To me, this seemed very much like imposing a regulation of "not many naked lights" in the presence of inflammable gases.
Even if Guy Charter were able to persuade his bees to refrain from cross- pollinating GM and non-GM crops, can we really believe that wind pollination only takes place over a few yards?
In practice, most pollen will only travel a very short distance, but the occasional wind eddy is bound to lift some pollen clear of the ground, from where it may travel on the winds for any distance: after all, sand from the Sahara occasionally causes coloured rain in England. It seems that the regulations are only intended to reduce cross-pollination to the level where it does not interfere with the trials themselves. They do not, and cannot, prevent escape of GM genetic material into the wild.
