Heavy use of glyphosate over the last few decades has created an emergence of glyphosate-resistant “super weeds,” of which roughly two dozen species have been discovered. These weeds are likely responsible for farmers, agricultural workers and others spraying more and more glyphosate, according to Science in Society.
Cristiano Peano, an associate professor of General Arboriculture and Arboreal Crops at Turin University and a consultant at Slow Food, recently spoke about how glyphosate use is harming soil.
The safety of Roundup and its key ingredient, however, have become controversial to say the least. Dozens of studies have correlated exposure to glyphosate to a number of different health issues, including ADHD, Alzheimer’s disease, autism, birth defects, cancer, Celiac disease, colitis, heart disease, inflammatory bowel disorder, kidney disease, liver disease, non-Hodgkin lymphoma and Parkinson’s disease, among others.

Alternatives-some people use vinegar or similar acids, others use boiling water, and here's a novel idea, pulling out the weeds and composting them-making them work for you. Another way is a flame weeder using gas, simple and easy to use in larger areas. We have one, love it, but you can't beat hands on management.
