Walmart could soon deploy drones to help farmers

Walmart Inc's patent filings hint that it may see a future where farmers use its drones to not only spot crop problems but selectively apply chemicals or even disperse pollen to bring shoppers the freshest and cheapest food possible. The world's largest retailer applied for six patents last year on drones that aim to prevent damage to crops, control pest attacks on farms and cross-pollinate plants, according to U.S. Patents and Trademark Office documents that were made public last week and seen by Reuters. Groceries make up 56 percent of the company's total revenue and Walmart may see drone technology as one way to get food from farms to store shelves faster and more cheaply to compete with Amazon.com Walmart Inc's patent filings hint that it may see a future where farmers use its drones to not only spot crop problems but selectively apply chemicals or even disperse pollen to bring shoppers the freshest and cheapest food possible. In one application, Walmart seeks to patent a system that would use drones to identify crop-damaging pests and then dispense insecticides on the critters.
