Could giant drones and robotic vehicles prevent chemical spray drift?

Giant drones and robotic sprayers might sound like something from an alien world.

But the new technology that has the ability to precisely spray weeds is being seen as the key to reducing the risk of chemical spray drifting onto neighbouring properties and paddocks full of crops.

The issue of spray drift is an ongoing issue for farmers with incidents resulting in crops being damaged and millions of dollars of potential income being lost.
