biomechanical assessment of new hand powered Pruning Shears
Applied Ergonomics, 2004Co-Authors: Yves Roquelaure, Fabian Despagnac, Yves Delamarre, D PenneaufontbonneAbstract:The aim of the study was to assess the biomechanical strains on the hand–wrist system during grapevine Pruning with newly designed Pruning Shears. Surface electromyography of the finger flexor muscle and wrist postures were analyzed in four vineyard workers during actual work with the new and reference hand-powered Pruning Shears. Due to the large inter-individual differences in biomechanical data observed with both Pruning Shears, no systematic effect of the new Pruning Shears on “extreme” flexion/extension (F/E) and ulnar/radial (U/R) wrist deviations was demonstrated. However, the use of the new Pruning Shears was associated with a higher frequency of “neutral and moderate” U/R deviations (U/R < 20%max) and, to a lesser extent, of “neutral and moderate” F/E deviations (F/E < 20%max). Due to the small sample of workers, this result must be confirmed in a larger population of vineyard workers.

transient hand paresthesias in champagne vineyard workers
American Journal of Industrial Medicine, 2001Co-Authors: Yves Roquelaure, Sean Fanello, Y Gabignon, J C Gillant, P Delalieux, M Mea, C. Ferrari, D PenneaufontbonneAbstract:Background The aim of the study was to assess the prevalence of hand paresthesias (HP) and their relationship with Pruning activities. Methods A cross-sectional study was conducted among 537 workers Pruning grapevines in the region of Champagne. All workers completed a questionnaire about nocturnal HP and musculoskeletal pain during the preceding 12-month period. Results The 12-month prevalence of nocturnal HP and hand-wrist pain were 37 and 12%, respectively. HP, predominantly affecting the dominant hand, only began during the Pruning period and ended after the Pruning season in 90% of cases. HP were transient in most cases, with a mean duration of symptoms of 3.3 ± 3.2 months. Risk factors associated with HP were: female gender (OR = 2.3 [1.3–3.0]), being overweight (OR = 1.6 [1.1–2.5]), payment on a piecework basis (OR = 2.0 [1.2–2.3]) and traditional blade sharpening method (OR = 1.7 [1.1–2.7]). HP were less frequent in employees who used electric Pruning Shears (OR = 0.5 [0.2-1.6], P = 0.09). Conclusions The development of HP, which affected a third of employees, was different from HP observed in industrial workers since most vineyard workers recovered without medical treatment after the Pruning season.

Pruning practices influence infection and dissemination of Calosphaeria pulchella, the cause of Calosphaeria canker of sweet cherry
MEDITERRANEAN PHYTOPATHOLOGICAL UNION, 2018Co-Authors: Berbegal Martinez Monica, Armengol Fortí JosepAbstract:[EN] Calosphaeria canker of sweet cherry, caused by Calosphaeria pulchella, is a limiting factor for sweet cherry production, but the role of Pruning practices on pathogen dissemination remains unknown. Three experimental treatments were compared during summer and winter seasons, to assess their effects on pathogen transmission. The treatments were: i) using disinfected Pruning Shears; ii) Pruning Shears used to cut through diseased branches before each subsequent cut (non-disinfected Pruning Shears); and iii) artificial inoculation of fresh Pruning wounds with C. pulchella. Six months after Pruning, branches were cut from trees for disease assessment and fungal isolation. Pruning with non-disinfected Pruning Shears increased disease incidence and severity, compared with the use of disinfected Shears. Artificially inoculated branches gave the greatest disease incidence and severity. Results from the various treatments were consistent for both winter and summer Pruning. These confirm that frequent disinfection of Pruning tools is advised for the effective management of Calosphaeria canker of sweet cherry.This research was funded by the Cooperativa Agricola Villena (Alicante, Spain).Berbegal Martinez, M.; Armengol Fortí, J.

Detection of grapevine fungal trunk pathogens on Pruning Shears and evaluation of their potential for spread of infection
'Scientific Societies', 2015Co-Authors: Agustí Brisach Carlos, León Santana Maela, García Jiménez José, Armengol Fortí JosepAbstract:[EN] Four vineyards visibly affected by trunk diseases were surveyed at Pruning time in 2012 and 2013 in Spain, to determine whether Pruning tools are capable of spreading grapevine trunk diseases from vine to vine. In each vineyard, Pruning Shears were regularly rinsed with sterile water, collecting liquid samples for analysis. Molecular detection of grapevine fungal trunk pathogens (GFTPs) was performed by nested polymerase chain reaction using specific primers to detect Botryosphaeriaceae spp. Eutypa lata, Cadophora luteo-olivacea, Phaeoacremonium spp., and Phaeomoniella chlamydospora. All of these GFTPs, with the exception of E. lata, were detected in samples from the four vineyards, C. luteo-olivacea and Phaeoacremonium spp. being the most prevalent. Co-occurrence of two, three, or four different GFTPs from the same sample were found, the simultaneous detection of C. luteo-olivacea and Phaeoacremonium spp. being the most prevalent. In addition, fungal isolation from liquid samples in semiselective culture medium for C. luteo-olivacea, Phaeoacremonium spp., and P. chlamydospora was also performed but only C. luteo-olivacea was recovered from samples collected in three of four vineyards evaluated. Pruning Shears artificially infested with suspensions of conidia or mycelial fragments of C. luteo-olivacea, Diplodia seriata, E. lata, Phaeoacremonium aleophilum, and Phaeomoniella chlamydospora were used to prune 1-year-old grapevine cuttings of '110 Richter' rootstock. Successful fungal reisolation from the cuttings 4 months after Pruning confirmed that infested Pruning Shears were able to infect them through Pruning wounds. These results improve knowledge about the epidemiology of GFTPs and demonstrate the potential of inoculum present on Pruning Shears to infect grapevines.This research was financially supported by the Project RTA2010-00009-C03-03 (Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, INIA, Spain) and the European Regional Development Fund (ERDF), and performed within the Programme VLC/Campus, Microcluster IViSoCa (Innovation for a Sustainable Viticulture and Quality)Agustí Brisach, C.; León Santana, M.; García Jiménez, J.; Armengol Fortí, J.
