AI enables low-cost tracking of invasive johnsongrass
To manage johnsongrass, a noxious weed that crowds out cotton and sickens horses, farmers have tried herbicides, burning and hand-pulling. Now, researchers in the UC Davis Department of Plant Sciences have developed a more high-tech weapon against the invasive weed: artificial intelligence and machine learning.
Using photos from Google's Street View database, the researchers have tracked down more than 2,000 cases of johnsongrass in the Western United States for a fraction of the cost and time that it would take for drive-by or other in-person surveys. They call their tool Google Weed View.
The advancement could...
