20.500.12556/DiRROS-27865 Climate change impacts on plant diseases and crop protection Vpliv podnebnih sprememb na rastlinske bolezni in varstvo rastlin Climate change is considered one of the greatest threats to agriculture, resulting in significant yield losses and the loss of arable land due to various factors, ranging from unfavorable climate conditions to soil fertility issues. One significant aspect of climate change affecting crops is the development of diseases. The main factors of climate change affecting agriculture are the increase in temperature and CO2 levels, as well as the alteration of precipitation regimes, which can lead to extreme weather events such as droughts and floods. These factors considerably affect pathogens' expression of disease in hosts, as well as their spatial and temporal distribution and life cycle limiting factors, which are now changing. Early studies show an increase in the severity and occurrence of diseases caused by pathogens in crops, a reduction in plant defense mechanisms, the emergence of new, adapted, and more aggressive pathogen strains, and a wider and faster expansion of pathogens. However, the efficacy of plant protection products is also reduced. However, each pathosystem is affected differently by climate change, and mitigating effects must be studied independently. Podnebne spremembe veljajo za eno največjih groženj kmetijstvu, saj povzročajo znatne izgube pridelka in izgubo obdelovalnih zemljišč zaradi različnih dejavnikov, od neugodnih podnebnih razmer do vpliva na zmanjšanje rodovitnosti tal. Eden od pomembnih vidikov podnebnih sprememb, ki vplivajo na kmetijske rastline, je razvoj bolezni. Glavni dejavniki podnebnih sprememb, ki vplivajo na kmetijstvo, so povišanje temperature in ravni CO2 ter sprememba režimov padavin, kar lahko privede do ekstremnih vremenskih pojavov, kot so suše in poplave. Ti dejavniki znatno vplivajo na izražanje bolezni patogenov pri gostiteljih, pa tudi na njihovo prostorsko in časovno porazdelitev ter dejavnike, ki omejujejo življenjski krog, ki se zdaj spreminjajo. Zgodnje študije kažejo povečanje resnosti in pojava bolezni, ki jih povzročajo rastlinski patogeni, zmanjšanje obrambnih mehanizmov rastlin, pojav novih, prilagojenih in agresivnejših sevov patogenov ter širše in hitrejše širjenje patogenov. Vendar pa se zaradi podnebnih sprememb zmanjša tudi učinkovitost fitofarmacevtskih sredstev. Podnebne spremembe različno vplivajo na patosisteme, blažilne učinke pa je treba preučiti neodvisno. global warming food security plant pathogens plant pathology globalno segrevanje prehranska varnost rastlinski patogeni fitopatologija true false true Angleški jezik Slovenski jezik Inštitut za hmeljarstvo in pivovarstvo Slovenije Neznano 2026-02-26 12:03:28 2026-02-26 12:03:28 2026-03-07 03:51:39 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 19. 12. 2025; str. 101-110 Št 32 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2025-12-19 632.38 2536-1988 262361091 https://www.dlib.si/details/URN:NBN:SI:spr-OS4I5CDJ 1 c822a1e6-1302-11f1-9cb0-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=41000 CLIMATE_CHANGE_IMPACTS_ON_PLANT_DISEASES_AND_CROP_PROTECTION.pdf CLIMATE_CHANGE_IMPACTS_ON_PLANT_DISEASES_AND_CROP_PROTECTION.pdf 1 F99DE2AF8CEF88ABA91055150D441E68 3588c1dcbd42af2c5017faba0dedd96f9484d422f887a50d40ba3da343c23f9c 0b9d1e0f-1947-11f1-81cd-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=41356 Inštitut za hmeljarstvo in pivovarstvo Slovenije Hmeljarski bilten 0 0 0
