- Planriz is a fungicide that contains rhizosphere bacteria and biologically active substances secreted by them. The drug is popular for seed treatment before sowing in the ground, as well as for periodic treatments. Bacteria penetrate the soil and colonize plant roots, where they release antibiotics that are effective against fungi. It is a safe fungicide against fruit rot and fungal root diseases.
- Fungicide Bactofit is effective against late blight, powdery mildew, fusarium, root rot, helminthosporium and other diseases. It synthesizes natural antibiotics that inhibit fungal growth, as well as phytohormones to improve the overall health of the plant.
Organic fungicides are safe and can be applied throughout the growing season, including before harvesting.However, they are not very effective and will not help with a significant degree of infection.
Contact fungicides

Herbal fungicides are several groups of drugs that destroy pathogens of fungal diseases. They belong to different classes, which differ in composition and mechanism of action and degree of effectiveness. Natural fungicides for plants, preparations based on beneficial bacteria capable of synthesizing antibiotics, are becoming increasingly popular. However, for the treatment of large areas and agricultural land, systemic chemical fungicides are still preferred due to their high efficiency and low cost.
