Except for the time it hung around 141 days in Iowa. Or over 2 years in a Swedish forest. Even 2,4-D tested side by side dissipated faster. And let's not forget Monsanto got sued and lost a false advertising suit stating Roundup was biodegradable. And left clean soil. Oops. Or the EU stated gly was dangerous for the environment and toxic for aquatic organisms. You leave the US corporate proganda machine things are much different. And when a major corporation like Monsanto loses a false advertising suit, how can people still sit there and say, it leaves the soil clean? Quickly?
