Synergistic herbicide agent and method for fighting undesirable vegetation.

摘要

Synergistic herbicide agent, containing an active substance, typical supporting agents and a carrier allowed for agricultural use, characterised in that it contains herbicidally effective joint amount of dimetenamid and another herbicide chosen from the group of sulphonylurea herbicides, including rimsulfuron, metsulfuron, methylo-metsulfuron, nicosulfuron, triasulfuron, primisulfuron, bensulfuron, chlorimuron, ethylochlorimuron, chlorsulfuron, sulfometuron,, tifensulfuron, tribenuron, etametsulfuron, klopyrasulfuron, pyrazasulfuron, prosulfuron and halosulfuron and a herbice from urea group, including diuron, fluometruon, linuron, tebutiuron, tidiazuron, forchlorfenuron, whereby the ratio of the urea herbicide to dimetanamid is 2:1 to 1:4 and the weight ratio of dimetenamid to sulphonylurea herbicide is 0.6:1 to 3000:1 and active substances are present at the amount of 0.01-90 weight percent. 4. Method for fighting undesirable vegetation, characterised in that synergistic herbicide is applied where undesirable vegetation grows, characterised in that it contains herbicidally effective joint amount of dimetenamid, herbicide chosen from from the group of sulphonylurea herbicides, including rimsulfuron, metsulfuron, methylo-metsulfuron, nicosulfuron, triasulfuron, primisulfuron, bensulfuron, chlorimuron, ethylochlorimuron, chlorsulfuron, sulfometuron,, tifesulfuron, tribenuron, etamesulfuron, klopyrasulfuron, pyrazasulfuron, prosulfuron and halosulfuron and a herbiced from.. group, including diuron, fluometruon, linuron, tebutiuron, tidiazuron, forchlorfenuron, whereby the ratio of the urea herbicide to dimetanamid is 2:1 to 1:4 and the weight ratio of dimetenamid to sulphonylurea herbicide is 0.6:1 to 3000:1 and active substances are present at the amount of 0.01-90 weight percent, whereby dimetenamid present in the agent is used in the amount of 0.1-3 kg/hectare and sulphonylurea herbicide present in the agent is used in the amount of 1-150g/hectare and urea present in the agent is used in the amount of 0.5-600g/hectare.
