Application Notes

Surmise Pro is a foliar-active herbicide and works best when weeds are actively growing. Thorough spray coverage is important for consistent control. Weed control may be reduced when applications are made to weeds under drought stress, cool temperatures, or dense growth conditions.

For spot or directed applications, use 1 to 2 fl. oz. per gallon of water depending on weed size and growth stage. For broadcast applications, apply 32 to 80 fl. oz. per acre in a minimum of 40 gallons of water per acre. Surmise Pro is rainfast in as little as 30 minutes and up to 4 hours depending on environmental conditions, weed species, and application rate.

No surfactant is required when applying this product. Ammonium sulfate may improve weed control where hard water is a concern. Do not apply by air, through irrigation systems, or allow grazing of treated vegetation.

Not for me
This in combination with the aloe-ph balancing face wash was not a good fit for my skin. It had me break out with cystic acne. I went back to Hydro Boost and it cleared up in a week. But that’s for my skin. Also, I didn’t care for the consistency of the product.

A game-changer for oily and combo skin!
Okay, I did not expect to love this toner as much as I do but wow, it completely changed my skin game! The jelly texture feels super luxe and refreshing, and it instantly calms my skin while keeping oil under control all day. My pores look smoother, my skin feels hydrated but not greasy, and it gives that fresh, healthy glow we all want. I’ve been using it morning and night and my complexion has never looked more even. If you have combo or oily skin, this one’s a total gem.
