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:: Durum wheat production in Italy is economically of great importance. Fusarium graminearum is the main fusarium head blight (FHB) causal agent in wheat, reducing both yield and grain quality. F. graminearum produces several mycotoxins and, among trichothecenes, deoxynivalenol (DON) and nivalenol (NIV) are the most studied for their toxicity towards humans and animals. DON-producing isolates can be further distin- guished on the basis of the predominant acetyl-DON derivative in 3-acetyldeoxynivalenol (3-ADON) or 15- acetyldeoxynivalenol (15-ADON). In order to evaluate possible mycotoxin contamination risks in food, it is very important to know which chemotype is the prevalent in a F. graminearum population. F. graminearum sensu stricto strains were collected from symptomatic durum wheat heads and grains of several naturally infected fields located mostly in Emilia – Romagna, The Marche, Lazio, Tuscany and Umbria. A multiplex PCR in the region of genes Tri12, located in the terminal gene cluster of trichothecenes, was used to characterize 187 single-spore isolates of F. graminearum as NIV, 3-ADON and 15-ADON chemotypes. All the three chemotypes were present in the F. graminearum population studied. The most frequent chemotype was 15-ADON (83.4%), followed by 3-ADON (10.7%) and NIV (5.9%). NIV-producing isolates were found only in Emilia-Romagna (3.5%), Umbria (33.3%) and The Marche (5.7%).

Opis:: Eighteen spring wheat cultivars, recommended for commercial production in northern Poland, were assessed for Fusarium head blight (FHB) in natural non-epidemic conditions, from 2011 to 2013. Assessment was based on FHB incidence (proportion of heads with symptoms), disease severity (DS; proportion of bleached spikelets per head), proportion of Fusarium damaged kernels (FDK), and spectrum of Fusarium spp. colonising the kernels. Fusarium head blight incidence and DS often differed significantly among cultivars and years. There was a strong positive correlation between FHB incidence and DS. Fusarium head blight incidence and DS were not correlated with the June–July temperatures, and were only occasionally correlated with the total June–July rainfall. There was a weak positive correlation between FHB incidence and proportion of FDK. There was a strong positive correlation between DS and proportion of FDK. The cultivar affected colonisation of kernels by Fusarium spp. Fusarium poae was the FHB pathogen isolated most often. Fusarium poae colonised 6.0% of the kernels, on average, but up to 12.0% on individual cultivars. Other Fusarium species were less frequent: F. avenaceum in 5.6% of kernels, F. culmorum in 5.3%, F. tricinctum in 2.8%, F. graminearum in 1.5%, and F. sporotrichioides in 1.2%. Fusarium equiseti occurred sporadically. The importance of F. poae in the FHB complex is emphasised. All cultivars expressed ‘moderate FHB resistance’ if evaluated according to FHB incidence. Cultivars Arabella, Izera, Kandela, Monsun, Ostka Smolicka, and Struna expressed ‘moderate susceptibility’, and Bombona, Hewilla, Katoda, KWS Torridon, Łagwa, Nawra, Parabola, Radocha, SMH 87, Trappe, Tybalt, and Waluta expressed ‘susceptibility’ if evaluated by the proportion of FDK. Cultivars differed within the ‘moderately resistant’, ‘moderately susceptible’, and ‘susceptible’ categories. Cultivars Arabella, Izera, Kandela, Monsun, Ostka Smolicka, and Struna were the most promising and their resistance traits may be useful in FHB management.

Opis:: Although Syrian high-yielding wheat cultivars grown under Mediterranean conditions include acceptable levels of resistance to biotic constraints, little is known about their susceptibility to Fusarium head blight (FHB), a harmful disease of wheat cultivation worldwide. The capacity of 16 fungal isolates of four FHB species to confer the disease on spikes and spikelets of six widely grown old and modern Syrian durum and bread wheat cultivars with known in vitro quantitative resistance to FHB was evaluated. Quantitative traits were visually assessed using spray and point inoculations for determining disease development rates, disease incidence (DI) and disease severity (DS) under controlled conditions. Differences in pathogenicity and susceptibility among wheat cultivars were observed, emphasizing the need for breeders to include aggressive isolates or a mixture of isolates representative of the FHB diversity in their screenings for selection of disease resistant cultivars. Bread wheat cultivars showed lower levels of spike and spikelet damage than durum cultivars regardless of the date of cultivar release. Overall, the six wheat cultivars expressed acceptable resistance levels to initial fungal infection and fungal spread. Quantitative traits showed significant correlation with previous standardized area under disease progress curve (AUDPCstandard) data generated in vitro. Thus, the predictive ability of AUDPCstandard appears to be crucial in assessing pathogenicity and resistance in adult wheat plants under controlled conditions. While in the Mediterranean countries the risk of disease is progressively increasing, the preliminary data in this report adds to our knowledge about four FHB species pathogenicity on a Syrian scale, where the environment is quite similar to some Mediterranean wheat growing areas, and show that Syrian cultivars could be new resistant donors with favorable agronomical characteristics in FHB-wheat breeding programs.

Opis:: Fusarium graminearum and F. culmorum are the causal agents of Fusarium head blight (FHB) in cereal crops worldwide. Application of resistant cultivars is the most effective and economic method for management of FHB and reducing mycotoxin production in wheat. Understanding the physiological and biochemical mechanisms involved in basal resistance of wheat to FHB disease is limited. In this research, after screening resistance levels of eighteen wheat cultivars planted in Iran, Gaskozhen and Falat were identified as partially resistant and susceptible wheat cultivars against Fusarium spp., respectively. Also, we investigated the role of hydroxyl radical (OH−), nitric oxide (NO), callose deposition, lipid peroxidation and protein content in basal resistance of wheat to the hemi-biotrophic and necrotrophic Fusarium species causing FHB. Nitric oxide as a signaling molecule may be involved in physiological and defensive processes in plants. Our results showed that NO generation increased in seedlings and spikes of wheat cultivars after inoculation with Fusarium species. We observed earlier and stronger callose deposition at early time points after infection by Fusarium spp. isolates than in non-infected plants, which was positively related to the resistance levels in wheat cultivars. Higher levels of OH− and malondialdehyde (MDA) accumulation (as a marker of lipid peroxidation) were observed in the Falat than in the Gaskozhen cultivar, under non-infected and infected conditions. So, estimation of lipid peroxidation could be useful to evaluate cultivars’ susceptibility. These findings can provide novel insights for better recognition of physiological and biochemical markers of FHB resistance, which could be used for rapid screening of resistance levels in wheat cultivars against this destructive fungal disease.

Opis:: The aim of the study was to determine the presence of Fusarium species and mycotoxins in wheat grain from harvest in 2009 and 2010 in Poland. Samples from different locations were analyzed for the content of DNA of Fusarium species and mycotoxins. In 2009, DNA of F. graminearum and F. poae was present in all samples, F. culmorum in 82% of samples, and F. avenaceum in 55% of samples. In 2010, the highest content of DNA was found for F. graminearum followed by F. avenaceum, F. poae and F. langsethiae. The amount of F. culmorum DNA was very low. The most frequently occurring species were F. poae and F. graminearum, however, the amount of F. poae DNA was lower. In 2009, deoxynivalenol was detected in all samples. In 2010, the average content of deoxynivalenol was lower than in 2009. Nivalenol was detected at very low concentration in both years. Significant correlations between content of F. graminearum DNA and deoxynivalenol concentration in the grain and between content of F. poae DNA and nivalenol concentration in the grain in 2009 were found.
Celem badania było określenie obecności gatunków Fusarium i mykotoksyn występujących w ziarnie pszenicy w Polsce w latach 2009 i 2010. Próby ziarna pochodzące z różnych regionów Polski zostały przeanalizowane pod kątem zawartości DNA grzybów z rodzaju Fusarium oraz mykotoksyn. W 2009 roku DNA F. graminearum i F. poae było obecne we wszystkich próbach, F. culmorum w 82% prób, F. avenaceum w 55% próbek. W 2010 r. najwyższą zawartość DNA stwierdzono dla F. graminearum, a następnie F. avenaceum, F. poae i F. langsethiae. Ilość DNA F. culmorum była bardzo niska. Najczęściej występującymi gatunkami były F. poae i F. graminearum. Jednakże ilość DNA F. poae była niższa. W 2009 r. we wszystkich próbach wykryto deoksyniwalenol. W 2010 r. średnia zawartość deoksyniwalenolu była niższa niż w 2009 r. Niwalenol wykryto w bardzo niskim stężeniu w obu latach. Stwierdzono istotność korelacji między zawartością DNA F. graminearum a stężeniem deoksyniwalenolu w ziarnie oraz między zawartością DNA F. poae a stężeniem niwalenolu w ziarnie w 2009 r.

Opis:: Investigations on Fusarium head blight of rye were carried out in the years 2005-2007 on 10 production fields in the Lublin region. The percentage of heads showing the fusariosis symptoms in the years 2005-2007 ranged from 0 to 7%. Mycological analysis of kernels and chaff obtained from heads with Fusarium blight (scab) symptoms showed that Fusarium avenaceum, Fusarium culmorum and Fusarium sporotrichioides were the largest threat to heads of this cereal. The species of Fusarium poae and Fusarium crookwellense were also isolated from infected rye heads. The dominance of particular species in infecting rye heads was determined by weather conditions.

Opis:: Quantitative resistance in barley to four Fusarium head blight (FHB) species was investigated in vitro. Nine components involved in three assays (detached leaf, modified Petridish and seedling tests) were compared on two widely grown Syrian barley cultivars: Arabi Aswad (AS) and Arabi Abiad (AB). On AB, inoculation with FHB species resulted in a significantly shorter latent period and larger lesion length of detached leaf inoculation, more standardized area under disease progress curve (AUDPCstandard) of modified Petridish inoculation and a higher percentage of infected seedlings of pin-point inoculation than on AS. The latent period of AB was 14.89% less than AS, lesion length of AS was 6.01% less than AB, AUDPCstandard of AS was 17.07% less than AB and the percentage of infected seedlings of AS was 4.87% less than AB. Inoculation with FHB species resulted in no significant differences in the other five components measured: incubation period of detached leaf inoculation, germination rate reduction and coleoptile length reduction of modified Petridish inoculation, percentage of infected seedlings of foliar-spraying inoculation and lesion length of clip-dipping inoculation. AS was more resistant to in vitro FHB infection than AB. The latent period and AUDPCstandard recorded the highest values compared with the lowest values for lesion length and percentage of infected seedlings. It seems that measurement of the latent period and AUDPCstandard may be useful in identifying barley cultivars which are highly susceptible or resistant to FHB at early stages.

Opis:: In Latvia, climatic factors are influential in spreading of Fusarium head blight of cereals caused by Fusarium species. The most significant factor affecting the incidence of the disease in winter wheat is hightened temperature at the time of wheat anthesis. Field trials for the control of the disease in winter wheat were done in 2003-2004 using new fungicides applied at various rates by natural infection and artificial inoculation. Three species of causative agents: Fusarium avenaceum var. herbarum, F. gibbosum, F. culmorum were collected from infected seeds of wheat and used for inoculation of experimental plots at the concentration 106 conidia ml-1 (1:1:1) at the stage of full anthesis. Effective control of the disease was obtained through application of new fungicides with different active ingredient: Prosaro 250 EC (tebuconazole 125 G, prothioconazole 125 G L-1), Input 460 EC (spiroxamine 300 G, prothioconazole 160 G L-1). In conditions of artificial infection by severe attack of Fusarium spp. the application of fungicides containing tebuconazole at T3 gave significant influence on yield of winter wheat through plumpness of grains increase. High efficacy of fungicides against leaf infection with Erysiphe graminis and Drechslera tritici-repentis was also in the trial achieved. Application of fungicide containing cyproconazole and trifloxystrobin at T1 in the trial 2004 gave good control of Septoria tritici, E. graminis and D. triticirepentis.
Na Łotwie czynniki klimatyczne mają wpływ na szerzenie się fuzariozy zbóż wywołanej gatunkami Fusarium. Najważniejszym czynnikiem wpływającym na występowanie choroby w pszenicy ozimej jest podwyższona temperatura w czasie kwitnienia pszenicy. W latach 2003-2004 przeprowadzono badania polowe zwalczania choroby w pszenicy ozimej za pomocą nowych fungicydów stosowanych w różnej ilooeci poprzez naturalne zakażenie i sztuczną inokulację. Trzy gatunki czynników sprawczych: Fusarium avenaceum var. herbarum, F. gibbosum, F. culmorum, zebrano z zakażonych ziaren pszenicy i użyto do inokulacji poletek doświadczalnych przy stężeniu 106 konidiów na ml-1 (1:1:1) w fazie pełnego kwitnienia. Uzyskano skuteczne zwalczanie choroby poprzez zastosowanie nowych fungicydów z różnymi aktywnym składnikami: Prosaro 250 EC (tebukonazol 125 G, propikonazol 125 G L-1), Input 460 EC (spiroksamina 300 G, propikonazol 160 G L-1). W warunkach sztucznego zakażenia poprzez ostry atak Fusarium spp., zastosowanie fungicydów zawierają- cych tebukonazol w okresie czasu T3 dało znaczny wpływ na plon pszenicy ozimej poprzez zwiększenie pulchności ziaren. W badaniu uzyskano również wysoką skuteczność fungicydów w zwalczaniu zakażenia liści wywołanym przez Erysiphe graminis i Drechslera tritici-repentis. Zastosowanie fungicydów zawierających cyprokronazol i trifloksystrobinę w okresie czasu T1 w badaniu w 2004 roku dało dobre zwalczanie Septoria tritici, E. graminis i D. tritici-repentis.
