The causative agent of the disease late blight, familiar to summer residents, is an obligate fungus.
This means that the methods used to treat plants for other fungal diseases are not suitable for combating this scourge.
The only way that will really help you clean the soil from late blight spores that have entered it is to use Trichoderma.
This organism is capable of leading a parasitic existence on late blight spores: it germinates inside, absorbs their contents and destroys them in the process.
As a parasite on other parasites – this is how one can describe the effect of Trichoderma.
In this regard, in the fall, especially in those places where late blight is especially active (and a tomato greenhouse is just such a place), it is recommended to add Trichoderma.
Since late blight spores can survive in light soils for up to four years, treatments should be carried out regularly.
This will help you to completely clear the soil.
Lastly, Trichoderma can be used in any form, for example, grown on grain.
