Solanum aureicontorsion gold curl

The causal agent of this disease is the Begomovirus solanumaureicontorsionis, a member of the Geminiviridae family. As a viral pathogen, it induces systemic infections that disrupt the plant's hormonal balance and vascular integrity, significantly compromising overall plant health.

This virus primarily targets Solanaceous crops, including tomatoes, peppers, and eggplants. The host range is broad enough to include various weed species, which act as reservoirs that maintain the viral load in the environment throughout the growing season.

Infected plants typically display severe leaf curling, twisting, and a distinct golden-yellow discoloration, known as chlorosis. The impact on growth is severe, characterized by stunted internodes, stunted overall plant stature, and a drastic reduction in fruit setting or fruit quality.

Transmission of the virus is strictly linked to insect vectors, primarily the whitefly (Bemisia tabaci). The epidemiology of the disease is dictated by the population dynamics of these insects, which thrive in warm, humid conditions, facilitating the rapid spread of the virus across fields.

• Rigorous whitefly population monitoring and management.
• Use of virus-resistant or tolerant crop varieties.
• Implementing strict weed control to remove alternative hosts.
• Applying physical barriers like insect-proof netting in greenhouses.
• Sanitation practices to prevent virus transmission by mechanical tools.
