The same four crops that have been modified for herbicide resistance have also been modified for insect resistance using the Bt toxin. However, the downside of herbicide use on GM crops is that when agriculturalists use the same pest management tactic for years, they start to see pests (such as weeds) that are resistant. However, weed populations resistant to each of these modes of action already exist in North America. apps digital turbine news. Because herbicides tend to affect plants more quickly and severely than animals, the most useful biological sign of herbicides is effects on aquatic plants (Kreutzweiser et al. .
