Farmers returning to manual methods of weed control as herbicide resistance spreads

As reported in the Wall Street Journal yesterday, farmers are observing a dramatic increase in herbicide-resistant weeds and are being forced into applying larger quantities and a wider range of herbicidal chemicals. These decisions come with both economic and environmental costs and are forcing some farmers to spend $150/acre to weed their fields by hand. However, the efficiency of hand weeding can be dramatically increased though drone-collected imagery that allows the immediate identification and isolation of problem areas. Agribotix drones have already been used to identify troublesome areas and allow the grower to focus only on areas in need.
