Which herbicide is known for its rapid uptake and effectiveness against floating and submerged plants?

Diquat is recognized for its rapid uptake capabilities and its effectiveness against both floating and submerged aquatic plants. The mode of action of Diquat involves cell membrane disruption, leading to rapid plant desiccation and death. This herbicide is specifically formulated for quick action, making it particularly beneficial for managing invasive aquatic species that can quickly outcompete native flora.

When applied to water bodies, Diquat quickly penetrates the leaf tissues of the target plants, which allows it to be effective even against those plants that may have their growth submerged beneath the water's surface. This feature makes Diquat a preferred choice for managing the growth of problematic aquatic weeds that can hinder recreational activities and disrupt aquatic ecosystems.

In contrast, other herbicides listed may not share the same combination of rapid uptake and efficacy against both floating and submerged species, which is why Diquat stands out in this context.
