Reviews about the drug Dnok

Sergey Smilyakov, 45 years old, Bryansk
I have been familiar with the fungicide "Dnok" for about 10 years, since my professional activity is associated with farms specializing in the cultivation of fruit trees and berry bushes.This agent is really effective against a complex of pests and fungal diseases, but its use is associated with certain risks, since the fungicide is characterized by an increased level of toxicity. Therefore, using it privately is not entirely justified.
Oksana Kozakovskaya, 52 years old, Samara
I learned about Dnok from my friend, who grows apple and pear trees on a professional scale. Indeed, he confirmed the effectiveness of this agent against a complex of fungal diseases and hibernating pests on these crops. But at the same time, I warned against using it on my personal plot, since use near residential buildings at a distance of closer than 1 km is prohibited. Therefore, I have no personal experience of using the Dnok fungicide, since all the shrubs and trees are planted near the house.
