I thought I should pass this bit of info along to all who plant RR Soy Beans. A friend of mine planted the Eagle Brand of RR Soy beans. He sprayed them after they were about a foot tall with Roundup Pro. A week later he returned to see his entire plot brown and dead!! I on the other hand sprayed with a generic Gly-Pho on my beans and nothing happened to mine. I have found out that ROUNDUP PRO will kill RR soy beans as it contains Diquat an additive to help kill weeds, but it will also kill RR Soy Beans. So, be sure the product you spray on your RR soys only contains Gly-Phos product. Hope this helps.
