Use of microorganisms in the disinfection/protection of organic rooted-cuttings from wood pathogens

Abstract

One of the major problems affecting the viticulture sector is the quantity of plant protection products (especially copper) used to control the main foliar diseases of the vine. The Life Green Grapes project enter in the production context with the aim of reducing the use of fungicides throughout the production cycle, starting from mother plants protection in the field up to the production of wine and table grapes.

The process goes through the nursery sector where it aims to improve both the phytosanitary state of the rooted-cuttings, reducing the endophytic presence of potentially pathogenic wood fungi, and the qualitative aspect of the nursery material, through the application of a consortium of microorganisms that increase the microbial biodiversity associated with the rhizosphere.

At the “Vivaio Moroni”, partner of the project, the propagation material was treated following three different application protocols: 1) Corporate Bio; 2) Trichoderma+Mycorrhiza; 3) Trichoderma.

To evaluate the most suitable time for the application of the products, treatments were carried out at different stages of the production process: 1) before storage in the fridge at 4⁰C; 2) before delivery to the vine farm; 3) just before planting.

The analyzes carried out showed a greater root mass in the proximal area in all the treatments with Trichoderma+mycorrhiza and allowed to quantify the presence of the applied microorganisms; they showed the effects on the vegetative state (statistically significant differences between the control and the treatments); and furthermore highlighted the tendency to reduce wood pathogens in both treatments (Trichoderma only and with Trichoderma+Mycorrhizae).

Effect of irrigation in cover cropping vineyards

Cover cropping in vineyard is a sustainable and alternative soil management system to conventional tillage that is gaining more and more importance among winegrowers and is being promoted, among other organizations, by the European Union through the eco-schemes of the Common Agricultural Policy.
However, the use of cover crops in Mediterranean viticultural environments is conditioned, to a large extent, by the availability of irrigation water which, in a context of global warming like the one we are experiencing, must be adjusted to savings strategies, supplying to the vine only what it needs in each moment.

Cumulative effect of deficit irrigation and salinity on vine responses

Climate change is increasing water needs in most of the wine growing regions while reducing the availability and quality of water resources for irrigation. In this context, the sustainability of Mediterranean viticulture depends on grapevine responses to the combinations of water and salt stress. With this aim, this work studies the effects of deficit irrigation and salinity on the physiology of the Tempranillo cultivar (Vitis vinifera L.) grafted onto a drought and salinity tolerant rootstock (1103 Paulsen).

Low and zero alcohol “wines”: impact of different dealcoholization processes on phenol profile and health benefits

Consumers’ demand for non-alcoholic wine has notably increased in the last years: this trend is a consequence of a growing interest in more healthy habits, and as a response to higher alcohol levels in wine due to climate change. In addition, drinking limitations due to physiological/pathological conditions (e.g., pregnancy, diabetes, hepatic disorders), driving regulations, ethical/religious considerations, and high import taxes on alcoholic beverages have positively influenced this marked (us$ 1.6 billion in 2021). International organisation of vine and wine (OIV) established that alcohol content defining wines must not be less than 8.5% vol, (OIV, 2017).
