If you look at the spraying methods of vineyards demonstrated in the header image and the video, you can see that something is wrong.
The amount of the pesticide/fertilizer that just flies away and never reaches the targeted plant is enormous. It often goes and sprays the neighbours "eco vineyard" which surprisingly, resists all diseases "without spraying" :) Not only that it pollutes the environment, but it's also a waste of sometimes really expensive spraying material.
The best spraying methods I found are presented in the videos here and here.
How could we spray the tree-form plants and lower the environmental pollution and at the same time save the material = reduce the costs?
Assumption is that people need to spray the vineyards and fruit because the sorts are non-resistant to common diseases and environmental factors. Please, avoid suggestions like "don't spray them".
