In which year was resistance in American black nightshade first reported?

• A. 1985
• B. 1996
• C. 2001
• D. 2002

Answer: (A)

Resistance in American black nightshade was first reported in 1985. This date marks a significant point in the study of herbicide resistance, particularly with respect to this weed species. The emergence of resistance signals that certain weeds can survive applications of herbicides that were previously effective, leading to increased challenges in weed management. Understanding the timeline of when resistance was first documented helps agricultural professionals and weed scientists to appreciate the evolution of weed management practices and the importance of rotating herbicides and utilizing integrated pest management strategies to mitigate further resistance development.
