By Betty on 06/01/2017

Expert response:
Thank you for your review. I apologize that the label is extensive and confusing. We recommend using a surfactant like Non-Ionic Surfactant to help increase the efficacy of this product. If you use the surfactant, the recommended mixing rate for one gallon would be 2 tsp of surfactant with approximately .4 oz of the Grass out per gallon of water per 1,000 sq feet. Please let us know if you have any other questions.

QI have a one acre plot of Ladino clover and sweet clover for My Bee's I want to kill the fesque in th plot ,
without harming My Bee's
AThe Grass Out Max is labeled for controlling Tall Fescue and would be safe sprayed over the top of broadleaf plants such as clover. While the product is not an insecticide, it would be recommended to avoid spraying when bees are active or foraging, such as very early in the morning or very late at night. We would also recommend not applying when clover is in bloom as this is when they would be most active.
