Celery mosaic virus can pick up the virus on its stylet (its mouthparts) and transfer it quickly to the next plant it probes. The virus can also be transmitted mechanically by tools and machinery. At least 26 different aphid species are known to transmit the virus. There is no evidence of seed transmission. Because chemicals are not effective in treating plant viruses, management of celery mosaic virus focuses on reducing aphid population within colonies of plants. Recommendations for management of celery mosaic virus include planting resistant cultivars, spreading out crops, clearing weeds from crop fields, and treating crops with pesticides.Because celery mosaic virus
