>Beekeepers were refusing to take their bees into those orchards? This idea was stunning to me. What would happen if beekeepers in the United States and other places in the world simply insisted that farmers shifted their practices?

Actually some of us have. I will only pollinate organic orchards and then only with a signed agreement on spraying while my bees are there. I have also raised prices on pollination since I've found the honey produced by non-pollinating hives is larger than the pollination hives. I lost several hives in one orchard and the remaining hives never recovered and died in the winter.
