Begomovirus sidaureilaraense

Affected plants often exhibit leaf deformation, including curling, crinkling, or a rugose texture that inhibits normal leaf expansion.

General growth retardation is a hallmark of this disease, resulting in stunted overall plant height and reduced biomass accumulation.

Shortened internodes and bushy appearance are commonly observed in advanced stages, significantly altering the plant's structural development.

Severe infections may lead to premature senescence and tissue necrosis, which can result in the loss of foliage and reduced photosynthetic efficiency.

The disease is caused by a virus belonging to the genus Begomovirus within the Geminiviridae family, which contains a circular single-stranded DNA genome.

As an obligate parasite, the virus requires the host's cellular machinery to replicate and spread throughout the vascular tissues of the plant.

The virus is classified as a systemic pathogen, meaning it establishes a chronic infection that affects the entire host organism.

Its biological structure is highly stable, allowing it to persist in various environmental conditions as long as a suitable host is available.

The high mutation rate typical of begomoviruses contributes to their rapid evolution and ability to overcome host plant defense mechanisms.

The transmission and spread of the virus are strictly dependent on the presence of insect vectors, primarily whiteflies of the Bemisia tabaci complex.

High temperatures and high humidity create optimal conditions for rapid vector reproduction, leading to increased viral pressure in the field.

Agricultural practices such as monoculture and continuous cropping facilitate the buildup of viral inoculum in the environment.

Weed hosts surrounding crop fields act as primary reservoirs, allowing the virus to survive between planting seasons.

Wind-assisted dispersal of viruliferous insects allows the virus to migrate rapidly across large agricultural landscapes to infect healthy crops.

The economic impact of the virus is significant, primarily due to the substantial reduction in yield quantity and market-grade quality.

Infected crops often fail to reach their full potential, producing smaller or deformed fruits and seeds that are unsuitable for commerce.

Plants affected by the virus display increased vulnerability to abiotic stress, such as drought, heat waves, and nutrient deficiencies.

The disease can lead to widespread crop failure in commercial operations, causing major financial losses for growers and producers.

The persistence of the virus in the environment means that it poses a chronic threat to the long-term sustainability of sensitive crop varieties.

Effective management focuses on the integrated control of the insect vector populations to prevent the transmission of the virus particles.

The use of systemic insecticides is a crucial strategy to limit the colonization and feeding activities of whiteflies on susceptible crops.

Sanitation practices, including the eradication of weeds and the removal of infected plant debris, are essential for reducing inoculum sources.

Breeding and utilizing virus-resistant cultivars remain the most durable and sustainable methods for long-term disease management.

• Deployment of physical barriers like insect-proof netting in greenhouses.
• Implementation of crop rotation to break the cycle of infection.
• Regular monitoring of insect vector populations using yellow sticky traps.
