Nitrofen solution is primarily used as a herbicide in agricultural practices to control a wide range of weeds in crops such as rice, soybeans, and vegetables. It works by inhibiting photosynthesis in plants, effectively preventing weed growth and ensuring better crop yields. Additionally, it has been utilized in research settings to study its effects on plant physiology and environmental impact. However, due to its potential toxicity and environmental concerns, its use has been restricted or banned in many regions, prompting the development of safer alternatives for weed management.
