CONTROL POSITIVO, TYMV, 1 TUBO_2,5ML

TYMV (4) (Synonym: Cardamine yellow mosaic virus) only infects crucifers. Main affected crops are different cruciferous plants such as turnips, cabbages, mustards, rapes etc. In cauliflower, symptoms begin as vein clearing but later and on older leaves, permanent yellow patches develop. Symptoms on Chinese cabbage develop as bright yellow and dark green mosaic patterns. During cool weather, infected plants remain stunted. Symptoms are mild in other “brassicas”. The virus is transmitted by chewing insects such as beetles, grasshoppers and earwigs.
