Abstract

Sclerotinia sclerotiorum (Ascomycota) je vrlo uspješan biljni patogen, širok raspon domaćina gljive važan za kontrolu bolesti u poljoprivrednim usjevima. Značajan je patogen salate i uzročnik bijele truleži salate. Za potrebe biološkog suzbijanja razvijeni brojni biofungicidi koji se baziraju na antagonističkim Trichoderma vrstama. U radu je istraživana antagonistička sposobnost autohtonog izolata Trichoderma atroviride STP8 na fitopatogenu gljivu S. sclerotiorum. Istraživanje je provedeno umjetnim infekcija salate sa sklerocijima Sclerotinia sclerotiorum. Izolat STP8 signifikantno je inhibirao rast i razvoj patogena, kvaliteta praćenih parametara nadzemnog dijela biljaka bila je signifikantno povećana u varijanti pokusa s izolatom STP8, te je izolat STP8 potvrđen kao mikoparazit sklerocija S. sclerotiorum.

Abstract (english)

Sclerotinia sclerotiorum (Ascomycota) is a significant plant pathogen, wide range of hosts is important for disease control in agricultural crops. It's important lettuce pathogen and the cause of white mould. Numerous biofungicides based on antagonistic Trichoderma species have been developed for the purpose of biological control. The antagonistic ability of the autochthonous isolate of T. atroviride STP8 on the phytopathogenic fungus S. sclerotiorum was investigated. The research was conducted by artificially infecting lettuce with sclerotia. The STP8 isolate significantly inhibited the growth and development of the pathogen, in the experiment with the STP8 isolate the quality of the monitored parameters of the aerial part of the plants was significantly increased and the STP8 isolate was confirmed as a mycoparasite of S. sclerotiorum.
