Trichoderma atroviride SC1 prevents Phaeomoniella chlamydospora and Phaeoacremonium aleophilum infection of grapevine plants during the grafting process in nurseries

Evaluation of long‐term protection from nursery to vineyard provided by Trichoderma atroviride SC1 against fungal grapevine trunk pathogens

“…Nursery treatments with T. atroviride SC1 had already been reported as effective to control grapevine plant infection by Pa. chlamydospora and Pm. minimum , fungal species associated with Petri disease, during the grafting process . However, our results also suggest that, in addition to these pathogens, this BCA may be used to control some Botryosphaeria dieback pathogens, such as D. seriata , in the grapevine propagation process in an integrated approach for the management of GTD …”

“…These results reinforce that this BCA, which was isolated from decayed hazelnut wood in northern Italy, is very efficient in the colonization of different plant substrates as already demonstrated by Longa et al . and Pertot et al ., and it also can survive in nurseries during the storage of grafted plants at low temperatures in the period between plant harvest and their sale to the farmers.…”

“…In grapevine, the species T. atroviride strains USPP‐T1 and USPP‐T2, I‐1237, and SC1 have shown good performance in the protection of grapevine against GTDs. Soil applications of T. atroviride T11 + T. asperellum T25, combined with white mustard cover crop residue amendment and chemical fumigation with propamocarb + fosetyl‐Al, were evaluated to reduce black‐foot pathogen infection in grapevine grafted plants, but no added benefit was obtained when biofumigation was used with Trichoderma spp .…”

A critical review of plant protection tools for reducing pesticide use on grapevine and new perspectives for the implementation of IPM in viticulture

“…Recognising the critical importance of these two factors raises the issue of a possible redesign of the entire nursery production process (Gramaje and Armengol, 2011;Gramaje and Di Marco, 2015;Waite et al, 2015). Available tools ready to be applied in the nursery include primarily the use of microbial biofungicides, in particular several Trichoderma species, which have already proved to be efficient against some of the main pathogens associated with GTDs (Fourie and Halleen, 2006;Pertot et al, 2016). In addition, disinfection with hot water treatment has been proposed as a way of reducing infections, albeit with variable results in terms of efficacy and plant quality (Gramaje and Armengol, 2011).…”

“…As a preventive measure in vineyards, protection of pruning wound is an essential step, and biological fungicides (mainly based on strains of Trichoderma spp.) are available (Pertot et al, 2016;Zanzotto and Morroni, 2016). Trials are underway with wound protectants containing synthetic pesticides or physical barriers, which may offer additional tools in the near future (Rolshausen et al, 2010).…”
