce new varieties and similar genetic materials. The use of genetically modified (GM) crop varieties has grown dramatically since they were introduced in 1995, and large portions of the land allocated to corn, soybeans, and cotton are grown with these varieties. The evidence from the United States, Canada, China, India, Brazil, and Argentina suggests that these applications of biotechnology in agriculture increase yield, reduce the use of pesticides, and save production costs. .
