Bug-dropping drones are being used on some crops in Australia.
A University of Queensland student has come up with a way for drones to put the beneficial “californicus mite” onto crops from the air, using a special container to hold them and a spreader. The good bugs eat the crop harming bugs, which include other types of mites.
Reports say the bug dropping has been tried successfully on corn crops, and there are plans to do that on other crops.
