| 摘要 |
The formation of undesirable sludge in the course of spraying a solution or dispersion of a water-soluble or water-dispersible solid or a structured gel formulation is reduced by the incorporation in the formulation of a low-density solid particulate material having a density of less than one and a diameter of less than the spray nozzle filter through which it will pass. The low-density solid particulate material is preferably a hollow glass or plastic particle having a density of less than 0.8 g/cm3. The invention is particularly applicable to agrochemical formulations.
