About the book: 2017 / Controlling pests and diseases with the help of chemistry is the last thing, says Nikolay Kurdyumov. After all, the gardener’s goal is not a sterile plant, but one that is healthy enough and capable of producing a normal harvest. Nature itself copes with this task perfectly well, if you do not interfere with it, but help it with its own methods. The author will tell you how to do this in this book. The book was also published under the title “The health of the garden and garden without any poison.”».
