It is also cheaper to spray Grazon than to brush hog the fields. Dave Dave. Others, like beans, tomatoes and eggplant are very sensitive. Under the right circumstances, however, herbicide carryover can occur in any type of soil. My hibiscus plants are showing this exact same symptom, but they have never had ANY manure or pesticides, so I have no idea what is causing it, since it cannot be from Grazon. Found out grazon was used where she pastures her horses. Soil composition affects herbicidal activity and persistence through soil-herbicide binding (adsorption), leaching, and vapor loss (volatilization). However, avoid applying two or more herbicides with a longer residual life during the same season. An old guy told me it was timing. Usually, a warm, well-aerated, fertile soil with a near-neutral pH is most favorable for microbial growth and, hence, for herbicide breakdown.

Activated charcoal dust would be really good. It doesnt cost you a penny and it helps pay for my hosting! Thank you! The length of time a herbicide remains active in soil is called "soil persistence," or "soil residual life" (Figure 1).

This is an interesting post.
