How to treat tomatoes from hytophor?

Signs of late blight

Phytophthora infestans – the fungus that causes late blight, multiplies quickly and reduces yields by up to 50%.

Symptoms of phytophthora are brown spots with plaque on leaves, stems and fruits, after which the affected cells begin to die, and diseased plants become unfit for consumption.

Favorable weather for the development of the disease – humidity of at least 80%, retention of water in the garden after rainfall, a sharp drop in temperature after which it remains at the level of 20°C, morning dew. Spores are carried by the root system and by wind.

Phytophthora prevention

Preventive measures will help to prevent the disease:

  • separate planting of tomatoes and potatoes;
  • maintaining the optimal distance between plants (about 50 cm);
  • pinching the lower leaves and stepsons to ensure ventilation;
  • cleaning weeds and dry vegetation;
  • watering only under the root;
  • mulching;
  • treatment with prophylactic drugs.
