Abstract

Esca je bolezenski kompleks, saj je zanjo značilno, da pride do sočasnega pojava več bolezenskih znamenj oziroma bolezni. Običajno jo povzročajo tri glive, te so Phaeoacremonium aleophilum, Phaeomoniella chlamydospora in Fomitiporia mediterranea. Bolezenski kompleks združuje naslednje bolezni: rjava progavost lesa, Petri-jeva bolezen, bela trohnoba, mlada esca in prava esca. Ukrepe za zatiranje esca-e se delimo na preventivne in kurativne. Med preventivne ukrepe uvrščamo ustrezen čas in način rezi vinske trte ter zaščita ran po rezi, termoterapija, kemoterapija itn. Med kurativne ukrepe pa spadajo predvsem postopki, ki temeljijo na t.i. sanacijski kirurgiji, pri kateri se iz trte odstranjuje oboleli les. V zadnjem obdobju se kot alternativa vse bolj uveljavlja uporaba mikoparazitskih gliv iz rodu Trichoderma kot samostojni ukrep ali v kombinaciji s katerim od prej naštetih. V nalogi smo predstavili esco kot bolezenski kompleks, proučili zgodovino njenega raziskovanja ter na podlagi literature definirali patogene, ki jo povzročajo, značilna bolezenska znamenja, ter opredelili in oceniti ukrepe zoper esco.

Secondary title: ESCA disease complex and measures to reduce infections on grapevine (Vitis vinifera L.)
Secondary abstract: Esca is a disease complex because one of its features is the fact that it is comprised of multiple diseases. It begins with three fungal species Phaeoacremonium aleophilum, Phaeomoniella chlamydospora in Fomitiporia mediterranea. Disease complex is comprised of the following diseases: brown streaking disease, Petri disease, white rot, young esca and esca proper. Countermeasures against esca are divided into preventive and curative processes. Preventive ones being time of pruning and pruning technique, wound protection, chemotherapy and thermotherapy. Curative measures are mostly techniques where the diseased wood is removed in some way. Lately there has been a rise in the use of mycoparasitic fungi Trichoderma spp. as a standalone process or in combination with any of the aforementioned ones. In the assignment, esca has been presented as a disease complex, study of its research, defining the pathogens that cause esca and its symptoms, define and evaluate countermeasures against it.
