Control positivo, RBDV, 1 tubo_2,5mL

RBDV is readily transmissible by inoculation of plant sap and infects a wide range of plants, often symptomlessly. It is seed- and pollen-borne in Rubus and spreads between plants in association with pollen. No vector is known.The virus is involved with others in inducing the disease known as ‘bushy dwarf’, or ‘symptomless decline’ in Lloyd George red raspberry; affected plants are characterized by stunting and proliferation of canes and are prone to autumn fruiting.

In sensitive Rubus species and cultivars, RBDV is the causal agent of yellows disease. Premature defoliation, decreased vigour, leaf curling, necrosis, death of lateral shoots and increased winter kill are associated with infection by some isolates of the virus in some red raspberry cultivars.
