| 摘要 |
The invention concerns a method for preparing phytosanitary compositions in solid form, which consists in grinding a suspension containing at least an active phytosanitary substance, at least a surfactant and at least an anti-foaming agent, followed by spray-drying to obtain a phytosanitary composition in solid form. The method consists in grinding a suspension comprising at least an anti-foaming agent selected among silicone substances having a viscosity not less than 8 Pa's. The anti-foaming agent used in the invention has the advantage of preserving its properties, not only during the preparation of the phytosanitary composition but also when the latter is used (dilution/dispersion). |
