The conventional catastrophic injury symptoms normally associated with short-term herbicide use in diagnosing herbicide damage will be covered. In addition, the long-term role of certain pre and post-emergence herbicides in chronic disorders—including disrupted acclimation, reduced hardiness, reduced nutrient uptake, and weakened tissue integrity—following repeated use near or on woody landscape plants, will also be presented.
