Protection methods

There is no curative control method that can effectively control the dandelion ( yellow mosaic virus Dandelion yellow mosaic virus , DaYMV) during cultivation. An infected plant will remain so for its entire life.

The lack of knowledge on the etiology and epidemiology of DaYMV does not allow us to offer you specific preventive control methods for this virus. We therefore suggest that you consult the "Protection methods" section of the other sheets dealing with viruses transmitted by aphids and adopt the proposed measures: elimination of weeds, protection of nurseries against vectors, elimination of the first diseased plants ...

In addition, mechanical transmissions carried out on about twenty varieties of butter lettuce, resistant or not to LMV, did not make it possible to demonstrate any varietal resistance .

NB: Controlling insect populations on a crop implies, depending on the situation, the use of insecticides. As the number of insecticides available for a given use is constantly changing, we advise you to consult the e-phy site of the Ministry of Agriculture and Fisheries which is an online catalog of plant protection products and their uses, materials. fertilizers and growing media approved in France . This also applies to all biological products based on microorganisms or natural substances.
