The invention relates to the field of
pesticide preparations, and discloses a
pesticide composition and the preparation thereof. The
pesticide composition provided by the invention consists of diflufenican and
thiamethoxam the
mass ratio of which is (2-20):(5-30). A suspension seed dressing provided by the invention comprises: 2-20% of diflufenican, 5-30% of
thiamethoxam, 1-8% of
wetting dispersion agent, 0.5-10% of film-forming agent, 1-10% of coloring agent, 0.1-2% of
thickening agent, 1-5% of anti-freezing agent, 0.1-1% of
antiseptic agent, 0.1-1% of defoaming agent, and the balance of
distilled water. According to the invention, the complex diflufenican and
thiamethoxam acts as the
active ingredient of the suspension seed dressing, the advantages of diflufenican and thiamethoxam are complementary, the
insect prevention spectrum of the medicaments can be expanded, the pesticide effect is improved simultaneously, multiple
insect damages can be prevented and treated by medicament use once, the using amount, types and times of the pesticide are reduced, and the pesticide composition and the preparation can be widely used in the agricultural filed.
