Alirin-B, WP for industrial greenhouses
Biological fungicide for protection against pathogens causing root rot and leaf infections.
Alirin-B, WP is a biological fungicide based on the bacterium Bacillus subtilis.
Developed to protect tomatoes, cucumbers and other protected ground crops from pathogens:
root rot and wilting
late blight
ascochyta blight
powdery mildew
alternaria blight
anthracnose
gray rot
Composition of the drug:
Preparation form: wettable powder - SP.
Hazard class: 4 (low-hazard drug), safe for animals and bees.
Shelf life and storage conditions: the drug is stored in the original packaging in dry rooms, protected from direct sunlight at temperatures from -30 °C to +30 °C for 3 years. After opening the package, use the drug within 3 months. Use the working solution within 24 hours of preparation.
Compatibility with chemical pesticides: Compatible with microbiological plant protection products, growth regulators, chemical fungicides, and insecticides. When preparing the working solution, chemical pesticides are added first, stirring constantly, then the biological product is added. Incompatible with Fitolavin and other bactericides.
Compatibility with agrochemicals: The concentration of agrochemical salts in the working solution should not exceed 2%.

Mechanism of Action
Bacillus subtilis bacteria cells inhibit the growth and development of phytopathogenic fungi, which cause diseases, through antagonism (competition) and metabolites (cell secretions)—complexes of antibiotics and enzymes. When the product comes into contact with phytopathogens, the fungal cells are destroyed. Soil and plants are cleared of infection, and the concentration of phytopathogens is sharply reduced.
Period of Protective Action
The duration of the protective action of the drug on the surface of plants (leaves, stems, flowers) is 7-20 days with a single application due to the protective barrier of beneficial microflora. The duration of protection of the root system of plants from soil infection is 2 months.
