Solanumpalampurense begomovirus

Solanumpalampurense begomovirus is a significant plant pathogen within the Begomovirus genus of the Geminiviridae family. It causes severe systemic diseases that disrupt the development of various horticultural plants, particularly within the Solanaceae family.

This virus primarily infects tomato plants and peppers, leading to major economic losses in agricultural regions. Because the virus alters plant physiology, infected crops show drastically reduced yields and poor fruit quality, making early detection vital for managing the disease effectively.

Symptoms of infection are quite distinct and include leaf curling, yellow mosaic patterns on the foliage, stunted internodes, and stunted plant growth. In many cases, the affected fruits display discoloration and irregular shapes, rendering them unsuitable for commercial sale or processing.

Transmission occurs through the whitefly (Bemisia tabaci), which acts as the primary vector. The virus is acquired by the vector during feeding and is then efficiently transmitted to healthy plants. Understanding the life cycle of the whitefly is crucial for predicting and preventing outbreaks within greenhouses and open fields.

Effective management requires an integrated pest management (IPM) approach. This involves the use of virus-free planting stock, the implementation of physical barriers such as insect-proof netting in greenhouses, and the strategic application of insecticides to control whitefly populations. Additionally, removing alternate weed hosts near production areas is essential to minimize the risk of recurring infections.
