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


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).

Significance of factors making Riesling an iconic grape variety

Riesling is the iconic grape variety of Germany and accounts for 23% of the German viticulture acreage, which comprises 45% of the worldwide Riesling plantings. Riesling wines offer a wide array of styles from crisp sparkling wines to highly concentrated and sweet Trockenbeerenauslese or Icewines. However, its thin berry skin makes Riesling more vulnerable to detrimental environmental threats than other white wine varieties.

Winemaking techniques and wine tasting methods at the end of the Middle Ages

Les pratiques de vinification et de dégustation du vin sont souvent perçues, à travers un discours marketing très puissant, sous l’angle d’une tradition millénaire qui perdure depuis le Moyen Âge. En Bourgogne, il est courant de rattacher les racines de ces pratiques à l’activité des institutions ecclésiastiques qui possédaient d
