Agriculture robots to help you on spraying

If we want sustainability, do we want spraying robots?  

Just a few words on the combination of agriculture robots that perform spraying and the road to sustainable farming. Ecological farmers perform spraying on several crops with biologically composed products. What that in mind, there is enough reason to encourage the development of agriculture robots to do spraying activities with a sustainable vision. 

But of course, there is flipside: The robots are likely to make spraying on conventional farms also more efficient. And even if there are robots that reduce the application of chemicals with 90%, due to targeted application with the use of camera's .... it is still 10% more than zero.
