Propaquizafop is a selective herbicide commonly used to control grassy weeds in rice paddies and other crops such as wheat, barley, and oats. It belongs to the aryloxyphenoxypropionate herbicide group and works by inhibiting the enzyme acetyl-coenzyme A carboxylase (ACCase), which is essential for fatty acid synthesis in susceptible grass weeds.
Propaquizafop is valued for its efficacy, low application rates, and selective action against grassy weeds while being relatively safe for broadleaf crops. However, it requires careful application to avoid damage to desirable vegetation, and proper stewardship practices are essential to minimize the risk of resistance development and environmental impact.
