ANTICUERPO CONJUGADO, BEET NECROTIC YELLOW VEIN VIRUS, BNYVV PARA 500 ENSAYOS, 1 TUBO_0.1ML

BNYVV (3) has a narrow host range and is transmitted by the protozoan Polymyxa betae and by mechanical inoculation. It occurs wherever sugar beets are grown and causes a disease of economic importance. The virus causes „rhizomania“ disease of sugar beet. In nature, it infects sugar beet, fodder beet, Swiss chard and spinach. The disease is usually distributed as foci (patches) in the sugar beet field. Symptoms are characterized by root stunting and proliferation of lateral rootlets on the main tap roots, and yellowbrown coloration of vascular bundles. These typical root symptoms give rise to the name „rhizomania“ (“root madness”). In this condition, the bright yellow colour followed by necrosis along veins is giving the virus name „necrotic yellow vein“.
