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...

Johnsongrass in organics: Mow it?
Yes, mow it! Mowing works to at least prevent seed spread and regular mowing will weaken rhizomes.
Seed establishment has the greatest potential for the establishment and spread of johnsongrass and must be prevented. Therefore, mowing works to at least prevent seed spread. An individual plant can produce 28,000-30,000 seeds and a single inflorescence can measure 1,240 seeds...

Johnsongrass? There's an app for that!
JohnsonGrass-JG (Android) and JG-JohnsoGrass (Apple) are apps for your tablet or smartphone that provided useful information about the biology, identification and management of Johnsongrass [Sorghum halepense]. It also contains a “Record” feature that allows the user to help map the distribution of the weed and its spread over time and space.
An important, noxious weed
Johnsongrass is considered a top 10...
