The compound suspension agent at least includes 15 parts of diafenthiuron, 10 parts of tolfenpyrad, 3 parts of fatty alcohol polyoxyethylene ether, 3 parts of styryl phenol polyoxyethylene ether, 0.3 parts of xanthan gum, 0.4 parts of sodium benzoate, and 0.3 parts of a defoamer, wherein deionized water is added to 100 parts in total. The raw materials are all pumped into a preparation kettle and are mixed and stirred to form a mixture. The mixture is then subjected to primary grinding through a colloid mill and is finely ground in a sand mill. Sample analysis is then carried out, and if qualified, the mixture is filtered, metered and packaged and is stored in a storeroom. In a compound suspension agent being 25 mass%, the diafenthiuron and the tolfenpyrad are blended according to the ratio of 1.5:1, and at this ratio, a significant synergistic effect range can be achieved, while compound suspension agents in other blending ratios cannot reach the significant synergistic effect.

The invention discloses a penoxsulam-oxadiargyl compound dispersible oil suspended agent, and a preparation method thereof, and belongs to the technical field of prevention of annual weed in transplanted rice fields. 100 parts of the penoxsulam-oxadiargyl compound dispersible oil suspended agent is prepared from at least 5 parts of penoxsulam, 10 parts of oxadiargyl, 6 parts of sodium methylene bis-naphthalene sulfonate, 2 parts of xanthan gum, 2 parts of ammonium lauryl sulfate, 15 parts of emulsifying agent 602, and the balance methyl oleate. The preparation method comprises following steps: the raw materials are pumped into a preparing vessel for mixing stirring, are subjected to preliminary grinding using a colloid mill, and are subjected to fine grinding using a sand mill; sampling analysis is carried out; and a qualified product is subjected to filtering, weighing, and packaging, and then is put in storage. The 15% penoxsulam-oxadiargyl compound dispersible oil suspended agent prepared at a penoxsulam / oxadiargyl ratio of 1:2 is capable of achieving obvious synergistic effect in preventing annual weed in transplanted rice fields, and the penoxsulam-oxadiargyl compound dispersible oil suspended agent prepared at other penoxsulam / oxadiargyl ratio is not capable of achieving obvious synergistic effect.
