The vine is predisposed most often to the attack of mannagrass, oidium, and rotting. These are the most dangerous diseases, but the grapevine can be attacked by other diseases such as viroid vines, bacterial cancer, ribbed mosaic, marooning and black vine weevil. The substances used to combat them are the same as those for fighting the main three diseases.
Among the pests, the vine is predisposed to the attack of mites, phylloxera, moth grapes and moth vines. Insecticides and acaricides are used to control the pests. During the vegetation cycle, it is recommended to alternate the insecticides administered to prevent the pests’ resistance to a single insecticide.
Harvesting of vines
Elimination of mannagrass from vineyards is essential for preventing disease and pest attacks.
