Glufosinate Tolerant Soybean
Glufosinate Tolerant Soybeans are genetically engineered soybeans that have had their DNA modified to withstand the herbicide Glufosinate. (Glufosinate is also referred to as Phosphinothricin and it is sold under the brand names Basta and Liberty.) All glufosinate tolerant soybean varieties are sold by Bayer CropScience under the brand name "LibertyLink."
