Fungicides, or, translated from Latin, substances that kill fungi, help fight fungal infections of plants. The mechanism of their action is aimed at suppressing the vital processes of pathogenic microorganisms. Modern plant growers have access to drugs of various safety classes. Biological fungicide "Alirin" is one of the most effective and safe plant protection products based on Bacillus subtilis.
Composition and principle of action
"Alirin-B" refers to plant protection products against fungal infections.This is not a chemical substance, but a biological drug. It is much safer for humans, other animals, and insects. The preparation contains bacteria Bacillus subtilis strain 10-VIZR. These are the most productive microorganisms that help in the fight against pathogens of fungal diseases of garden and garden plants.
Important! When the temperature drops to 0 degrees, bacteria form spores and in this state tolerate unfavorable external factors well.
The bacterial culture of Bacillus subtilis in the preparation is represented by living encysted individuals. When conditions improve, they emerge from the cysts and begin to germinate. As microorganisms grow, they begin to produce antibiotics.
Purpose and properties
Biological fungicide "Alirin-B" is intended to protect the following plants from diseases:
- Flower crops, both indoor and outdoor. Effective against spotting and root rot.
- Potatoes. Helps defeat late blight and rhizoctonia. It is used for spraying ground parts and treating planting tubers.
- Indoor and open ground tomatoes, other nightshade crops. Protects them from root rot, Alternaria, and late blight.
- White cabbage. Copes with blackleg and bacteriosis.
Can also be used on other crops:
- sugar beets;
- cucumbers;
- cereals;
- grapes;
- various berry bushes.
The drug can be used to treat seed and planting material, soil in greenhouses, greenhouses and open beds, and above-ground parts of plants. The properties of the fungicide are based on the fact that the bacteria Bacillus subtilis produce antibiotics that are antagonists for pathogenic fungi.
They not only cope with them and have a detrimental effect on their colonies, but also help plants develop immune defenses against them.
It also promotes:
- restoration of microflora in the soil;
- an increase of approximately 1/3 in the amount of vitamin C and proteins in fruits and seeds;
- reducing nitrates in products by at least 25%.

Reviews
The best characteristic of the Alirin-B fungicide is consumer reviews.
N.H., Kirov, Russian Federation, amateur flower grower: “During the lack of heating and in a rather cold spring, indoor flowers fell ill with powdery mildew. The disease very quickly affected almost all potted specimens. In a specialized store, the seller recommended Alirin-B. I dissolved 1 tablet in 0.5 liters of water. I poured the working solution into a regular sprayer. The result was visible after the first treatment. A week later I repeated the flower treatment. Signs of the disease disappeared. The third treatment was preventive in nature. The advantages of the product include its safety and non-toxicity. Disadvantage: poor solubility. Overall score 4 points on a 5-point system.” Roman M., Vsevolozhsk, Russian Federation, summer resident: “I grow a variety of crops at my summer cottage. There is a small greenhouse in which I get the earliest harvest of cucumbers. Despite care, fertilization, and timely watering, I noticed that the leaves on the plants began to turn yellow. The disease began at the tops of the plants and spread to the stems and roots. I assumed it was a fungal infection. The store offered Alirin-B. Signs of the disease disappeared after two treatments. Considering its low cost and safety, the drug is very convenient for gardeners, summer residents, and greenhouse owners.”
