Viruses of asparagus

Area of Science:

• Plant Pathology
• Virology
• Horticultural Science

Background:

• Asparagus (Asparagus officinalis) is susceptible to various viral infections.
• Over fifty years, nine virus species from six genera have been identified in asparagus crops.
• Asparagus virus 1 (AV1) and Asparagus virus 2 (AV2) are particularly prevalent.

Purpose of the Study:

• To review the current knowledge on viruses affecting asparagus.
• To detail the properties, epidemiology, and diagnostics of major asparagus viruses.
• To provide a brief overview of minor viruses and control strategies.

Main Methods:

• Literature review of scientific publications on asparagus viruses.
• Synthesis of information on virus identification, characteristics, and impact.
• Description of diagnostic techniques for virus detection.

Main Results:

• Nine virus species across six genera have been identified in asparagus.
• AV1 (Potyvirus) and AV2 (Ilarvirus) are widespread and economically damaging.
• These viruses reduce yield and increase crop susceptibility to other stresses.

Conclusions:

• AV1 and AV2 pose significant threats to commercial asparagus production.
• Effective diagnostic methods are crucial for managing these viral diseases.
• Further research into control strategies for asparagus viruses is warranted.
