A liquid agrochemical comprising 1 to 11% by weight of a pyridazine compound of formula (I): Wherein R1 is a chloro atom, bromo atom, cyano group or methyl group； and R2 is a hydrogen atom or fluoro atom. The liquid agrochemical also comprises 1 to 30% by weight of a surfactant as well as a total content of 50 to 98% by weight of benzyl alcohol and aromatic hydrocarbon. The weight ratio of benzyl alcohol to the aromatic hydrocarbon(s) is within the range of 30:70 to 85:15. Preferably the aromatic hydrocarbon(s) is at least one alkylbenzene or at least one alkyl naphthalene. The surfactant may comprise a combination of a non-ionic surfactant and an anionic surfactant such as dodecylbenzene sulfonate in combination with polyoxylalkylene polyaryl ether or polyoxyalkylene alkyl ether. In one embodiment the liquid agrochemical is an emulsifiable concentrate.
