A kind of synergistic herbicidal compositions

What the present invention relates to is a kind of synergistic herbicidal compositions, and said composition contains herbicidal active component pyribenzoxim and methoxone or derivatives thereof, is applicable to the weeds in selectivity control useful crop plants such as rice.Synergistic herbicidal compositions, comprise herbicidal active ingredient pyribenzoxim and methoxone or derivatives thereof, wherein the weight proportion of pyribenzoxim and methoxone or derivatives thereof is 100:1 to 1:100.The present invention also can contain safener.The present invention, by pyribenzoxim and methoxone or derivatives thereof are carried out binary built, makes obtained new compositions can effectively solve the defect being used alone pyribenzoxim, expands and compose the herbicide of weeds, delay drug-fast generation simultaneously.Once use substantially can solve paddy field weed, saving of labor, save time, laborsaving, tool is increased income to increasing production of rice simultaneously and has certain effect.The control of paddy field broad leaved weed, grassy weed and sedge weed achieves gain effect.
