Theres a trade off though, less GMO's equals more pesticides and herbicides unless you go full organic.
Since planting roundup ready beans, BT corn and going to 100% no-till on all our acres our chemical use has steadily gone down.
Organic has it's uses as well, as we've been planting cover crops so there is always something green growing which helps reduce weed pressure,reduces runoff and reduces burndown herbicide rates in the spring, unfortunately a lot of the world can't afford it. While on occasion organic yields can and do exceed conventional yields, the average though is less than half of conventional.
Some of these new GMO's are pointless and is just Monsanto trying to corner more of the market. I've been exposed to haymaking in one form or another for 40 years and don't see any point in roundup ready alfalfa. Herbicides already exist for use with alfalfa anyways, and if done properly none are needed anyways. Start with a clean seedbed, plant correctly with a cover crop to keep any weeds at bay and mow often before any weeds can goto seed, no weed problem then.
