JG-JohnsoGrass app for iPhone and iPad

The JG App provides useful information about the biology, identification, and management of JohnsonGrass (Sorghum halepense) which is considered as a noxious weed throughout the south, southwest, and west and is one of the ten most troublesome weeds in the world.
Using the “Record” feature of JG App, you can help us map the distribution of this weed and its spread over time and space.
The JG App was funded by USDA-AFRI and The University of California, Division of Agriculture and Natural Resources (UC ANR).
The content of the JG App are based on two UC ANR publications:
- Publication 8569, ISBN-13: 978-1-60107-978-7
- Publication 8570, ISBN-13: 978-1-60107-979-4
