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 ...

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.
