Rene from Atlanta, Ga writes,

Can I mix Pramitol & RoundUp Pro?

Pramitol says to apply before weeds emerge or within 3 months. I have some weeds that have been growing most of the winter & have not died off because the winter hasn't been cold enough. Can I mix Pramitol & RoundUp Pro to kill all existing weeds & prevent new ones?


Yes you can absolutely mix RoundUp and Pramitol to apply at the same time. Keep in mind, Pramitol is not just a pre-emergent but also a post emergent product. Normally customers who do not see burn down or kill of existing weeds, or long term prevention of new ones are due to 1 of two factors. Either not enough water was used intially during application to allow proper absorbtion and penetration into the soil to create a solid barrier, or the application was done after the weeds/grasses you are trying to kill had already begun to go dormant. Even if they havent died out over the winter, they are still in a dormant faze so they are not going to suck up the product or really anything for that matter to be affected by it. Same thing will apply with the RoundUP as well. In order for it to work the weeds must be in an actively growing state with steady soil (not air) temperatures of 65 degrees or higher for at least a week straight.
