ANTICUERPO IGG,LEEK YELLOW STRIPE VIRUS, LYSV PARA 500 ENSAYOS, 1 TUBO_0.1ML

LYSV (2) is transmitted by aphid species in the non-persistent manner and by inoculation with sap. The virus infects leek and a few other Allium species. In nature, the virus seems largely limited to leek in which it causes irregular yellow striping of the whole lamina, but especially at its base. Whole leaves may also be yellow. Affected plants are less juicy and weigh less than normal, the leaves are slightly flaccid, the white stems are lustreless and the keeping quality of the harvested product is impaired. Infected plants in autumn and winter crops suffer more than healthy plants from frost and may be killed. Leaf streaking is more white and severe when the plants are also infected with shallot latent virus. The occurence of the virus has been reported from several European countries and New Zealand
