Tomatoes are high in serotonin, so they are able to elevate mood.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;
- any failure to maintain the desired temperature (mostly cold).
Important! Phytophthora is preserved mainly in potatoes, so initially it can appear on its leaves, and a week later it spreads to tomatoes.
Use in the greenhouse
Based on the considered causes of the manifestation of the disease, it can be determined that the fungus will feel great in the greenhouse, since air practically does not penetrate there, and the condensate on the greenhouse walls provides optimum humidity.
In order for the phytophthora not to manifest itself also from the cold, one must be attentive to the site at the end of summer, when the nights become rather cool. We will understand how to properly use iodine in the greenhouse.

The first feeding with solutions needs to be done when a second pair of leaves has appeared in a tomato. The following solution is applied to the wet soil: a drop of iodine in 3 liters of water.
Further top dressing is done when the brushes are tied to the tomatoes. At the same time in a solution of 10 liters of water should be 3 drops of iodine. Under each bush you need to make a liter of dressing.

Next, you can feed the tomatoes when they bear fruit. To do this, 5 liters of hot water need to sift the ash (about 3 liters). 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.
Fertilize the mixture diluted in warm water: 1 liter of the mixture per 10 l of water.
