Claim 15:
16. A method for preparing the packaged stable, self-dispersible, low foaming folpet granule of claim 12, comprising:
(i) mixing the folpet with the hydrophobically modified polyacrylate/acrylic copolymer, sodium di-isopropyl naphthalene sulphonate, citric acid, sodium bicarbonate and polysiloxane silicon(e)-based powder antifoam agent to obtain a premix,
(ii) milling the premix to obtain a milled premix,
(iii) wetting the milled premix with granulation water containing 4.5% of the non-ionic polyalkoxylated butyl ether surfactant to obtain a wetted powder,
(iv) extruding the wetted powder in an extrusion granulator to obtain extruded granules,
(v) drying the extruded granules to a moisture content of less than 3%,
(vi) sieving the dried granules, and
packing the granules in a package which is sufficiently impermeable to moisture such that the effervescent system comprised in the granule contained in the package does not substantially react when the package is exposed to humid air.
