SET REACTIVOS ELISA, CTV PARA 480 ENSAYOS, 1 KIT

CTV (2) occurs worldwide wherever citrus is growing and is the economically most important viral disease of citrus. It has a narrow range of hosts mostly restricted to citrus species. The virus is transmitted by aphids in a semi-persistent manner. Important aphids are “the brown citrus aphid” (Toxoptera citricida) and “the melon aphid” (Aphis gossypii).

There is a great diversity of symptoms; the severity depends on the virus strain and on the host (often also on the scion-rootstock combination). Symptoms include declining (e.g. on sour orange rootstocks), seedling yellows, stem pitting, loss of vigour, wilting, stunting, yellow-brown staining at bud union and on inner surface of bark, etc. up to complete die-back (e.g. of limes irrespective of rootstocks).
