Prevention

Solution Production stage (if possible with reference to BBCH scale)
For virus diseases transmitted by aphids in a non-persistent way (including cucumber mosaic virus, CMV), insecticides on crop against aphids aren't able to prevent viruses transmission.
For virus disease transmitted by seeds (lettuce mosaic virus) it is extremely important to use healthy seeds (certified virusfree).
Sowing
use plants coming from nurseries that applied strategies against thrips vectors, particularly where both vegetable and flower crops are present (against Tospovirus)
Sowing/Planting
In accordance with the general rules about weeding, remove weeds in and around crop (weeds could be a source of viruses, vectors or both) (against Tospovirus)
From Sowing/Planting to Harvest

Monitoring

Solution
if plants is coming from infested areas, verify the absence of any symptoms and/or thrips (against Tospovirus)
if suspected syntoms develop, got to lab
