Example Embodiment
[0017] Specific embodiment 1: The water-dispersible granular seed coating agent of this embodiment is composed of 5-40 parts by mass of the original fungicide, 0-40 parts of the original pesticide, 4-8 parts of the dispersant, 1 ~3 parts of wetting agent, 1~5 parts of disintegrant, 5~20 parts of film-forming agent, 0.5~4 parts of coloring agent and 0~40 parts of carrier; wherein the fungicide original drug is fludioxonil , Indazole sulfonamide, inoconazole, carbendazim, thiram and tebuconazole or a combination of several of them, and the original pesticide is chlorpyrifos and / or matrine.
Example Embodiment
[0018] Specific embodiment two: this embodiment is different from specific embodiment one in that the dispersant is sodium lignosulfonate, sodium salt of alkyl naphthalene sulfonic acid condensation polymer (D-425), sodium n-butyl naphthalene sulfonate (MorwetB), sodium diisobutyl naphthalene sulfonate (open powder BX) and sodium 1-methylnaphthalene sulfonate (MF) or a combination of several of them. Others are the same as the first embodiment.
[0019] When the dispersant of the present embodiment is a composition, the respective dispersants are combined in an arbitrary ratio.
Example Embodiment
[0020] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the wetting agent is alkyl naphthalene sulfonate (Morwet EFW), sulfosuccinate (Lankropol KPH70) and dodecyl One or a combination of sodium sulfate (SDS). Others are the same as the first or second embodiment.
[0021] When the wetting agent of this embodiment is a composition, each wetting agent is combined in an arbitrary ratio.
