There is a huge difference between natural chemicals and synthetic chemicals. Indeed, herbicides like atrazine are absolutely polluting all the ground water. Scott's Weed and Feed sells it in their bags. It's an oxymoron. It's a big money making machine. It's the big fat lie.
Synthetic is nothing, not even close to what you find in nature. Nature does not have catalysts, synergists and the like.
So, wholesale condemnation will continue in the organic community. Why? Because we know better, are usually better read than people who use synthetic practices and the greatest of them all is WE DON'T BELIEVE THE BIG LIE.
I'm getting awfully bloody tired of the wholesale condemnation of
