Developer's Description

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.
