Reviews about Alirin B

Nikolay Alekseev, 44 years old, Irkutsk

This is not the first time I have used Alirin B. For spraying, be sure to add liquid soap. In case of severe infection, you have to additionally use other means, but with regular use of "Alirin", the effect is good.

Anna Martsinovskaya, 38 years old, Azov

For a long time I could not grow daffodils on my site. A friend advised "Alirin B". In the fall, they processed the beds, then in the spring, before planting. For the first time in 5 years, daffodils bloomed, no powdery mildew and rot. I am happy, this year I will try on potatoes and tomatoes.

Alisa Zaitseva, 27 years old, Astrakhan

I love house plants, especially violets. I even sell young sprouts. The last 5 months have been tortured by powdery mildew. Alirin B helped. I watered my violets with it, and a month later the situation began to improve. I am satisfied with the effectiveness of the product, especially for such a ridiculous price.
