Management measures for the mitigation of spray drift of very fine droplets sprayed by a spraying robot. [PDF]

Sci Rep
Pesticide spraying is one of the most significant processes in agricultural production and one of the most complicated, risky agricultural operations. Side effects of pesticides can cause acute poisoning and serious chronic diseases in humans. Robotic spraying in agriculture is one solution to avoid human intervention.
