Summary: Fusarium head blight (FHB), caused by F. graminearum, is a destructive disease for cereal crops, particularly wheat. Fludioxonil, a phenylpyrrole fungicide, has been registered for FHB control in China due to its excellent activity against F. graminearum. In this study, six fludioxonil-resistant isolates were identified from wheat fields in three provinces of China. These resistant isolates exhibited fitness defects and reduced glycerol accumulation compared to sensitive isolates. Importantly, there was no cross-resistance observed between fludioxonil and other fungicides. The mutations in different domains of FgOS1, FgOS2, or FgOS4 were found in the resistant isolates. This study provides valuable insights into the biological and molecular characteristics of field isolates of fludioxonil-resistant F. graminearum, which can contribute to the development of effective strategies for FHB control.

Summary: This study evaluated the impact of fungicides on head blight disease, spike harvest index, and DON accumulation in wheat kernels. The application of fungicides containing tebuconazole, thiophanate methyl plus tetraconazole, and prothioconazole plus trifloxystrobin reduced the disease severity and increased kernel weight. The efficacy of tebuconazole and prothioconazole plus trifloxystrobin was higher than that of thiophanate methyl plus tetraconazole.

Summary: Through studying 496 barley accessions, it was found that the UGT13248 gene plays a role in resistance to Fusarium head blight (FHB) by converting DON to D3G, a nontoxic form; two mutant alleles (T368I and H369Y) were identified that increase FHB severity and reduce D3G production.

Summary: Fusarium head blight (FHB) caused by fungi of the genus Fusarium is a severe crop disease that leads to significant economic losses in major cereal production. Different regions in Poland showed varied levels of contamination by Fusarium species, with warmer regions being colonized mainly by F. graminearum and high levels of deoxynivalenol (DON), while cooler regions had predominance of Fusarium species typical of cold climates. The severity of grain infection with certain Fusarium species was found to be affected by mean daily temperature and high humidity in May, with competitive interactions observed between different genotypes of Fusarium species.

Summary: This study isolated and identified an endophytic bacteria called Pseudomonas poae, which showed strong antifungal activity against the Fusarium graminearum pathogen. The bacteria were able to inhibit the growth of the pathogen and promote the growth of wheat plants through various mechanisms. Therefore, this strain can be used as a biopesticide alternative to synthetic chemicals for protecting wheat from fungal infection.

Summary: This study investigates the interactions between two priming solutions, calcium (Ca) or salicylic acid (SA), and F. graminearum inoculation on wheat seedlings' growth, physiological attributes, and molecular responses. The results show that F. graminearum inoculation reduces growth rate and chlorophyll content, but increases carotenoids, stress markers, antioxidant molecules, osmolytes, and the activity of antioxidant enzymes. However, pre-soaking wheat kernels in Ca or SA solutions mitigates the negative effects of fungal inoculation and restores growth, chlorophyll content, and antioxidant capacity.

Summary: The epidemiology of Fusarium Head Blight (FHB) in spring barley was assessed in this study. Soil and spray inoculation were used to increase disease pressure and provoke genotypic differentiation. The evaluation of stable quantitative FHB resistance in barley genotypes was achieved through the quantification of fungal DNA contents and multiple Fusarium toxins. The study also identified the impact of weather conditions on fungal colonization in mature barley grain.

Summary: The discovery of novel structural models is crucial for agrochemical innovation. In this study, scaffold hopping was performed to synthesize and evaluate 16 novel models. Among them, oxazolyl-oxazoline 25 showed promising antifungal potential against Fusarium graminearum and could effectively inhibit the carbendazim-resistant strain.

Summary: Fusarium is a genus of plant pathogens that can cause diseases such as Fusarium head blight and Fusarium wilt. These pathogens produce mycotoxins that are harmful to crops like wheat, barley, and maize. Silencing essential genes through host-induced gene silencing (HIGS) has proven to be an effective control strategy for reducing mycotoxin production in Fusarium species.

Summary: Research identified that DON toxin production by F. graminearum during infection of small grain crops is a major contributor to economic losses. A novel strain of Fusarium graminearum virus 1 (FgV1-SD4) was discovered, which showed reduced virulence of F. graminearum against wheat and decreased DON accumulation in infected seeds. This mycovirus strain and specific genetic components of FgV1-SD4 could be further optimized as a biocontrol agent to reduce Fusarium head blight and DON accumulation in small grain crops.

Summary: The ability to manipulate gene expression of Fusarium spp. via RNAi offers new possibilities for disease control. In this study, VIGS and SIGS were used to silence the TRI5 gene in F. culmorum, resulting in reduced aggressiveness on spring wheat. The experiments showed that dsTRI5RNA treatment significantly decreased toxin accumulation and downregulated TRI5 expression, while VIGS and SIGS techniques reduced the proportion of infected wheat.
