‘Red Globe’ grafted on the rootstock IAC 572 |
Disease incidence: 70–80% of diseased plants |
The symptoms observed in the field were cankers on twigs as well as brown to black leaf spot lesions surrounded or not by a chlorotic halo, sometimes along the veins, and numerous depressed dark lesions on berries. In some cases, a pale white exudation was observed over the lesions. |
Tupi Paulista county, São Paulo, Brazil in 2009 It was assumed that the disease had been introduced through infected propagating material for grafting obtained from the Petrolina region in 2001. In the same property another plot was cultivated with ‘Niagara Rosada’ (Vitis labrusca x vinifera hyb.), but no bacterial infection was detected. No symptoms were observed on the sprouts emerging from rootstocks in the infected plot of ‘Red Globe’. The pathogen has been eradicated from the State of São Paulo. |

Seedless cultivars Red Globe, Brasil, Piratininga, Patrícia, Benitaka, Ribier and Catalunha |
Disease observed 2–3 years after grafting. 100% disease incidence on ‘Red Globe’ and other seedless cultivars. Variable disease incidence in cultivars Itália, Festival, Brasil, Piratininga, Patrícia, Benitaka, Ribier and Catalunha. The cultivars Itália and Benitaka appear more tolerant |
Initially, the disease was found in 2–3 years old plants, but the disease was later found in older plants. Abundant epiphytic colonisation of the pathogen was detected on both symptomatic and asymptomatic vines and leaves. From one production cycle to the next one the bacteria survive in infected plants as epiphyte/endophyte. |

‘Red Globe’ (207 = 58%), ‘ltàlia’ (51 = 14,2%), ‘Festival’ (19 = 5,3%), ‘Piratininga’ (11 = 3,1%), ‘Benitaka’ (10 = 2,8%), ‘Catalunha’ (8 = 2,2%) and others (52 = 14,5%). |
From 358 analysed samples, Xcv was detected in 197 (55%), from Bahia, Piaui and Pernambuco. | 1998–1999, a total of 358 grapevine samples analysed, 290 from Pernambuco, 63 from Bahia, 3 from Piaui, 2 from Minas Gerais, Brazil | Lima et al. (2000) | ||
‘Red Globe’ on the rootstock Tropical 576 |
100% diseased plants | 3–4 years old with typical symptoms |
Latent infection in rootstocks Brazil |
Lima and Ferreira (2000) | |
Young plants (2–3 years) Mainly in seedless cultivars Red Globe and Thompson Seedless, Found disease foci in cvs. Itália, Festival, Brasil, Piratininga, Patrícia, Benitaka, Superior and Catalunha. |
100% diseased plants | Plants with symptoms as necrotic spots, with or without halo and necrotic leaf areas, necrotic veins, dark spots along the petiole and cankers. | São Francisco Valley, Bahia, Brazil | Lima et al. (1998) | |
Seedless cultivars Red Globe, Thompson Seedless. Other cultivars: Italia, Festival, Piratininga, Patricia, Ribier, Catalunha, Brasil and Benitaka. |
‘Red Globe’ and the seedless cultivars originated from ‘Thompson Seedless’, on which the incidence was nearly 100% diseased plants. Variable disease incidence on ‘Italia’, ‘Festival’, ‘Piratininga’, ‘Patricia’, ‘Ribier’, ‘Catalunha’, ‘Brasil’ and ‘Benitaka’. Cultivar Italia showed tolerance to the disease under field conditions. |
Symptoms of stem canker and necrotic spots on leaves, leaf veins, petioles, rachis, peduncles, cap stems and berries were observed on plants | Nearly complete yield loss | Plants in vineyards in the ‘Subrnédio’ of the São Francisco Valley, Brazil | Lima et al. (1999) |
Seedless cultivars Thompson Seedless, Tas‐e‐Ganesh, Sonaka and Manik Chaman |
Symptoms in leaves, petioles and canes |
Disease causes about 60–80% yield loss in severely affected vineyards |
Optimal conditions for pathogen development are temperatures between 25–30°C and high humidity. Maharashtra, Andhra Pradesh and Karnataka, India |

Bijapur, India The field trials were laid out in ten years old vineyards, spaced under different disease control treatments 60% disease index resulted in non‐treated plants. |
