“…These findings agree with those obtained by Cendoya et al [48] who recorded the maximum growth rate of the fumonisin-producer fungus F. proliferatum on irradiated wheat grains at 25 • C, while the best temperature for fumonisin production was at 15-25 • C. These results indicate the critical effect of temperature on the growth rate and mycotoxin production of F. proliferatum. In a recent study, it was found that the maximum germination rate of B. sorokiniana was obtained at 30 • C, while the minimum was observed at 10 • C, showing the vital influence of relatively high temperature on their sporulation [49]. These findings agree with those obtained in the present study.…”

Surveillance investigations for pathogenic and toxigenic fungi are important to refine our understanding of their epidemiology and help in predicting their outbreaks. During 2019, 198 samples of wheat grains were collected from 25 wheat-growing governorates in Egypt to detect and identify seed-borne mycoflora in vitro. Forty-four fungal species belonging to 20 genera were identified. Molecular data for these fungi were analyzed to construct a phylogenetic tree. Occurrence and biodiversity indicators were calculated. Two prevalent pathogens (average incidence > 40%) were Alternaria alternata and Cladosporium spp. Ustilago tritici was present in only seven of the 25 governorates, and less abundant than Tilletia tritici, the causal agent of stinking smut. Sinai governorate recorded the greatest species diversity, while the greatest species richness was in Qena and Sohag governorates. Canonical correspondence analysis of data for 20 fungal genera with temperature, relative humidity, precipitation, wind speed or solar radiation revealed that relative humidity was the most influential weather variable. It showed that occurrence and distribution of the 20 genera corresponded well with three out of four Egyptian climatic regions: Mediterranean, semi-arid, and arid. Knowing pathogen occurrence and distribution in Egypt is the first step to developing future disease management strategies to limit yield losses and improve food security. Despite this study being conducted on the wheat-growing areas in Egypt, our findings are useful for other wheat-growing countries that share the same climatic conditions. The correlation between a given fungus and the climatic variables can be useful in other ecosystems.

“…Para ambos, melhor crescimento foi verificado no regime de 12 h de luz, corroborando com Channakeshava e Pankaja (2018), que relataram uma maior capacidade de crescimento micelial de B. oryzae quando submetido a exposição alternada de luz e escuro (12 horas de regime cada). Vale destacar que o regime de 24 horas não afetou em maior grau o crescimento micelial dos referidos isolados quando comparado com o regime de 0 h (escuro), o contrário foi observado Patsa et al (2018), que relataram em seu trabalho ausência de crescimento micelial de B. sorokiniana em condições de luz contínua (24 horas de luz).…”

O objetivo deste trabalho foi avaliar o crescimento micelial in vitro de isolados de Bipolaris bicolor e analisar a produção in vitro de conídios de B. bicolor em diferentes regimes de luz (0 hora, 12 horas e 24 horas) a uma temperatura de 25ºC. Os isolados utilizados para a realização deste trabalho fazem parte da Coleção de fungos fitopatogênicos do Laboratório de Fitopatologia da UEG, Unidade de Ipameri. Os mesmos foram reativados para a realização deste experimento, em meio BDA (Agar Batata Dextrose). Foram avaliados o crescimento micelial, através de discos de micélio que foram avaliados diariamente até o quinto dia após a inoculação (DAI) e para a esporulação, após a última leitura do crescimento radial, as placas foram aproveitadas para quantificação de produção de esporos de B. bicolor. O delineamento experimental utilizado foi o inteiramente casualizado (DIC), com cinco repetições para cada tratamento e os dados foram submetidos à análise de variância e ao teste Scott-Knott (P≤0,05), com o auxílio do software Sisvar 5.6. O crescimento micelial dos diferentes isolados de B. bicolor foi indiferente quanto aos regimes de luz e a produção de conídios de B. bicolor foi superior nos regimes de luz de 12 e 24 h.

“…Laboratory germination was evaluated on a scale from 0 to 3 (Patsa et al, 2018;Kang et al, 2021) where: 0 = 100% germination without signs of seed (root) damage; 1 = 70-99% germination with root damage; 2 = 30-69% germination with fused lesions; 3-0-29% germination when all seed tissues are affected. During the experiment, all samples were regularly examined and recorded.…”

Spring barley is an important high-value crop globally.However, it is highly susceptible to soil-borne diseases in Kazakhstan and the world. Bipolaris sorokiniana (Sacc.) Shoemaker is the most important soil-borne pathogen that causes root rot and spot blotch diseases in cereal crops. This study aimed to evaluate the ability of B. sorokiniana isolated from spring barley leaves to survive in plant residuals of different crops. The fungus was isolated from spring barley leaves from the Zholbarys agro farm of Kerbylak district of Almaty, southeastern Kazakhstan, in 2021. Laboratory experiments were conducted at Kazakh National Agrarian Research University. The study was conducted on 10 th days of seedlings of cereal, legume, and oilseed crops. The obtained results showed that seedlings of spring barley, spring wheat, and oats retained the B. sorokiniana infection. Interestingly, the infection of B. sorokiniana isolated from leaves of spring barley statistically significantly increased symptoms of spot blotch on spring wheat and spring barley seedlings, while symptoms decreased on oats (P-value <0.01). The introduction of rapeseed, chickpeas, peas, and oats into the crop rotation system in southeastern Kazakhstan could limit the volume of the B. sorokiniana infection in spring wheat and spring barley. On rapeseed, peas, and chickpeas seedlings no symptoms of spot blotch were observed (P-value <0.01).
