“…Research on microorganisms for plant disease control is becoming increasingly popular in the applied biology. Many species of bacteria and fungi have been comprehensively researched (Mrabet et al, 2013;Koch, Roberts, 2014;Sharma et al, 2015;Mirmajlessi et al, 2016;O'Callaghan, 2016). Evaluation of effect of bacterial product Cedomon on spring barley grain yield in Sweden showed that the mean increase of yield was 2-5% during research period 1991-1996 (Johnsson et al, 1998).…”

“…Cereals occupy about one third of the total organically cropped area in the EU and it ranges from 18% (the Netherlands) to 63% (Lithuania) (Eurostat, 2019). One of the main obstacles in organic farming is seed health of cereals (Clark, Cockerill, 2011;Koch, Roberts, 2014). Organic farmers are very unwilling to buy organic certified seeds due to their higher price compared to the conventional seeds.…”

“…Many simple and sophisticated seed treatment methods have been developed and tested under different coverage during the last several decades (Clark, Cockerill, 2014;Koch, Roberts, 2014;Sharma et al, 2015;Araujo et al, 2016). However, only a few methods are applied under industrial level for cereals due to high seed amounts needed (BioAgri, 2017; Evonta, 2019).…”

Low energy electrons (electron treatment), aerated steam (thermal treatment) and a bacterial product Cedomon containing Pseudomonas chlororaphis (bacterial treatment) were selected for the trial as the most popular seed treatment methods in Western and Northern Europe. This trial was aimed to evaluate the effect of treatments on seed sanitation, crop and disease development and yield parameters. Two spring barley (Hordeum vulgare L.) cultivars 'Luokė' and 'Alisa DS' were investigated during 2014-2015 under the conditions of Central Lithuania. Low energy electron treatment was found to exert a negative effect: the mean yield decrease was 20% compared to the control. The yield reduction resulted from the inefficient seed sanitation and reduced field emergence compared to the control. Thermal treatment increased the yield by an average of 35%, viz. in 2014 by 58% and in 2015 by 13%. The yield increase was influenced by very efficient seed sanitation in the first year but not in the second year. Bacterial treatment with Cedomon increased the yield by an average of 3%. This treatment improved neither seed health nor crop stand density in 'Luokė'; however, it had a positive effect on the seeds of 'Alisa DS' in both experimental years. Improved seed health increased grain yield in 'Alisa DS', while poor seed health decreased yield in 'Luokė'. None of the seed treatment methods tested showed consistent and unquestionable results. The yield increase depended mainly on the improved seed health, thus the main strategy to produce stable yield is seed health testing of the lots intended for use in organic agriculture.Please use the following format when citing the article: Liatukas Ž., Supronienė S., Ruzgas V., Leistrumaitė A. 2019.

“…In order to further reduce the risk from seed‐borne pathogens, it is recommended that stock seeds should undergo precautionary decontamination treatments. Chemical seed treatments have successfully been applied to vegetable seeds and are in commercial use for a wide range of crops against different seed‐borne pathogens (Munkvold, ; Koch & Roberts, ). Heat treatments with hot water, aerated steam or dry heat can be very effective, but they need to be optimized due to the differences in temperature and time required for different target pathogens and crops (Nega et al ., ; Koch & Roberts, ).…”

Emerging foliar and soil‐borne pathogens of leafy vegetable crops: a possible threat to Europe

Italy is one of the leading countries for the production and consumption of ready‐to‐eat salads. This has led to a steady increase in the area used over the last decade for the growth of leafy vegetables under intensive systems. The recent new diseases that affect lettuce, wild and cultivated rocket, lamb's lettuce, spinach and basil are reported here: Plectosphaerella cucumerina on wild rocket, endive and lamb's lettuce, Fusarium equiseti on wild and cultivated rocket and lettuce, Myrothecium verrucaria on spinach and wild rocket, Myrothecium roridum on lamb's lettuce, Allophoma tropica on lettuce and Alternaria sp. on basil and rocket are among the new foliar pathogens in Italy. Among the soil‐borne pathogens, Pythium aphanidermatum, Pythium irregulare and Pythium Cluster B2a have recently been isolated in Italy on spinach and Swiss chard, lamb's lettuce and lettuce, while Fusarium oxysporum f. sp. lactucae, which causes lettuce wilt, is gradually spreading to new countries. Some of the new pathogens have been found to be transmitted by seed and typical of tropical climate, and are thus favoured by the increases in temperature linked to climate change. The globalization of markets, climate change and intensive cultivation are among the factors responsible for the proliferation and spread of some of these new pathogens that are ‘alien’ to Italian production systems.

Design and effectiveness of pulsed electric fields towards seed disinfection

BACKGROUND Seeds harbor different microorganisms on their surfaces that degrade seed quality, thus causing an economic loss. Even though different approaches are available for the disinfection of seed surfaces, there is a need to develop environmentally friendly and sustainable technologies. A bench‐scale pulsed electric field (PEF) unit was designed to inactivate microflora of eight seeds after which the resultant vigor of the treated seeds was determined. RESULTS Significant reductions were obtained in endogenous natural and inoculated pathogenic (Alternaria brassica and Xanthomonas campestris pv. campestris, Drechslera graminea and Fusarium graminearum) microflora of seeds. The survival ratios of total aerobic mesophilic bacteria and of total mold and yeast decreased significantly for winter wheat and barley, parsley, onion, lettuce, tomato, and garden rocket with the PEF treatments of 240 and 960 J. A significant increase in germination ratio was observed for winter wheat and barley, lettuce, and tomato with 960 J. Germination energy increased for parsley with 240 J and for winter wheat and barley, lettuce, tomato, and garden rocket with 960 J. A better root development and seedling were found for winter barley. CONCLUSION PEFs are a viable option to both disinfect seed surfaces and improve seed vigor. © 2019 Society of Chemical Industry
