KIT DIAGNÓSTICO ELISA, PRSV PARA 480 ENSAYOS, 1 KIT

PRSV (2) is transmissible mechanically, and by numerous species of aphid in a non-persistent manner. Most strains belong to one of two major types, which are serologically very closely related. Type P (papaya-infecting) isolates cause an important disease in papaya and also occur in cucurbits. Type W (= watermelon mosaic virus 1) isolates cause important diseases in watermelon and other cucurbits, but do not infect papaya. The virus is widely distributed throughout the world. In papaya, type P isolates cause mottling and distortion of leaves, rings and spots on fruit, and streaks on stems and petioles. Plants are stunted and fruit set is reduced.
