Reviews of summer residents
Alena, 35, Yekaterinburg At one time, anthracnose became a regular guest on my site. To save the grapes, I decided to conduct a spring prevention of the disease. I bought the fungicide Poliram in a plastic bag weighing 20 g and processed the grapevine according to the attached instructions. The result did not impress me, maybe I did something wrong, or the drug was expired. But anthracnose reappeared, and I had to purchase another product. Sergey, 50, IvanovoUsed the drug Poliram to protect the orchard from fungal diseases. I did not like the fact that this requires about 4 sprays, the procedure takes a lot of time. But it was worth it, apples and pears delight juicy fruits and bright greens. Now I will apply a fungicide every year.
