Anticuerpo IgG, Apple stem pitting virus, ASPV para 500 ensayos, 1 tubo_0.1ml

ASPV (1) (Synonym: Pear vein yellows virus (PVYV)) occurs world-wide. Infection is usually latent in many cultivars and goes unnoticed, despite its high frequency. The virus causes significant, though insidious losses. Often in complex with other latent apple diseases (ACLSV, ASGV, etc.) this affection is the main cause of a decrease in yield quality and quantity. The fruits of infected trees show more russetting and the trees are more fragile and sensitive to canker and nutrient deficiency. ASPV is not epidemic, but is transmitted by grafting.
