What is the chemical name of cell membrane disruptors?

The chemical name of cell membrane disruptors refers to a class of herbicides that target and disrupt the integrity of plant cell membranes. Bipyridylium compounds, which include substances like paraquat and diquat, are well-known examples of this class. They function by generating reactive oxygen species that lead to oxidative damage within plant cells, ultimately causing cell lysis and death.

In contrast, the other options do not represent cell membrane disruptors. Atrazine is a photosynthesis inhibitor, propylene is used primarily as a carrier or an ingredient in other formulations, and dicamba acts as a growth regulator rather than directly disrupting cell membranes. Therefore, bipyridylium compounds are distinctly categorized for their active role in breaking down cellular structures, making them the correct answer in this context.
