Descrição da doença
Venturia inaequalis is a phytopathogenic fungus that causes the disease known as apple scab. The fungus can survive on fallen leaves and infected plant remains, especially during winter, in the form of reproductive structures such as ascospores. These ascospores are released in spring and spread through the air to infect new leaves, flowers, and fruits. The fungus develops on leaves, fruits and shoots, forming lesions that can expand rapidly.

Descrição do patógeno
Apple scab produces dark, superficial lesions on leaves, flowers and fruits, which can cause deformation and premature fall of the leaves and fruits. These injuries can also reduce the commercial quality of the crop.
• Dark and superficial lesions on leaves, flowers and fruits.
• Deformations in leaves and fruits.
• Premature fall of leaves and fruits.
• Reduction in the commercial quality of the harvest.

Recomendações
• Use apple varieties resistant or tolerant to Venturia inaequalis.
• Practice proper pruning to improve air circulation and reduce moisture in the foliage.
• Remove and destroy fallen leaves and remains of infected plants to reduce the inoculum.
• Apply specific fungicides following local recommendations, especially during spring.
• Disinfect pruning tools and equipment to prevent the spread of the fungus.
• Carry out regular monitoring to detect and eliminate infected parts.

There are no treatments for this disease. Treatments are directed at the insect vectors that transmit it. See insect treatments.
RECOMMANDATIONS
- Check the back of the leaves frequently, especially in dry weather.
- Spray water on the leaves to increase humidity and prevent them from settling.
- Keep plants healthy with good watering and adequate light.
- If you see cobwebs or damage, clean the leaves with a damp cloth or pressurized water.
- Use potassium soap or neem oil every few days until they disappear.
