Serrano golden

Serrano golden is a significant phytopathogen, classified within the family Geminiviridae. It functions as a virus with a circular single-stranded DNA genome, capable of causing devastating systemic diseases in various solanaceous crops, often leading to severe agricultural yield losses.

The primary hosts of this virus include pepper (Capsicum spp., specifically Serrano types), tomatoes, and wild reservoirs within the Solanaceae family. Infected plants exhibit distinct symptoms such as golden mosaic patterns, leaf curling, stunted development, and the production of deformed fruits, which significantly degrades the crop's market value.

The biological cycle of the virus is intrinsically linked to its primary vector, the tobacco whitefly (Bemisia tabaci). The transmission is persistent; the whitefly acquires the viral particles while feeding on an infected plant, and after a latent period, the virus is transmitted to healthy plants through saliva during subsequent feeding events.

Environmental conditions that favor the proliferation of Bemisia tabaci are the main drivers of the virus's spread. Warm, dry weather conditions facilitate rapid whitefly reproduction, leading to an increased viral inoculum pressure. Consequently, the infection often moves rapidly across fields and can reach epidemic proportions in intensive farming environments.

The economic impact of Serrano golden necessitates rigorous control measures. Growers must adopt an integrated pest management strategy that includes the use of virus-free transplants, physical exclusion barriers like insect nets, systematic weed management to eliminate reservoirs, and effective chemical or biological control of the whitefly population.

• Deployment of resistant or tolerant cultivars
• Regular monitoring of whitefly populations
• Removal and destruction of symptomatic plants
• Application of reflective mulches to deter vectors
