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).

Measuring elemental sulfur in grape juice in relation to varietal thiol formation in Sauvignon blanc wines.

Aim: Sauvignon blanc displays a range of styles that can include prominent tropical and passionfruit aromas. Both sensory evaluation and chemical analysis have confirmed the above-average presence of ‘varietal thiols’ in the Sauvignon blanc wines from Marlborough, New Zealand.

La haie bocagère comme critère de zonage à l’échelle parcellaire

In the French AOCs, the production area of ​​the raw material can be subject to plot delimitation based on criteria of physical environment and use. On the other hand, many environmental zonings are developing and the AOCs are called upon include provisions relating to these concerns. Hedges, through their effects on local changes in the regional climate and on functional biodiversity, can impact the functioning of vines and orchards. It is for this reason that their consideration as a delimitation criterion is envisaged.

Vitis v. corvina grapes composition and wine sensory profile as affected by different post harvest withering conditions

Context and purpose of the study – In Valpolicella area (Verona – Italy) Vitis vinifera cv. Corvina is the main wine variety to obtain, after grape withering, Amarone wine: this study was carried out in order to compare two different grape dehydration conditions with the aim of verifying the final composition of Corvina dried grapes and the organoleptic profile of corresponding Amarone wine.
