Patent ID: 8129564

Claim:
A method for selectively controlling weeds in a field containing a crop of transgenic glyphosate-tolerant cotton plants having increased glyphosate tolerance in vegetative and reproductive tissues, the method comprising: when at least five leaf nodes are present on a cotton plant of said crop, applying to foliage of said crop and weeds a sufficient amount of a herbicidal glyphosate formulation comprising N-(phosphonomethyl)glycine or an agronomically acceptable salt thereof to control growth of said weeds without incurring significant glyphosate-mediated reproductive injury to said plant of said crop; and controlling the concentration of N-(phosphonomethyl)iminodiacetic acid and salts thereof present in the herbicidal glyphosate formulation and the application rate of the herbicidal glyphosate formulation to said crop and weeds in said field such that the application rate of N-(phosphonomethyl)iminodiacetic acid and salts thereof is no more than about 2.5 g of N-(phosphonomethyl)iminodiacetic acid equivalent/hectare so as to not induce significant leaf necrosis in said cotton plants of said crop.
