Preliminary Study of Control and Biochemical Characteristics of Giant Hogweed (Heracleum sosnowskyi Manden.) Treated with Microwaves

There is an urgent need to develop new compensatory and human-safe methods for controlling invasive Heracleum species. This research aimed determine the effectiveness of H. sosnowskyi control under microwave radiation biochemical changes in tissues sap after irradiation. In field experiments southern Poland, plants were cut irradiated with a device generating electromagnetic waves (2.45 GHz, 32.8 kW/m2). The efficacy rosette phase 5, 10, or 15 min was 20%, 100%, respectively. flowering 7.5 66% 100%. metabolomic analysis showed significant changes, mainly content composition proteins sugars. tissues, treatments resulted protein denaturation metabolism amino acids glyoxylate galactose pathways. rich sugars, glutamic acid, glutamine, homoserine, serine, methionine. More metabolite levels observed min. conclusion, longer times, e.g., 10 min, efficiently controls it.
