DAWN is a nano encapsulated plant extract product that is highly effective against white spot syndrome virus in shrimp. The encapsulation of natural plant extract enhances the antiviral activities and leads to excellent bioavailability and long-term stability of the formulation. The interaction between the extract and the envelope protein leads to the deactivation of viruses while the plant extract prevents the replication of the virus. The formulation stimulates the multiplication of potent immunostimulatory activity in the host cells of the shrimp.
