“…This bacterium has strong ability to colonize spermosphere but poor ability to colonize coleoptile or rhizosphere. The consistent long term results prove that this bacterium is active in soil on grain but does not provide sufficient effect later (Hökeberg et al, 1997;Johnsson et al, 1998;BioAgri, 2019). (2017).…”

“…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). The further investigations during 1997-2003 showed that the mean increase of grain yield was 3-5% (BioAgri, 2019).…”

“…Their efficiency is highly variable and depends on the site, year, plant species and seed-borne pathogens. Using bacterial products, the yield increases in the majority of cases (Johnsson et al, 1998;BioAgri, 2017). Other methods belong to the group of physical treatment.…”

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.

“…Besides its biocontrol effect on V. dahliae in eggplant and potato, the bacterial BCA P. alvei K-165 reduced root discoloration and hypocotyl lesions caused by the black root rot fungus Thielaviopsis basicola on cotton seedlings (Tjamos et al, 2004; Schoina et al, 2011). Pseudomonas chlororaphis MA 342, which suppressed V. longisporum in oilseed rape, furthermore controls a wide range of cereal seed-borne diseases and is the active organism in the registered products Cedomon® and Cerall® (Johnsson et al, 1998; Abuamsha et al, 2011). …”

Desirable Traits of a Good Biocontrol Agent against Verticillium Wilt

et al. 2017

The soil-borne fungus Verticillium causes serious vascular disease in a wide variety of annual crops and woody perennials. Verticillium wilt is notoriously difficult to control by conventional methods, so there is great potential for biocontrol to manage this disease. In this study we aimed to review the research about Verticillium biocontrol to get a better understanding of characteristics that are desirable in a biocontrol agent (BCA) against Verticillium wilt. We only considered studies in which the BCAs were tested on plants. Most biocontrol studies were focused on plants of the Solanaceae, Malvaceae, and Brassicaceae and within these families eggplant, cotton, and oilseed rape were the most studied crops. The list of bacterial BCAs with potential against Verticillium was dominated by endophytic Bacillus and Pseudomonas isolates, while non-pathogenic xylem-colonizing Verticillium and Fusarium isolates topped the fungal list. Predominant modes of action involved in biocontrol were inhibition of primary inoculum germination, plant growth promotion, competition and induced resistance. Many BCAs showed in vitro antibiosis and mycoparasitism but these traits were not correlated with activity in vivo and there is no evidence that they play a role in planta. Good BCAs were obtained from soils suppressive to Verticillium wilt, disease suppressive composts, and healthy plants in infested fields. Desirable characteristics in a BCA against Verticillium are the ability to (1) affect the survival or germination of microsclerotia, (2) colonize the xylem and/or cortex and compete with the pathogen for nutrients and/or space, (3) induce resistance responses in the plant and/or (4) promote plant growth. Potential BCAs should be screened in conditions that resemble the field situation to increase the chance of successful use in practice. Furthermore, issues such as large scale production, formulation, preservation conditions, shelf life, and application methods should be considered early in the process of selecting BCAs against Verticillium.

“…Bacillus is also identified as potential bio-control agent used as alternatives to pesticide since they achieve disease suppression without negative effects on user, consumer or the environment [6]. Plant associated bacilli are recognized either as saprophytes, or as biological control agents.…”

Bacillus sp is one of the biocontrol agents are extensively used in management of fungal diseases of crop plants, exhibiting mycoparasitism against a wide range of plant pathogens. In the present investigation Efficacy of Bacillus subtilis was tested against Pythium aphanidermatum under glass house and field conditions. With regard to the germination and seedling growth parameters, the treatment T2 (liquid formulation of Bacillus subtilis @10 ml/L) recorded the highest germination percentage (92.59%), shoot length (59.3 cm), root length (24.3 cm), vigor index (7740.52) and yield (22.67 mt/ha). This was followed by the treatments T3, T1 and T4 in the decreasing order of merit. In the biometric observations also, 10 ml/L and 20 ml/L concentration of liquid formulation of Bacillus subtilis recorded statistically significant results. Observations on total protein content in brinjal plants treated with different concentrations of Bacillus subtilis revealed that treatment T2 was found best in both field and glass house conditions yielded highest protein as 0.44mg/ml and 0.30mg/ml respectively. The least values of germination, growth parameters, protein content and yield were observed in untreated control.
