Ratna Pyro is a premium, systemic, pre-emergence herbicide containing Pyrazosulfuron Ethyl 10% WP. It belongs to the Sulfonylurea group and acts as a highly effective selective herbicide for paddy. By inhibiting the Acetolactate Synthase (ALS) enzyme, it halts cell division in weeds, preventing the growth of aggressive sedges and broadleaf competitors from the root up. It is renowned for its low application rate, excellent crop safety, and long-lasting residual control, ensuring a weed-free start for high-yield rice cultivation.
