The invention discloses a thiediazole
copper water dispersible granule and a preparation method thereof. The thiediazole
copper water dispersible granule comprises the following raw materials in parts by weight: 10-60 parts of thiediazole
copper, 1-8 parts of a
wetting agent, 1-8 parts of a dispersant, 1-30 parts of a disintegrating agent, 0.5-5 parts of a binding agent, 0.5-5 parts of a defoaming agent, 0.5-5 parts of a
plant growth regulator, 0.5-3 parts of synergist and the balance of filler to 100 parts. The preparation method comprises the following steps: uniformly mixing the thiediazole copper with various auxiliary materials according to proportions, and
grinding a mixture through a grinder to obtain mother
powder; uniformly mixing the mother
powder with a binding agent water solution, pelleting, forming and
drying; and sieving dried granular materials, discharging materials after analyzing and inspecting to be qualified, packaging and storing. The thiediazole copper
water dispersible granule disclosed by the invention, as an organic copper broad-spectrum
fungicide, has a good effect on preventing and controlling various bacterial and fungal diseases; the thiediazole copper water dispersible granule is free from
pollution and residue to crops, and the preparation disclosed by the invention has the advantages of good disintegration, high suspension rate and stable heat storage performance.
