CONTROL POSITIVO, ARMV, 1 TUBO_2,5ML

ASGV (5) is a virus with flexuous filamentous particles. It probably occurs world-wide in Rosaceae fruit trees and citrus in which it is usually symptomless. Its natural mode of spread is unknown. It is symptomlessly in most Rosaceae fruit trees and citrus plants. Transmissible by mechanical inoculation to herbaceous plants. It causes stem grooving, brown line and graft union abnormalities in Virginia Crab, topworking disease of apple trees grown on Mitsuba kaido (Malus sieboldii) in Japan, and bud union abnormalities of citrus trees on trifoliate orange. It is probably distributed wherever apples are cultivated. Natural spread in citrus plants is reported in China and Japan.
