1. Antiviral Effect of Vincx On Sweet Potato

Five days after applying Dora VineX™ to sweet potatoes, symptoms like leaf curling and protrusions caused by the virus are significantly reduced, with new leaves displaying no signs of viral infection.

Key Observations:

  • Rapid Symptom Alleviation: Within a mere five days of applying Dora VincX™, the detrimental effects of the virus, including leaf curling and protrusions, were significantly reduced. This quick response time is crucial for preventing the spread of the virus and minimizing potential yield losses.
  • Protection of New Growth: Most notably, new leaves emerging after the application showed no signs of viral disease. This indicates that Dora VincX™ not only helps in managing the symptoms of already affected plants but also plays a protective role in safeguarding new growth from viral attacks.
  • Sustained Health and Vigor: The absence of viral symptoms in new leaves suggests that Dora VincX™ supports the sustained health and vigor of sweet potato plants, potentially leading to improved yield quality and quantity.
