How effective is RM43? Everything you need to know

If you are in the market for a product that can help you eliminate weeds and prevent them from growing back, without a doubt RM43 is one of the top choices for a good reason.

RM43’s main active ingredients include Glyphosate and Imazapyr; When these two are mixed with other supporting ingredients, the concentrate becomes powerful enough to destroy every vegetation they come across

Glyphosate works by inhibiting further production of enzymes required for plant growth, while Imazapyr works by stopping protein production and cell growth hence killing the plant.

How much RM43 should I add to a gallon of water?

RM43 comes as a concentrate, which has not been mixed with water. If you are using it for spot treatment, you will need to mix six ounces of the concentrate in one gallon of water.

On the other hand, if you are spraying a big chunk of land at once, you should mix 7.4 ounces of the concentrate with ten gallons of water for every 1000 square feet.
