Pigweed Infestation

297

Situation:

Growers can use TerrAvion imagery to identify weed issues in their fields, make targeted herbicide applications, and evaluate the effectiveness of herbicide treatments. In this example, the grower noticed high vigor areas in his field in the July 5 imagery, which in-field scouting revealed to be weed pressure. He used the imagery guide a targeted herbicide application, only applying herbicide in the infested areas. The 9/12/17 imagery shows the the herbicide application was successful in killing the weeds, allowing for more uniform

growth throughout the field.

Action:

Use TerrAvion imagery to identify suspicious high vigor zones in early-season imagery, which may correspond to weed pressure. Use imagery to guide targeted herbicide applications and evaluate treatment effectiveness.
