I have seen only in news TV, but not real in agriculture, but heard a lot. Why don't you post some photos or videos in these thread so people can understand it. Drones can easily kill dangeros insects and automate in spraying pesticides where it necessary.
I am hoping to see your products here soon since it is a mandatory to get from good manufacturer than reseller. I have lost some of monies to locall sellers where they sell almost duplicate ones and some were original which stayed long last. I mean other Irrigation products not drones.
