HERBICIDAL SUBSTITUTED PYRAZOLE COMPOUNDS

摘要

Herbicidal compositions containing substituted pyrazole compounds and derivatives thereof of formula (Ia), wherein Y is O or S and Z is a carbon-carbon single bond, O, S, C=O or C=N. Methods of controlling undesirable vegetation using these compounds and derivatives are also disclosed. Herbicidal compounds wherein Z is a carbon-carbon single bond, S, C=O or C=N are also described.
