The technique of cow-parsnip (Heracleum) controlling is proposed, consisting of combined method application, characterised by use of technical salt, by which the weed plants are treated twice a year (in spring and on July or on August) in two consecutive years. At that the salt treatment is combined with the herb mechanical mowing or cutting. The treatment can be done with rock salt normally used as a component of the mixture, strewed on the roads in winter season against skidding.
