The present invention is related to a method for improving plant growth and reduce the effects of diseases, with environmental friendly techniques. This is a method for controlling or ending diseases and also, to perform a non-stop electromagnetic combine with invaded electrons treatment with its effective methods for soil, plants, trees and their roots region. Furthermore, high voltage electricity can control the borer insect/s, nematodes in plant, tree and in the soil under treatment. Some of the pathogens, nematodes and insect/s in the region influenced by the magnetic field, invaded by squall of electrons, can be decontaminated after the treatment. The exited and invasive electrons pass through the magnetic field region via negative terminal and will be discharged at positive discharge points which located on discharge bar. After receiving the high voltage treatment, the infected plant can be stimulated to regenerate and grow new leaves, shoots, and/or flashes that exhibit little to no symptoms of infection, depending on the voltage applied to the infected plant and the condition of the infected plant.
