The pest pest control composition which shows the insecticidal active level which improves, method in order to manufacture those is disclosed. At one of execution form, method, includes the process which offers the liquid composition which at least includes one which improves the insecticidal activity of the composition at least one agricultural chemical, and in comparison with the composition where just at least not having possessed one auxiliary component differs auxiliary component. This at least one auxiliary component, at least one metallic oxide, at least one transition metal salt and at least combination of one protein characteristic material, or at least one protein characteristic material and may include the combination of one polymer characteristic material at least. This method furthermore, spraying drying the liquid composition, the process which offers the solid composition is included. The solid composition which was offered in one feature of this execution form, by spray drying, shows the insecticidal activity which improves by comparison with the liquid composition.向上した殺虫活性レベルを示す有害生物防除組成物、それらを調製するための方法が開示される。実施形態の1つでは、方法が、少なくとも1つの農薬、及び少なくとも1つの補助成分を有していないことだけが相違する組成物に比べて組成物の殺虫活性を向上させる少なくとも1つの補助成分を含む液体組成物を提供する工程を含む。この少なくとも1つの補助成分が、少なくとも1つの金属酸化物、少なくとも1つの遷移金属塩及び少なくとも1つのタンパク性材料の組み合わせ、又は少なくとも1つのタンパク性材料及び少なくとも1つのポリマー性材料の組み合わせを含んでいてもよい。この方法がさらに、液体組成物を噴霧乾燥して、固体組成物を提供する工程を含む。この実施形態の1つの態様において、噴霧乾燥によって提供された固体組成物が、液体組成物に比較して向上した殺虫活性を示す。
