PESTICIDE FORMULATIONS AND PROCESS FOR THE MANUFACTURE THEREOF

摘要

1. An aqueous suspension containing: 0.1-20 % by mass beta-cypermethrin, 0-40 % by mass other pesticide substances, 1-10 % by mass surface-active substances in total and within this, 1-5 % by mass ethoxylated polyaryl-phenol-phosphate or sulfate, 0.1-25 % by mass mineral and/or synthetic silicates, 0.1-1 % by mass synthetic silicic acid and up to 100 % by mass other auxiliary materials and water as dispersant. 2 Aqueous suspension according to Claim 1 containing as ethoxylated polyaryl-phenol-phosphate, ethoxylated tristyryl-phenol phosphate with 16 EO-unit. 3. Aqueous suspension according to Claim 1 containing kaolin as silicate. 4. Aqueous suspension according to Claim 1 containing as surface active substance 1-5 % by mass non-ionic surfactant, preferably ethoxylated suspension according to Claim 1 containing as other auxiliary substance 0.1-1 % by mass thickener, preferably xanthan gum, 5-20 % by mass antifreeze substance preferably propylene glycol, basic compound(s) preferably triethanolamine, 0.1-1 % by mass antifoaming agent, preferably silicone type defoamer, 0.01-1.0 % by mass preserving substance, preferably formaldehyde. 5. Process for the preparation of an aqueous suspension according to Claim 1 characterized by grinding beta-cypermethrin together with mineral and/or synthetic silicates, being used in an amount close to the amount of beta-cypermethrin and with ethoxylated polyaryl-phenol-phosphate or sulfate and synthetic silicic acid.
