Fungicide with living microorganisms, for the treatment of soil fungi, in various rural and greenhouse crops. It is applied preventively to the soil through the drip irrigation system, towards the end of irrigation, with a volume of water of 200 liters / ha, to ensure good distribution of the product around the root system of the plants. Soil temperature during application should be > 12 oC and < 37 oC. The most appropriate temperature for the development of the fungus is 25 – 30 oC.The pH of the soil should >be 2 and < 9. The most suitable pH for the development of the fungus is 4 – 7. Soil moisture and the organic matter content of the soil are key factors for the growth and activation of the fungus. The appropriate soil moisture is 70-80 %. The high content of salts in the soil inhibits the development of the fungus.
