The ability of weeds to grow, establish, and adapt are examined through the lens of ecological principles and plant physiology. Opportunities and limitations of weed management practices are analyzed across chemical, physical, cultural, and biological tactics. Includes the development of practical skills for weed identification, determining herbicide symptomology, and interpreting application and mixing instructions on herbicide labels. ### requirements
