While it's an impressive piece of technology, I think it's the wrong way to approach this problem. Of course big scale agriculture needs to spray glyphosate and the like, but a technology to minimize the usage combined with a more customized method of application should be considered, too. Hops farmers in Germany e.g. only apply insecticides to the roots of a plant to protect them from being eaten up. If the farmers add some bee hives to the mix, it might help to recover the bee population, which is better than giving up on bees and replace them.
