Opis:
Grain samples of two maize hybrids, medium early (ZP434) and late maturity (ZP704), collected during  harvest in 2008 were investigated for contamination by fungi. Grains were plated on agar media and grown  fungi were identified by morphological macroscopic and microscopic characteristics on potato-dextrose agar  (PDA) and synthetic nutrient agar (SNA). Species of the genus Fusarium were the most common in both hybrids, and their presence amounted to 33.89% (ZP434) and 42.00% (ZP704). Other fungi of genera, Acremonium, Alternaria, Aspergillus, Chaetomium, Cladosporium, Nigrospora, Penicillium, Rhizopus and Trichotecium, were isolated from 0 to 41.00%. Four species belonging to the genus Fusarium were identified, of which the species F. verticillioides was the most common with 28.63% in ZP434 and 30.50% in ZP704 hybrids. The presence of F. graminearum, F. proliferatum and F. subglutinans ranged from 3.00% (ZP704) to  .00% (ZP434), 0.13% (ZP434) to 7.00% (ZP704) and 0.13% (ZP434) to 7.00% (ZP704), respectively. Generally, the incidence of every particular fungus was higher in the late maize hybrid with a higher moisture  content than in the medium-early hybrid with a lower moisture content.

Opis:
The aim of the study was to assess the fungistatic activity of supernatants obtained from 4, 6, 8, 10 and 24-hour culture of Bacillus KF2 and Bacillus BK2 against Fusarium spp. The antagonistic activity was evaluated on the basis the rate index of fungal growth on Czapek-Dox and PDA media. The rate index of Fusarium spp. growth on PDA medium was 5-fold and 3.5-fold slower than in the control, after application of supernatants obtained from the 24-hour culture (respectively for Bacillus KF2 and Bacillus BK2). Similarly, a high antifungal activity of the tested strains was observed on Czapek-Dox medium. The growth of Fusarium spp. was 6-fold and 3.5-fold slower after application of supernatants obtained from 6-hour culture, respectively, for Bacillus KF2 and Bacillus BK2. Supernatants obtained from the culture of both strains showed fungistatic activity against Fusarium spp., although the Bacillus KF2 strain showed a stronger impact than Bacillus BK2 strain. The inhibitory properties of Bacillus species was depended on the age of the bacterial culture and/or strains of Bacillus, and the composition of the medium. The experimental results exhibit the fungistatic activity of Bacillus strains and indicate the possibility of use their as antifungal agents against Fusarium spp.
Celem podjętych badań była ocena aktywności fungistatycznej supernatantów otrzymanych z 4-, 6-, 8-, 10- i 24-godzinnych hodowli Bacillus KF2 i Bacillus BK2 wobec Fusarium spp. Ocenę właściwości antagonistycznych metabolitów bakteryjnych przeprowadzono metodą hodowlano-płytkową z zastosowaniem podłoży Czapka i PDA. Tempo wzrostu Fusarium spp. na podłożu PDA było 5-krotnie oraz 3,5-krotnie wolniejsze niż w próbce kontrolnej, po zastosowaniu supernatantów uzyskanych z 24-godzinnej hodowli, odpowiednio dla Bacillus KF2 i Bacillus BK2. Podobnie dużą aktywność przeciwgrzybową badanych szczepów stwierdzono na podłożu Czapka. Indeks tempa wzrostu Fusarium spp. był 6-krotnie oraz 3,5-krotnie wolniejszy po zastosowaniu supernatantów z 6-godzinnej hodowli, odpowiednio dla Bacillus KF2 i Bacillus BK2. Supernatanty otrzymane z hodowli obu szczepów wykazały działanie fungistatyczne wobec Fusarium spp. przy czym silniejszy wpływ wykazał Bacillus KF2. Stopień zahamowania wzrostu Fusarium spp. zależał od gatunku bakterii, wieku jej hodowli, rodzaju podłoża i czasu trwania hodowli. Uzyskane wyniki badań wykazały aktywność fungistatyczną szczepów Bacillus spp. i wskazują na możliwość wykorzystania ich jako środków przeciwgrzybiczych wobec Fusarium spp.

Opis:
The fusarium dry rot is one of the most important diseases of potato tubers causing considerable damages during the storage. Resistance sources are one of the fundamental methods in prevention and disease control. This study details the pathogenesity and assessment of susceptibility of commercially acceptable potato Cultivars to dry rot causing by Fusarium sulphureum , F. solani and F. oxysporum under similar conditions includings . inoculum , mehtod of inoculation, temperature , relative humidity and light. The results indicated that though the similar conditions were applied, the tubers of varieties reacted with differing levels of resistance to the species causing the disease. It was found that F. sulphureum was the most aggressive one, then fallowed by F. solani as far as the disease development is concerned and were independent. F. oxysporum did not cause considerable damages. In these expriments the commerical potato varieties were Seuminar, Rustica, clivastave, Dital, Escort, Monalisa, Marfona, Mondial, Aniona, Deraga, Asta, Hidram, Melisa, Moren, Mariyana, Pashandi, Frasco, Alva, Ceaser, Asva, Aula, Sandara , Marijke, Folva, Tiva, Fregate, Baraka, Aida, Diamant, Arnica, Panda, Atlas, Erigo, Volkano, Famosa, Carlita, Korrigan, Casmos, Assour, Cosima, Ariane, Desiree and saturna, in which started with most susceptible ones fallowed to resistance ones at end to F.sulphureum. The variety saturna were the most resistant one to the all tested species in these expriments.

Opis:
Field trials conducted at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and For- estry (central part of Lithuania) in 2009 were aimed to evaluate the effect of fungicides on Fusarium Head Blight (FHB) in a naturally infected field. A single application of dimoxystrobin + epoxiconazole (Swing Gold), prothioconazole (Proline), metconazole (Juventus), tebuconazole (Folicur), prothioconazole + tebu- conazole (Prosaro) was applied to winter wheat cv. ‘Zentos’ at the manufacturer’s recommended doses at anthesis (BBCH 65). The FHB incidence and severity were assessed at milk and hard maturity stages. The percentage of Fusarium infected grain and deoxynivalenol (DON), zearalenone (ZEN) and T-2 toxin (T-2) concentrations in harvested grain were determined. In all fungicide treated plots a significant reduction of FHB incidence and severity was determined; however the fungicides did not exert any effect on the amount of Fusarium–infected grain as compared with the untreated control. A reduction of  DON, ZEN and T-2 contents in grain was determined in tebuconazole treatments. Fusarium avenaceum (Fr.) Sacc, F. culmorum (W. G. Sm.) Sacc., F. poae (Peck) Wollenw, F. sporotrichioides Sherb. and F. tricinctum (Corda) Sacc were identi- fied in wheat grain, F. poae was prevalent.

Opis:
Ears of winter wheat cultivars (Bogatka and Legenda) grown under conventional and ecological (organic) farming systems, were sampled at different developmental stages and examined for their colonization by filamentous fungi, including Fusarium spp. Ears samples were shaken in sterile water containing 0.01% of Tween 80 and appropriate 10-fold dilutions of the initial suspension were inoculated onto agar medium containing antibiotics to inhibit bacterial contaminants. After 6-7 days of incubation at 28o C fungal colonies were counted and after further 4 days fragments of colonies were transferred onto other media for identification. On ears at flowering no Fusarium species were found in 2008 with dry and hot July, but in 2009 with more frequent rainfalls in July Fusarium poae, F. tricinctum and F. avenaceum were detected on winter wheat ears at the flowering stage. At the hard kernel stage the following species were isolated from winter wheat ears: F. poae and F. sporotrichioides in 2008 (17 and 18 isolates respectively) and F. avenacum, F. crookwellense, F. poae, F. sporotrichioides and F. tricinctum in 2009 (2, 18, 39, 2 and 17 isolates respectively, and 9 unidentified Fusarium). In 2008 more Fusarium spp. were found on winter wheat ears grown under the conventional system than under the ecological (organic) system. In the ecological system wheat stands are thinner but taller (due to the lack of any mineral fertilizers and plant growth regulators) and in consequence winter wheat ears in this system may keep moisture shorter than those in the conventional system. It seems that this difference may be the most important factor influencing colonization of winter wheat ears by Fusarium spp. and other fungi under the compared farming systems.

Opis:
The aim of the research was the laboratory evaluation of the fungistatic effect of the Zielony Busz (ZB) organic-mineral fertiliser on the linear growth of polyphagic phytopathogenic fungi Alternaria alternata, Colletotrichum coccodes, Fusarium avenaceum, Fusarium equiseti and Fusarium oxysporum. The preparation was applied to the medium (PDA potato-glucose agar) in concentrations of 2% and 5%, compared to 0.05% azox- ystrobin (relative control) and pure PDA medium (absolute con- trol). The strongest antifungal effect of the Zielony Busz fertilizer was found at the 5% concentration in reference to A. alternata (inhibition of colony growth at the level of 50–52% compared to the absolute control; 20–41.7% compared to azoxystrobin) and C. coccodes (18.2–53.3% growth inhibition compared to abso- lute control). Weaker inhibitory effect of 5% concentration of the fertilizer was noted against F. avenaceum (10.5% inhibition of colony growth compared to absolute control) and F. oxysporum (20% inhibition compared to absolute control), but only at the beginning of the experiment. The Zielony Busz fertilizer at a con- centration of 2% caused the surface growth of all tested fungi, especially F. equiseti. The best effects of the fungistatic effect of the fertilizer were obtained in the first days of the experiment (4th day) with a 5% concentration of the product in the substrate. With time, the antifungal activity of fertilizer decreased significantly

Opis:
Oilseeds are a perfect medium for microfungi spread and mycotoxin production. With increasing demand for oil crop produce such research has gained a special relevance since research evidence on this issue is scarce. During 2007-2009, prevalent fungi genera, including Fusarium genus, potential producer of deoxynivalenol (DON), zearalenone (ZEA), T-2 toxin (T-2) etc. were determined in our tests. The ELISA immunoenzymatic method and Veratox Fast kits were used to identify and quantify mycotoxins, while Fusarium fungi species were identified using conventional fungi determination techniques. Higher Fusarium fungi contamination level was found on linseed compared with that on spring or winter rapeseed. The difference was even more obvious in different experimental years, however, having identified Fusarium species, F. avenaceum and F. oxysporum were found to be prevalent in the seed of all crop species tested. In 2009, spring rape samples were found to contain F. dimerum which is a significant human pathogen.The presence of DON was identified in 18.2-100%, ZEA in 40 -100%, and T-2 toxin in 100% of seed samples of all oil crop species tested. From the food safety viewpoint, the concentrations determined did not exceed the levels hazardous for health, laid out in the EU regulations, however, the effect of low toxin concentrations is slow and the negative consequences manifest themselves only after some time and in various forms, which poses a serious health risk for humans and animals.
