Nematodes are widespread organisms that exhibit remarkable ubiquity, biodiversity, and adaptability in diverse ecosystems. While most nematodes are beneficial, there are also some parasitic species that have harmful effects. Among these plant-parasitic nematodes is the species Xiphinema index. It primarily colonizes the root environment of grapevines (Vitis vinifera L.), as these vines serve as its primary host. Although the nematode's direct effects on roots are not particularly problematic, it poses a significant threat to grapevine because it can transmit and introduce Grapevine Fanleaf Virus (GFLV), a member of the genus Nepovirus. Infection with GFLV can result in yield losses of over 80 %. Therefore, it is imperative to take preventive measures to contain the uncontrolled spread of nematodes and the resulting infections in vineyards. In addition to transmission through planting material, agricultural machinery and implements in vineyards are also important vectors. Traditional chemical methods of controlling X. index have proven ineffective due to the nematodes' resilience and widespread distribution in the soil. Future efforts should therefore focus on pursuing alternative, more effective approaches. In addition to intercropping, the efficacy of bacterial and fungal preparations has also been tested and offers great potential for further research. [ABSTRACT FROM AUTHOR]
Ogorčice so organizmi, ki jih zaradi njihove številčnosti, raznolikosti in prilagodljivosti najdemo praktično povsod. Medtem ko je večina ogorčic koristnih, pa poznamo tudi take, ki s svojim parazitiranjem povzročajo škodo. Med škodljive ogorčice uvrščamo tudi rastlinsko-parazitsko vrsto Xiphinema index. Najdemo jo lahko v bližini korenin žlahtne vinske trte (Vitis vinifera L.), saj je prav ta njena glavna gostiteljica. Ogorčica ni tako problematična z vidika neposrednega napada korenin, ampak vinski trti predstavlja grožnjo zaradi prenosa in vnosa virusa pahljačavosti listov vinske trte (GFLV) iz rodu Nepovirus. Virus namreč na vinski trti povzroči bolezen kužne izrojenosti vinske trte, kar vodi v ekonomsko nekonkurenčnost vinogradov. Okužba lahko privede tudi do več kot 80 % izpada pridelka. V izogib nenadzorovanemu širjenju ogorčic in posledično okužbam v vinogradih je pomembna preventiva, saj poleg prenosa s sadilnim materialom, pomembnega prenašalca predstavljata tudi kmetijska mehanizacija in fizični prenos z orodjem. Ker se je kemično zatiranje ogorčice X. index zaradi njene trdoživosti in razporeditve v tleh izkazalo za neučinkovito, je potrebno v prihodnje stremeti k alternativnim in predvsem učinkovitejšim pristopom. Poleg vmesnih posevkov so preverjali delovanje pripravkov na podlagi nekaterih bakterij in gliv, ki predstavljajo velik potencial za nadaljnja raziskovanja. [ABSTRACT FROM AUTHOR]
