I am concerned about GMO's more than RU. I have no chemical engineering background to make the assertion that perhaps some of the honey bee demise is a result of GMO's. I see the relationship in mass food production of making plants resistant to RU, ergo GMO.
But what have we lost in that relationship? GMO corn, soy beans, et al, are still pollenated in the same manner. Do we know ON A CELLULAR LEVEL if the pollen and nectar of GMO flowers are equivalent to the non-modified varieties? Do GMO's have an adverse effect on bees? If we lose bees - we're done.
RU to GMO to bees...the demise of the OP. Oh well...carry on.
