Abstract (croatian)

Negativni ekološki i ekonomski učinci pesticida rastu s njihovom prekomjernom primjenom, što je posljedica pogrešne procjene jačine zaraze biljaka. Pogrešna procjena dovodi do provođenja neadekvatnih metoda suzbijanja biljnih patogena i aplikacije prekomjernih doza pesticida u poljoprivrednoj praksi. U svrhu održive zaštite bilja, objektivna i ispravna procjena jačine zaraze biljaka te donošenje odluke o suzbijanju patogena, dugoročno se smatra isplativom metodom. Osim toga, pouzdane procjene jačine zaraze važne su i za predviđanje gubitka prinosa, oplemenjivanje biljaka, praćenje patogena i razvoja otpornosti na pesticide. Suvremene digitalne tehnike preteča su klasičnim tehnikama, kao što su vizualni pregledi koji koriste ljestvice (skale) s određenim numeričkim rasponom. Digitalne tehnike za kvantifikaciju bolesti na biljkama koriste digitalne slike poput fotografija, sken-slika i hiperspektralnih slika, međutim takva procjena ovisi o kvaliteti i karakteristikama slike koja se analizira. Napretkom tehnologije razvijeni su računalni programi (software), a u novije vrijeme i aplikacije za pametne mobitele za brže i preciznije određivanje jačine zaraze biljaka. Aplikacija Leaf Doctor inovativna je poluautomatska tehnika čija primjena reducira vrijeme i napor uložen u procjenu jačine zaraze u terenskim istraživanjima. Ovim preglednim radom predstavit će se poznate karakteristike digitalnih tehnika za procjenu jačine zaraze biljnih bolesti te navesti kriteriji za preciznu kvantifikaciju simptoma na temelju digitalnih slika. Usporedbom računalnog programa (ImageJ) i mobilne aplikacije (Leaf Doctor) s klasičnim pristupom (vizualnim pregledom biljaka), stiče se uvid u mogućnosti bržeg, jednostavnijeg i preciznijeg određivanja stupnja bolesti biljaka, što je važno u fitopatološkim istraživanjima te dugoročno isplativo za biljnu proizvodnju.

Abstract (english)

With the development of technology in phytopathology, digital techniques for assessing the plant disease severity are replacing insufficiently reliable and subjective classical techniques of visual plant analysis and quantifying the disease severity based on scales with a numerical range. Semi-automatic digital techniques in the form of smartphone applications (Leaf Doctor) or softwares (ImageJ) are objective, simple, faster and more reliable techniques for assessing the disease severity. The smartphones application (Leaf Doctor) is a more reliable and accessible technique in contrast to the computer software (ImageJ), especially in field research, because it provides real-time results of assessing the disease severity. In addition to numerous advantages, there are disadvantages in the application of digital techniques due to the demanding criteria in achieving a high-quality image on a suitable background. Also, introduced digital techniques for quantifying symptoms based on photos are of great importance, especially in leaf diseases, and personal skill and expertise play a significant role in the performance of photo analysis. Despite the strict criteria for obtaining a high-quality image for analysis, digital techniques are a valuable tool in phytopathological studies that needs further refinement and training of users with the aim of increasing the possibility of daily use in phytopathology, as well as in integrated plant production.
