Pyrazosulfuron-ethyl( code name NC-311, trade name SiriusTM ) is a new sulfonylurea herbicide for rice, being developed and launched in major rice producing countries.

In greenhouse studies, NC-311 demonstrated excellent herbicidal activity with both pre and post emergence applications. I75 values of NC-311 pre-emergence were below 10 g a. i./ha except for Echinochloa crus-galli. However, E. colona was much more sensitive. Selectivity of NC-311 between rice seedlings and Cyperus serotinus was sufficient, while that between rice seedling and E. crus-galli was marginal in water culture study.

In field study, however, NC-311 alone demonstrated a good control of E. crus-galli in China and other countries. It is necessary for NC-311 to be combined with grass herbicides in dry seeded rice or in countries where they require higher performance and a wider application window.
