The invention discloses a composition containing pyridalyl and tetratolfenpyrad, and belongs to the technical field of pesticide synthesis. The composition comprises the following raw materials by weight: 1-50% of pyridalyl, 1-50% of tetratolfenpyrad, 5-15% of a synergist, 0.1-3% of polyethylene glycol, and the balance of water; wherein the pyridalyl and the tetratolfenpyrad have a certain insecticidal effect, a synergist is prepared in the preparation process of the composition, the synergist is used for reducing an intermediate 6 to prepare an intermediate 7, the intermediate 7 reacts with phosgene to prepare an intermediate 8, the intermediate 8 reacts with 2, 2, 2-trifluoroethanol to prepare an intermediate 9, the intermediate 9 is subjected to microspheroidizing treatment; and thus, the synergist is prepared, the synergist can block nerve conduction to enable insects to die, then the insecticidal effect of the composition is further improved, and the pesticide effect is further prolonged through microspheroidizing.
