The invention discloses a dispersible oil suspension agent containing cyproconazole. The dispersible oil suspension agent is prepared by effective active compositions including cyproconazole and azoxystrobin and a wetting agent, a dispersant, an emulsifying agent, a thickening agent, a stabilizing agent, an anti-freezing agent, a defoaming agent and non-aqua-system dispersing media, wherein the weight proportions of the compositions include that the cyproconazole ranges from 0.5% to 10%, azoxystrobin ranges from 5% to 30%, the wetting agent ranges from 0.5% to 3%, the dispersant ranges from 0.5% to 8%, the emulsifying agent ranges from 0.5% to 10%, the thickening agent ranges from 1% to 6%, the stabilizing agent ranges from 0.5% to 20%, the anti-freezing agent ranges from 1% to 5%, the defoaming agent ranges from 0.1% to 2% and the rest are the non-aqua-system dispersing media. The two active compositions can be mixed to prepare the dispersible oil suspension agent, thereby preventiveeffect of the dispersible oil suspension agent is enhanced, effective period is prolonged, and preventive effective of the dispersible oil suspension agent is obviously better than other agents prepared by the active compositions. Besides, the dispersible oil suspension agent is safe to crop and environment, application dose of agents is reduced, cost is saved, and the dispersible oil suspension agent meets the safety requirement of agrochemicals.
