How do many herbicides inhibit weed growth?

Many herbicides inhibit weed growth by targeting specific biochemical pathways or processes essential for plant development. For example, some herbicides disrupt photosynthesis, while others interfere with amino acid synthesis or hormone regulation, leading to stunted growth or plant death. Additionally, certain herbicides mimic natural plant hormones, causing uncontrolled growth or other harmful effects. By selectively affecting weeds while minimizing impact on desired crops, these chemicals help manage unwanted vegetation.
