Collar Rot of Grapevine Caused by a Novel <em>Pleiocarpon</em> Lineage in Peru

2026-05-06

Abstract excerpt

Severe decline and death of young table grape vines (1 to 2 years old) have been observed recurrently in commercial vineyards in Peru since 2022. Affected plants developed rapid shoot wilting associated with extensive necrotic lesions at the rootstock collar below the graft union, leading to plant death within days of symptom onset. A Cylindrocarpon-like fungus was consistently isolated from symptomatic collar tis...
