Solanum patnaense begomovirus

Begomovirus solanumpatnaense is a plant pathogenic virus belonging to the genus Begomovirus within the Geminiviridae family. These viruses are characterized by their circular single-stranded DNA genome and are well-known for causing significant agricultural damage globally by disrupting host cell functions.

The host range of this virus primarily includes members of the Solanaceae family. Economically important crops such as tomatoes, peppers, and potatoes are highly susceptible to the infection. The virus colonizes the phloem tissues, which leads to systemic infection throughout the plant.

The most common symptoms include severe leaf curling, yellowing (chlorosis), and stunted growth of the plant. Leaves often display puckering or rugosity, and internodes become shortened. These physiological changes severely limit the plant's ability to undergo photosynthesis and result in poor fruit development and yield loss.

The transmission of Begomovirus solanumpatnaense is strictly mediated by the whitefly Bemisia tabaci. The virus is acquired by the insect while feeding on the phloem of an infected plant and is subsequently transmitted to healthy plants. High temperatures and high humidity levels facilitate the rapid spread of the vector, leading to widespread epidemics.

• Implement strict sanitation measures to remove alternative weed hosts.
• Use certified virus-free seedlings and resistant cultivars.
• Deploy systematic insecticide programs to control the whitefly vector population.
• Utilize physical barriers like insect-proof nets in greenhouses.
• Monitor insect populations consistently to prevent localized outbreaks.

Effective management requires an integrated pest management (IPM) strategy. Because there is no direct chemical cure for viral infections in plants, the primary goal must be the elimination of the vector and the removal of infection sources to prevent the initial introduction of the virus into the field.
