ABSTRACT:
It is a known problem that cultivation products such as bulbous plants, for instance lilies or also potatoes, are often damaged by micro-organisms such as nematodes, insects, fungi, bacteria and viruses. Such micro-organisms are often to be found in cultivated soil or other cultivation media and plant tissues such as that of roots, bulbs and tubers and other plant parts, and affect this tissue when the cultivation products are re-planted.
It is an object of the invention to provide a method and a device using which cultivation products or cultivation media can be effectively treated such that damage to cultivation products is effectively prevented, whereby the effective yield of these cultivation products can be increased considerably.
In respect of the above the invention provides a method for treating cultivation products or a cultivation medium, for instance cultivated soil or a growth substrate, against micro-organisms, for instance nematodes, according to which method the cultivation products for treating are placed in an electric and/or a magnetic field and held therein for a certain minimum time.
