Ipomovirus

Ipomovirus is a genus of plant viruses in the family Potyviridae, known for causing significant systemic diseases in various vegetable crops. These viruses are characteristically transmitted in a semi-persistent manner by specific insect vectors, which complicates control efforts in agricultural production.

The primary hosts of Ipomovirus include essential vegetable species within the Solanaceae and Cucurbitaceae families. Crops such as tomatoes, cucumbers, peppers, and squash are highly susceptible, often experiencing severe physiological stress that leads to substantial reductions in harvest quality and volume.

The clinical signs of infection typically include interveinal chlorosis, mosaic patterns on leaves, stunted development, and leaf deformation. Fruit quality is also frequently compromised, as the virus can cause blotchy ripening and irregular surface symptoms, making the produce commercially unviable.

The development and spread of the disease are intrinsically linked to the activity of whiteflies, which act as the main vectors for transmission. High greenhouse temperatures and humidity levels create favorable conditions for vector proliferation, facilitating the rapid movement of the virus throughout the crop.

Effective management requires an integrated approach. Recommended strategies include:

• Rigorous control of whitefly populations using biological and chemical methods.
• Utilization of resistant plant cultivars.
• Strict sanitation protocols in greenhouse facilities.
• Early detection and roguing of infected plant material to minimize viral spread.
