Most Common Pathologies in Autumn Plants

Plants in autumn are often subject to various diseases, including fungal diseases and pest infestations . Recognising the symptoms and intervening promptly is essential to keep the garden healthy.

Fungal diseases

The humidity typical of autumn favors the appearance of fungal diseases. Here are the main ones and how to treat them:

1 - Powdery mildew: Characterized by a white patina on the leaves.

How to treat powdery mildew on autumn plants

Powdery mildew, also known as "white mildew," is one of the most common fungal diseases that affect plants in the garden and vegetable garden. It manifests itself as a whitish or grayish patina on the leaves, stems and, in some cases, fruits. An effective solution to combat this disease is the use of Zolvis, a sulfur-based fungicide.

Why use Zolvis to combat powdery mildew?

Zolvis is a micronized sulfur-based product that acts by contact, inhibiting the growth of the fungus responsible for powdery mildew. It is effective and safe for a wide variety of crops, both in the open field and in greenhouses.

Active ingredient: Micronized pure sulfur.

Mode of action: It works by blocking spore germination and stopping the development of fungal mycelium.

Doses and methods of application of Zolvis

Doses:

300-500 g per 100 litres of water for horticultural, fruit and ornamental plants.
2-5 kg per hectare, depending on the cultivation density and the severity of the infestation.

How to use:

Prepare a solution with water, making sure the product is well mixed.
Spray the mixture evenly on all surfaces of the plant, including the underside of the leaves.
Repeat the treatment every 7-10 days in case of climatic conditions favorable to the development of powdery mildew (heat and humidity).

When to use Zolvis?

Prevention: Apply Zolvis at the beginning of the season when the climatic conditions are favorable for powdery mildew (temperature between 15°C and 25°C).
Treatment: Intervene as soon as you notice the first symptoms, such as whitish or dusty spots on the leaves or shoots.

Useful Tips

Avoid application on very hot days or with temperatures above 30°C to prevent phytotoxicity.

Do not use Zolvis in combination with mineral oils or copper-containing products, to avoid adverse chemical reactions.

Rinse the equipment well after use to avoid residue.

2 - Downy mildew: It manifests itself with yellowish spots on the leaves and whitish mold on the underside.

How to fight downy mildew on autumn plants

Blight is one of the most feared fungal diseases in autumn, caused by pathogens such as Phytophthora and Peronospora spp., which thrive in conditions of high humidity and moderate temperatures. This disease manifests itself with yellow or brown spots on the leaves, necrosis on the stems and, in severe cases, the decay of the entire plant.

Kaolin: mechanical protection against downy mildew

Kaolin is a natural mineral powder that creates a protective barrier on the surface of the plant, preventing the fungus from attacking plant tissues.

Doses: 2-3 kg per 100 liters of water.

How to apply:

Mix the product in water until a homogeneous solution is obtained.
Spray evenly on leaves and stems, also covering the underside of the leaves.

Useful tips: Apply in prevention, especially after periods of rain, to reduce surface moisture on plants.

Zeolite: moisture-absorbing and natural reinforcement

Zeolite is a volcanic silicate that absorbs excess moisture, creating an unfavorable environment for the fungus to develop. In addition, it improves the resistance of plants to downy mildew attacks.

Doses: 2-4 kg per 100 liters of water.

How to apply:

Mix in water and apply to leaves, stems and surrounding soil.
Repeat the application every 10-15 days during the fall.

Useful tips: Ideal for horticultural and fruit crops, especially in areas subject to high humidity.

Cupravit: copper for the direct control of downy mildew

Cupravit (license required) is a copper-based fungicide, effective both in prevention and in curative treatment against downy mildew. Copper is a key element in the management of this disease due to its direct action on the pathogen.

Doses: 250-300 g per 100 liters of water for horticultural and ornamental crops; 2-3 kg per hectare in open field.

How to apply:

Prepare a solution with the recommended dose and spray evenly over the entire plant.
Make sure that the treatment also covers the new shoots and the underside of the leaves.

Useful tips: Use alternately with natural products such as Kaolin or Zeolite to reduce the risk of copper accumulation in the soil.
