Sodium diacetate is a molecular compound of sodium acetate and acetic acid, which has a good effect on the mildew prevention and freshness preservation of cereals, corn and feed. It is also applicable to the preservation of all mixed feeds and their raw materials, and can significantly increase their nutritional efficacy and improve the palatability of animals.

The minimum inhibitory concentration test of the fungicide showed that: during the storage period of the feed, the total number of molds in the feed was sampled and tested every 10 days. The data obtained showed that the number of molds in the control group of the feed sample without the fungicide increased with the increase of the storage time, while the number of molds in the treatment group with the fungicide decreased gradually with the increase of the storage time. The higher the concentration of the mold inhibitor, the faster the mold number decreased, indicating that the sodium diacetate mold inhibitor has obvious inhibition and killing effect on the mold in the feed. 1.0g/kg can effectively prevent mildew.

Sodium diacetate is an effective mildew inhibitor. Its dosage is small. Adding 1.0g/kg to the feed can well inhibit the growth and development of mold, and its action time is lasting. The sensitivity of different molds to sodium diacetate fungicide is different. The experimental verification shows that when the concentration of the fungicide reaches 5.0 g/L, it can basically inhibit various common molds; Fungicide has a strong effect on Aspergillus griseus, Aspergillus fumigatus and Geotrichum candidum, and the concentration of 1.0 g/L can inhibit their growth.
