Cucumber Mosaic Virus on Cucumber

Cucumber mosaic virus
Barbados
  • If possible, remove host weeds but the host range for CMV is over 1200 species.
  • When possible, do not plant in previously infected areas. Common crop hosts are spinach, pepper, celery, tomato and lettuce.
  • Sanitize tools and machinery. The virus is mostly aphid transmitted but can be transmitted between plant with tools.
  • Try to plant in areas which do not suffer so greatly from aphids.
  • Check plants approx. 7 days after planting for aphids
  • Check for ants as this may be a sure sign that aphids are present
  • Symptoms include: stunting of plants, narrowing, curling downwards and mottling of leaves, and distorted and greyish looking fruit
  • Take action when you see 7 or more aphids per plant
  • There is no known control for viruses. Control of aphids is necessary as it is the main vector for CMV.
  • Remove diseased plants from the field by placing in a plastic bag before removing from the field and disposing of them. There is nothing to be gained by only removing those parts showing symptoms.
  • Leave bag in direct sunlight to kill aphids.
  • PPE should be worn when applying pesticides
