PROCESS FOR THE PREPARATION OF DISPERSIBLE GRANULATES OF FUNGICID PRODUCTS ESPECIALLY BASED ON DERIVATIVES OF THE PHOSPHORUS TYPE

摘要

Fungicidal granules comprise by wt. 5-95 wt. % of a phosphite fungicide, in solid or solidified form, 0.1-8% of a wetting agent, 0.3-15% of a dispersing agent and 0-50% of a support, the granules having a size of 0.1-10 mm. Pref. the granules contain 0.5-5% wetting agent e.g. an alkylaryl-sulphonate salt, a salt of a polycarboxylic acid, a polycondensate of ethylene oxide with a fatty alcohol with a fatty acid or with a fatty amine, a substd. phenol or a salt of an ester of sulphosuccinic acid, and 2-8% of dispersing agent e.g. an arylsulphonate acid, a salt of lignosulphonic acid, a salt of phenolsulphonic, a salt of polyacrylic acid, a salt of lignosulphonic acid, a salt of phenolsulphonic or naphthalene sulphonic acid, a taurine derivative, an alkyl taurate, a phosphoric ester of an alcohol or of a polycondensate of ethylene oxide and a phenol, or an ester of a fatty acid and a polyol, or deriv. of these cpds. which have a sulphate, sulphonate or phosphate function.
