Abstract

Od patogena koji ugrožavaju proizvodnju voćnih vrsta, uzročnik bakterioznog paleža, bakterija Erwinia amylovora, svakako pripada u najznačajnije na svjetskoj razini. Ova je bolest prisutna u četrdesetak država diljem svijeta. Kao najugroženiji domaćini bakterije E. amylovora, većinom se navode kruška i dunja, dok se jabuka smatra manje osjetljivom na ovu zarazu. Obzirom na zastupljenost domaćina, bakteriozni palež je najdestruktivniji za jabuku i krušku. U Hrvatskoj su karakteristični simptomi... More koji podsjećaju na palež (engl. Fire blight) uočeni prije više od 25 godina, u okolici Osijeka. Premda poduzeta, eradikacija nije bila potpuna te se bakteriozni palež do sada proširio i bolest je prisutna u većem dijelu kontinentalne Hrvatske. Bolesna stabla moguće je ozdraviti jedino rezidbom, dok najbolje rezultate u sprječavanju nastanka novih zaraza postižu preventivne mjere intergirane zaštite bilja. Nekoliko raspoloživih registriranih pripravaka za kemijsko preventivno suzbijanje potrebno je pravovremeno primjenjivati sukladno preporukama prognoznih modela. Ovim radom se u uvjetima in vitro testiralo antibakterijsko djelovanje vodenih otopina bakrovog sulfat pentahidrata na izolat bakterije Erwinia amylovora iz kruške s lokacije Kutjevo. Rezultati rada idu u prilog korištenju slabijih otopina ovog spoja za potrebe preventivnog suzbijanja uzročnika bakterioznog paleža u vremenu prije nastanka novih zaraza. Less

Abstract (english)

Among pathogens that endanger the fruit production, the bacterium Erwinia amylovora causing Fire blight certainly belongs to the list ofthe most significant on the world level. This disease is present in about forty countries around the world. As the most endangered hosts of E. amylovora, commonly pear and quince are referred, while apple is considered less susceptible to infection. Due to the host's presence, bacteriosis is the most destructive on apples and pears. In Croatia, there are... More typical symptoms of Fire blight observed over 25 years ago, nearthe town of Osijek. Although undertaken, the eradication was not complete and the bacterium has so far spread and the disease is presentin most of continental Croatia. The sick tree can only be cured by pruning, while the best results in preventing the emergence of new infections are achieved through preventive measures of integrated plant protection. There are few available plant protection product sintended for chemical preventive control but they should be timely applied in accordance with the recommendations of the forecast models. By this work in vitro antibacterial activity of copper sulphate pentahydrat eaqueous solutions to the isolate of the Erwinia amylovora from pear from Kutjevo wastested. The results of the study are in favor of the use of weaker solutions of this compound for the prevention of new infections. Less
