There are two different subjects relative to SNG’s wheat post,imho. 1) is roundup herbicide 2) is GMO.
Wheat is grown shoulder to shoulder within the farmers field boundary. There is no need to spray roundup as the weeds are naturally shaded out. The wheat naturally dries out prior to harvest and to truck spray it would be expensive and yield no benefit at all. Plus, unless you aerilly spray it you would destroy much of the crop by driving over it. Using round up on wheat is a myth.
2) There is no commercially available GMO wheat at the present time.
3) The controversy over the subject of modern wheat really has nothing to do with either roundup or gmo. Rather it has to do with modern hybridization.
