Mendoza’s wine region is bracing for a challenging season as growers prepare for the aftermath of the recent harvest amidst unusually persistent rainfall. Recognizing the potential for increased disease pressure and nutrient imbalances in vineyards, the Instituto Nacional de Tecnología Agropecuaria (INTA) Mendoza is hosting a free workshop on April 1st to equip viticulturists with the latest strategies for post-harvest vine health. This timely event addresses a critical need for proactive vineyard management in the face of changing climatic conditions, focusing on post-harvest disease management and fertilization.
The workshop, titled “Enfermedades y fertilización post cosecha; estrategias en un contexto de lluvias” (Diseases and post-harvest fertilization; strategies in a rainy context), comes at a pivotal moment. With the vendimia – the grape harvest – nearing its end, attention is shifting to the crucial period of vine recovery and preparation for the next growing cycle. The abundance of rainfall presents a unique set of challenges, increasing the risk of fungal diseases and potentially leaching essential nutrients from the soil. Effective management now will be key to ensuring healthy vines and a strong yield in the coming years.
Collaboration for Vineyard Resilience
The initiative is a collaborative effort between INTA EEA Mendoza, the Corporación Vitivinícola Argentina (COVIAR) through its CDV Zona Norte, and the Municipality of Luján de Cuyo. This partnership underscores the importance of a unified approach to supporting the region’s vital wine industry. COVIAR, a key organization in Argentina’s wine sector, works to promote and defend the interests of the vitivinicultural industry, while the Municipality of Luján de Cuyo, a prominent wine-producing area, brings local expertise and resources to the table.
The workshop will be held at the Rubén Oliva Auditorium at INTA EEA Mendoza (Acceso: Aráoz y Acceso Sur, Luján de Cuyo) from 9:00 AM to 12:30 PM on Wednesday, April 1st. Leading the session will be INTA researchers Fernanda Arias and Rodrigo Espíndola, both specialists in viticulture and plant pathology. Participants will receive a certificate of attendance upon completion of the workshop.
Key Topics to be Addressed
The workshop agenda focuses on providing practical, actionable insights for vineyard managers. The session will cover several key areas, beginning with a review of the most relevant aspects of the recently completed season and an analysis of the overall crop cycle. A significant portion of the workshop will be dedicated to strategies for managing diseases in wet conditions, a particularly pressing concern given the current weather patterns. Understanding the specific fungal and bacterial threats that thrive in humid environments, and implementing preventative measures, will be central to the discussion.
Beyond disease control, the workshop will also address the critical topic of fertilization and nutrient reserves for 2027. Maintaining optimal soil health and ensuring vines have adequate access to essential nutrients is crucial for long-term productivity. The presenters will discuss best practices for assessing nutrient levels, tailoring fertilization programs to specific vineyard needs, and mitigating the risk of nutrient loss due to excessive rainfall. Specific topics include:
- Aspectos más relevantes de la temporada y desarrollo del ciclo productivo (Most relevant aspects of the season and crop cycle development).
- ¿Cómo manejar las enfermedades en un contexto de lluvias? (How to manage diseases in a rainy context?).
- Fertilización y reservas 2027 (Fertilization and reserves for 2027).
Practical Application: Vineyard Visit
To complement the theoretical presentations, the workshop will include a practical component: a visit to a local vineyard. This hands-on experience will allow participants to observe firsthand the assessment of vine health and nutritional status in a real-world setting. The vineyard visit will provide an opportunity to apply the concepts discussed during the workshop and to receive personalized guidance from the INTA researchers. This practical element aims to bridge the gap between research and implementation, ensuring that growers can effectively translate knowledge into action.
Registration for the workshop is free but required. Interested individuals can register via this online form. For further information, contact +54 9 11 6056 6027.
The challenges posed by increased rainfall are a reminder of the growing impact of climate change on viticulture. Proactive adaptation strategies, such as those being promoted by INTA and its partners, are essential for ensuring the long-term sustainability of Argentina’s renowned wine industry. The next key date for those interested in staying informed is April 1st, the date of the workshop itself, where attendees will gain valuable tools for navigating the current conditions and preparing for the future.
