agricultural sulfur and copper usage are through the roof in 2010. The organic industry is a tiny fraction of actual food production, say 5%. Could you imagine the amount of copper and sulfur (bourdeau mix) we would need to satisfy 100% organic production for a problem like powdery mildew. Using 1 oz of 2,4-D to treat 1000 sq ft of lawn compared to 28 oz of fiesta for the same 1000 sq foot lawn, doesn't seem like reducing our pesticide usage loads to me. Especially when you have to reapply fiesta 5-8 times a year for suppression only. Why are we trying to provide a working model of plant and soil health with lawns, why not start in the farmers field or sod farm? I know why.
