The main difference between how Spectracide and Roundup work is that Roundup successfully kills the entire weed including roots while Spectracide, on the other hand, only kills the part of the weed that it touches. Spectracide may be safer than Roundup and it does not persist in soil or water.

Glyphosate is suspected of causing genetic damage. Glyphosate is acutely toxic to fish and birds and can kill beneficial insects and soil organisms that maintain ecological balance. Laboratory studies have identified adverse effects of glyphosate-containing products in all standard categories of toxicological testing.
Is Glyphosate Banned in the United States? Despite the IARC report's 2015 conclusion that glyphosate is a probable human carcinogen, the U.S. Environmental Protection Agency (EPA) has held that glyphosate poses no unreasonable risk to the environment or human health.
