Peter Jentsch, entomologist at the Hudson Valley Lab, sent me some
web info on Yamaha drones used for spraying rice in Japan (see
http://www.youtube.com/watch?v=ds1BeKsZSho&feature=related and
http://www.barnardmicrosystems.com/L4E_rmax.htm). Another website
indicated that these drones were already being used to spray 600,000
hectares of rice in Japan in 2005 (the last year included on that
graph).
