The application of chemicals, such as fungicides for seed treatment, is one of the most
reliable and perhaps most efficient measures for integrated preservation of crops, and its
practicing has become a legal obligation for all seed producers. This investigation was carried
out in the laboratory for seed quality and phytopathology of the Small Grains Research
Center in Kragujevac. The objective was to establish the effect of fungicides on germination
energy and seed germinability (determined after treatments). Two varieties were tested
due to a possibility of specific sensitivities of some varieties, so that the results acquired
on one variety would not necessarily be valid for another one.
Fungicides based on active ingredients from the triasol chemical group had different
effects on the energy of germination of barley seeds. Applying Raxil S040-FS, the average
germination of barley seeds was 79.3% for the variety Record, and 91.3% for the Grand variety.
The variety Record achieved a lower value than the minimum for barley seed germination
(88%) stipulated by the Rules on Seed Quality of Agricultural Crops.
Regardless of barley type, the product Raxil S040-FS showed a statistically significant
effect on the number of atypical seedlings and increase in the number of non-germinated
seeds, compared to the control. Primena hemijskih mera, kao što je tretiranje semena fungicidima, predstavlja jedan od
najpouzdanijih i, možda, najefikasnijih mera integralne zaštite useva, zbog čega je ovo i zakonska
obaveza svih proizvođača semenske robe. Ispitivanja su izvedena u laboratoriji za ispitivanje
kvaliteta semena i fitopatologiju u Centru za strna žita u Kragujevcu. Cilj ispitivanja
je bio da se utvrdi uticaj fungicida na energiju klijanja i klijavost semena koje je određeno
odmah posle tretiranja. U ispitivanju su bile uključene dve sorte, jer postoji mogućnost
postojanja specifične osetljivosti nekih sorata i rezultati dobijeni na jednoj sorti ne moraju
važiti i za druge sorte.
Na energiju klijanja semena ječma utvrđen je različiti uticaj fungicida aktivnih materija iz
hemijske grupe triazola. Primenom preparata Raxil S 040-FS dobijena je prosečna klijavost
semena ječma kod sorte Rekord od 79,3%, a kod sorte Grand 91,3%. Vrednost dobijena kod
sorte Rekord je niža od minimalne propisane vrednosti za klijavost ječma (88%) koju propisuje
Pravilnik o kvalitetu semena poljoprivrednog bilja.
Nezavisno od sorte ječma preparat Raxil S 040-FS je u odnosu na kontrolu pokazao statistički
značajan uticaj na broj atipičnih klijanaca i na povećanje broja neklijalog semena.
