South Chungcheong Agricultural Research & Extension Services Emphasizes Thorough Prevention and Rapid Response Due to Fast Infection Rate and Difficult Control

On the 10th, the Chungcheongnam-do Agricultural Research & Extension Services (ARES) announced prevention and early response methods for 'Melon Necrotic Spot Virus' after recent reports of its occurrence in melon cultivation areas within the province.

This virus is transmitted through seeds, contaminated soil, fungal species (Olpidium spp.), and contact with sap from infected plants. It is classified as a viral disease that spreads very quickly and is difficult to control once it occurs.

In the initial stages of infection, small yellowish spots appear on young leaves. As it progresses, it can lead to severe damage, including brown necrotic symptoms across the entire leaf, eventually resulting in the plant's death. This causes not only a simple reduction in yield but also a decline in melon quality and loss of marketability, leading to significant economic losses for farmers.

Prevention is paramount for this disease. To prevent infection, using certified healthy seeds and seedlings is the top priority.

Any suspected infected plants should be immediately removed and discarded to prevent further spread to nearby plants. Before transplanting, thorough soil disinfection must be carried out, and tools used for agricultural tasks such as pinching and vine training must be disinfected before and after use.

Kwon Mi-kyung, head of the Watermelon and Melon Team at the Fruit and Vegetable Research Institute, stated, "Preventing this virus goes beyond simple control; it starts with systematic farm hygiene management. Only thorough implementation can prevent damage, so we ask for the active cooperation of farmers."
