Recommended	AGRAL 90 Non-ionic Liquid Wetting & Spreading Agent If weeds are beyond the 2-leaf stage, then add a spray surfactant. Use a non-ionic surfactant (e.g., AGRAL 90 Non-ionic Liquid Wetting & Spreading Agent) at 0.20% v/v.	0.20% v/v
Recommended	AGRAL 90 Non-ionic Liquid Wetting & Spreading Agent If weeds are emerged at the time of MST 4 SC Herbicide application, the addition of a non-ionic surfactant (e.g., AGRAL 90 Non-ionic Liquid Wetting & Spreading Agent) at the rate of 0.2% v/v is recommended. If weeds have not emerged, no adjuvant is recommended.	0.2% v/v
