Epidemics of early blight caused by Alternaria spp. can cause significant economic damage to potato production if not adequately controlled. In order improve control in potato, studies were conducted identify the optimal fungicide strategy and, possible, reduce number applications per growing season. Therefore, a disease-threshold-based framework was tested define timing application. The initiation and subsequent fungicides based on increases disease incidence or severity. Adequate achieved...
Early blight caused by A lternaria solani is a highly destructive disease of potatoes. Control early mainly relies on the use preventive fungicide treatments. Because their high efficacy, azoxystrobin and other quinone outside inhibitors ( Q o I s) are commonly used to manage blight. However, loss sensitivity s has previously been reported for . in U nited S tates. Two hundred three field isolates collected from 81 locations G ermany between 2005 2011 were screened presence F 129 L mutation...
<title>Abstract</title> Late blight (<italic>Phytophthora infestans</italic>) is a major disease in potato cultivation, managed primarily with synthetic fungicides. This reliance makes potatoes one of the crops highest fungicide load. To reduce chemical dependence and promote Integrated Pest Management (IPM), alternative solutions are needed. study explores biological control agents (BCAs) plant resistance inducers (PRIs) as sustainable alternatives. We screened 17 BCAs 3 PRIs detached leaf...
The Global Plant Health Assessment (GPHA) is a collective, volunteer-based effort to assemble expert opinions on plant health and disease impacts ecosystem services based published scientific evidence. GPHA considers range of forest, agricultural, urban systems worldwide. These are referred as (Ecoregion × System), i.e., selected case examples involving keystone plants in given parts the world. focuses infectious diseases pathogens, but encompasses abiotic (e.g., temperature, drought,...
α-Solanine and α-chaconine are the major glycoalkaloids (SGAs) in potatoes, but up to now biosynthesis of these saponins is not fully understood. In planta 13CO2 labeling experiments monitored by nuclear magnetic resonance spectroscopy (NMR) high-resolution mass spectrometry (HRMS) unraveled SGA biosynthetic pathways from CO2 photosynthates via early precursors SGAs. After a pulse ~ 700 ppm for four hours, followed chase period seven days, specific 13C-distributions were detected SGAs leaves...
Plant pathogens such as Phytophthora infestans that caused the Irish Potato Famine continue to threaten local and global food security. Genetic chemical plant protection measures are often overcome by adaptation of pathogen population structures. Therefore, there is a constant demand for new, consumer- environment-friendly strategies. Metabolic alterations induced P. in foliage tubers six different potato cultivars were investigated. Using combination untargeted metabolomics, isolation...
Early blight of potato is caused by the fungal pathogen Alternaria solani and an increasing problem worldwide. The primary strategy to control disease applying fungicides such as succinate dehydrogenase inhibitors (SDHI). SDHI-resistant strains, showing reduced sensitivity treatments, appeared in Germany 2013, shortly after introduction SDHIs. Two mutations SDH complex (SdhB-H278Y SdhC-H134R) have been frequently found throughout Europe. How these resistances arose spread, whether they are...
Breeding for resistance is a key task to control Fusarium head blight (FHB), devastating disease of small cereals leading economic losses and grain contamination with mycotoxins harmful humans animals. In the present work, FHB six-rowed spring barley 'Chevron' in Germany was compared those adapted German cultivars. Both under natural infection conditions after spray inoculation conidia culmorum, F. sporotrichioides, avenaceum field conditions, Chevron showed high level quantitative diverse...
Fusarium head blight (FHB) of small cereals is a disease global importance with regard to economic losses and mycotoxin contamination harmful human animal health. In Germany, FHB predominantly associated wheat F. graminearum recognised as the major causal agent disease, but little known about barley. Monitoring natural occurrence on Bavarian barley revealed differences for individual spp. in incidence severity grain infection between years spring winter Parallel measurement fungal DNA...
The fungus Alternaria solani is the main pathogen causing early blight on potatoes (Solanum tuberosum L.). An increase in development of resistance to succinate dehydrogenase inhibitor (SDHI) boscalid, one active ingredients for control blight, has been reported. For this study, monitoring data from Germany were collected between 2013 and 2016 an occurrence A. (SDH) mutant isolates was observed. In addition known point mutations sdh complex II, a new mutation subunit C found German...
Although domesticated potatoes contain a large variety of steroidal glycoalkaloids (SGAs) and saponins, in the past, many research projects mainly focused on two major SGAs, α-solanine α-chaconine. This study investigates quantitative changes, induced by post-harvest LED light exposure, six SGAs four saponins 12 potato cultivars at three different time points (1, 7, 16 days), using ultra-performance liquid chromatography tandem mass spectrometry. Altogether, SGA contents 3.0-17.1 mg/100 g...
