Speaking about the phytophthora itself, which affects mainly tomatoes, it should be noted that there can be a lot of reasons for its appearance. This is a fungal disease, so almost all the prerequisites for its appearance are the same as for the usual fungus:

  • insufficient air;
  • high humidity;

Leave to infuse for an hour (a bucket or other container should be covered). Then add 10 ml of iodine and 10 g of boric acid, dilute with water so that it becomes 10 liters of the mixture. All this is left for a day.
