DESCRIPTION
WHO CAUSES IT?
Mycoses in the vine are caused by several species of phytopathogenic fungi that affect different parts of the plant, mainly roots, stems and leaves. These fungi are microscopic organisms that spread through spores, which are dispersed by wind, water or contact with infected tools. Once the spores find a favorable environment on the vine, they germinate and develop filaments called hyphae, which penetrate the plant tissues and spread, consuming nutrients and weakening the vine's natural defenses. Fungi survive in soil or plant remains, entering a state of rest during adverse conditions and reactivating when environmental conditions, such as temperature and humidity, are optimal for their development. In certain cases, spores can also remain attached to plant surfaces during the winter, waiting for the right conditions to initiate a new infection.
SYMPTOMS
Mycoses in the vine can cause significant weakening of the plant, affecting its ability to grow and produce fruit optimally. These diseases manifest mainly in the roots, stems and leaves, causing a progressive loss of vigor and, in severe cases, the death of the plant. The infection affects the vascular system of the vine, making it difficult to absorb water and nutrients, leading to generalized decay.
- Discoloration and necrosis in leaves and stems.
- Premature defoliation.
- Necrotic lesions on the stems and roots.
- Delay in plant growth.
- Regressive death of branches.
- Reduction in grape production.

- Carry out periodic monitoring of the vines to detect the early presence of fungi and act quickly with control measures.
- Use vine varieties more resistant to fungal diseases to reduce the incidence of mycoses in vineyards.
- Maintain good drainage in the soil to avoid conditions of excess humidity that favor the growth of fungi.
- Regularly disinfect pruning and harvesting tools to prevent the spread of fungal spores between plants.
- Remove and eliminate the remains of infected plants to reduce the source of inoculum in the vineyard.
- Apply preventive treatments with fungicides in the most vulnerable phases of vine development, such as budding and initial growth.
- Promote adequate ventilation in the vineyard to reduce humidity in the foliage and make it difficult for fungi to establish.
