spiromesifen (Oberon 4SC)

Oberon 4SC works via contact activity. It is translaminar, but not widely systemic. Good coverage is important. Use a spray adjuvant. Apply Oberon 4SC at 4 to 8 fl. oz/A via ground or air, using enough water to obtain thorough coverage. Chemigate at 100% travel speed, or use only 0.1 to 0.15-inch water, with Oberon 4SC at 8 fl. oz/A. If needed, a repeat application can be made 7 days or more after the first application. Don’t apply after Movento (another Group 23) unless another insecticide is used first.
