Roundup controls virtually every economically significant weed in the world. The translocating action of Roundup (right down to the roots) makes it ideal for control of an extensive range of unwanted grasses, broadleaf weeds, brush weeds, woody weeds and unwanted trees. Roundup has no harmful effect on the environment. It binds tightly to soil and can be applied safely over root zones of trees. It is broken down into naturally occurring compounds (like carbon dioxide) by microorganisms in the soil. Roundup has very low toxicity to humans and animals. It's designed to stop certain amino acids unique to plants (essential for plant growth) from forming. Roundup presents minimal hazard to spray operators. Convenient ready mixed weedkiller. First effects seen in 48 hours. Covers an area of up to 140m2. Roundup ready to use doesn't poison the soil.
