What Happens when Roundup ReadyTM Cotton is Sprayed with Roundup® after the Four Leaf Stage?

S.G. Matthews, P. Brawley, T.C. Mueller and R.M. Hayes


 
ABSTRACT

Roundup ReadyTM cotton is resistant to vegetative injury from Roundup® (glyphosate) herbicide, but subtle effects on reproductive (fruiting) development may occur if Roundup® is applied beyond the 4-leaf stage. Experiments were conducted at Jackson, TN during 1995 and 1996 to determine the effect of Roundup® applied overtop of Roundup ReadyTM cotton. In 1995, Roundup® was applied at 3 pints (1.12 lb ae) per acre to Coker 312 RR, Paymaster lines PM 1215RR, PM 1220RR, PM 1244RR, PM 1330RR and PM 1380RR cultivars at the 4-, 5-, and 7-leaf stage.
