冠瘿病主要发生在酿酒葡萄（葡萄属vinifera L.）安大略葡萄园的栽培品种。虫瘿通常很小，沿着树干和甘蔗聚集;大的木质虫瘿较少见。受根癌病影响的葡萄树在种植后3-4年死亡。从虫瘿中分离的所有9株根癌农杆菌（Smith和汤森）Conn在测定试验中对应于生物型3，并且对曼陀罗、烟草、番茄和向日葵植物具有致病性。在改良Stonier培养基上，8株菌对Agrocin 84敏感。它们被抑制，如果接种前6小时之前由辐射农杆菌菌株K84在曼陀罗和番茄植株的伤口部位。
Crown gall was found mostly on vinifera grape (Vitis vinifera L.) cultivars in Ontario vineyards. The galls were usually small and aggregated along the trunk and cane; large woody galls were less common. Vines affected by crown gall died back in 3–4 years after planting. All the nine strains of Agrobacterium tumefaciens (Smith and Townsend) Conn isolated from galls corresponded to biotype 3 in determinative tests and were pathogenic on Datura, tobacco, tomato, and sunflower plants. Eight strains were sensitive to agrocin 84 on amended Stonier's medium. They were suppressed if inoculation was preceded 6 h earlier by Agrobacterium radiobacter strain K84 at wound sites on Datura and tomato plants.
