Distinguishing herbicide injury from other causes of abnormalities on landscape plants can be challenging. The Field Guide to Herbicide Injury on Landscape Plants presents more than 200 color photographs of several herbicide families, with images of vegetables, annuals, and herbaceous and woody perennials. Diseases and environmental conditions that may show similar symptoms are also highlighted in the key.
This 112-page, color-coded field guide can make your diagnosis more accurate and efficient.
