Water dispersible granules (WDG) are developed on the basis of wettable powders and suspending agents. They are made of pesticides into a dry, dust-free preparation. Form a highly suspended solid-liquid dispersion system. Good physical and chemical stability, especially for pesticides that are unstable in water, dispersible granules are more stable than suspending agents.
The original drug in WDG is a solid original drug that is insoluble in water, and the original drug in WSG is a solid original drug that is soluble in water by itself.
Taking dinotefuran 20% wdg and dinotefuran 20% wsg as examples, the prices of the two are similar, and the efficacy and usage methods are basically the same.
The main difference between the two: dinotefuran 20% wdg is dissolved in water to form a milky white dry suspension, while dinotefuran 20% wsg is dissolved in water to form a relatively transparent aqueous solution.
Water Dispersible Granules - WDG:
Water dispersible granules cannot be dissolved quickly, slow, and completely dissolved after entering water. It is an emulsion, not a true solution. It needs to be stirred in the actual application process, and needs to be dissolved twice to form a granular suspension. The dosage form, even in the actual operation, precipitation occurs, and the utilization rate of active ingredients is low.
Under normal circumstances, the utilization rate of active ingredients, the solubility in water is about 70%, and the utilization rate of active ingredients is 60%. This dosage form is generally in China, not an advanced dosage form, or even a relatively backward dosage form. .
Soluble Granules--WSG:
Soluble granules can disintegrate quickly after entering water, dissolve evenly in water, can be completely diluted, the solution is uniform and stable, the solution is complete, and it can truly form a solution. .
In the process of use, the liquid medicine can be evenly attached to the leaves of plants. It is the most advanced formulation in the world and conforms to the development direction of international pesticide formulations.
