Sprayers with lasers

The Ohio State University, College of Agriculture and Environmental Science has develop a new sprayer that would save costs on chemicals and harm on plants. This new prototype is an "intelligent" sprayer system that uses a combination of lasers and computer algorithms to monitor specific field conditions and only apply the amount of chemical needed for each plant. Studies have shown that this new system can reduce the amount of chemicals used by 40% to 87% with a better spray strategy control. For now the prototype is specifically for orchards. Eventually they plan on adapting this technology into other crops. The main reason for this new technology creation was for savings in the industry. Reports say that farmers spend more than $4 billion in pesticide each year.
