... Detection of the Fusarium head blight (FHB) is crucial for wheat yield protection, with precise and rapid FHB detection increasing wheat yield and protecting the agricultural ecological environment. FHB detection tasks in agricultural production are currently handled by cloud servers and utilize unmanned aerial vehicles (UAVs). Hence, this paper proposed a lightweight model for wheat ear FHB detec ...

Abstract:
... Object segmentation in deep learning has been recently used for the detection of Fusarium head blight (FHB), a worldwide disease in wheat. Such method, however, cannot detect the disease with high accuracy and is difficult to be used in labelling annotation. However, object detection network can solve the above problem. The object detection network has high detection accuracy and easy for labeling ...

Abstract:
... BACKGROUND: Fusarium head blight (FHB) caused by Fusarium graminearum is a devastating fungal disease of wheat. The mechanism underlying F. graminearum-wheat interaction remains largely unknown. tRNA-derived fragments (tRFs) are RNase-dependent small RNAs derived from tRNAs, and they have not been reported in wheat yet, and whether tRFs are involved in wheat-F. graminearum interactions remains unk ...

Abstract:
... The present study reports the species identification of Fusarium isolates infecting Durum wheat cultivated in Algeria. Characterization of isolates was initially carried out based on morphological criteria and further confirmed by molecular studies. Molecular identification was performed by PCR assays using species-specific primers. The results showed that more than 40% (3/7) of the isolates belon ...

Abstract:
... Wheat kernels damaged by Fusarium head blight (FHB) lose moisture, protein and starch and carry dangerous toxins. Classification of degree of damage can be helpful to customise the use of wheat kernels, reduce financial losses and ensure grain safety. In this study, hyperspectral imaging (HSI) and deep learning network were explored to determine sound, mildly, moderately and severely damaged wheat ...

Abstract:
... The recognition accuracy of traditional image recognition methods is heavily dependent on the design of complicated and tedious hand-crafted features. In view of the problems of poor accuracy and complicated feature extraction, this study presents a methodology for the estimation of the severity of wheat Fusarium head blight (FHB) with a small sample dataset based on transfer learning technology a ...

Abstract:
... KEY MESSAGE: The effect of the Rht1-genes on FHB resistance depends on anther extrusion and level of background resistance. Qfhs.ifa-5A increases resistance and anther extrusion as efficiently as semi-dwarfing alleles decrease it. The semi-dwarfing reduced height alleles Rht-D1b and Rht-B1b have been deployed in modern wheat cultivars throughout the world, but they increase susceptibility to Fusar ...

Abstract:
... Creating new genetic variation by crossing two or more parents is the initial and often most important step when developing new crop varieties. Hence, several mate selection indices have been suggested to support the planning of crosses in genomic breeding pipelines that have been established in many breeding programmes in recent years. The corresponding index weights are however difficult to dete ...

Abstract:
... Detection of infected kernels is important for Fusarium head blight (FHB) prevention and product quality assurance in wheat. In this study, Raman spectroscopy (RS) and deep learning networks were used for the determination of FHB-infected wheat kernels. First, the RS spectra of healthy, mild, and severe infection kernels were measured and spectral changes and band attribution were analyzed. Then, ...

Abstract:
... Reduced height (Rht) genes are widely used in modern wheat breeding although some confer higher susceptibility to Fusarium head blight (FHB) caused by F. graminearum and other species. Our objective was to test whether the recently identified Rht24b dwarfing allele has a neutral effect on FHB response as reported previously from a single mapping population when unrelated winter wheat cultivars wer ...

Abstract:
... Because Fusarium head blight (FHB) intensity is usually highly variable within a plot, the number of spikes rated for FHB index (IND) quantification must be considered when designing experiments. In addition, quantification of sources of IND heterogeneity is crucial for defining sampling protocols. Field experiments were conducted to quantify the variability of IND (“field severity”) at different ...

Abstract:
... Fusarium spp. are phytopathogens causing fusarium head blight in wheat. They produce mycotoxins, mainly fumonisins, deoxynivalenol, and zearalenone. The study was conducted during two growing seasons (2020 and 2021) at the experimental field and laboratories of the Hungarian University of Agriculture and Life Sciences (MATE). The aim of the study was to determine the influence of growing season, n ...

Abstract:
... Fusarium head blight (FHB) disease reduces wheat yield and quality. Breeding wheat varieties with resistance genes is an effective way to reduce the impact of this disease. This requires trained experts to assess the disease resistance of hundreds of wheat lines in the field. Manual evaluation methods are time-consuming and labor-intensive. The evaluation results are greatly affected by human fact ...

Abstract:
... Fusarium head blight and the contamination of cereals with toxic fungal metabolites are particularly important problems in global agriculture. The increasingly frequent isolation of F. equiseti from cereal grain and the sparse information in the literature on the harmfulness of this fungus to oat encouraged us to conduct the present research. The aim of the study was to determine the susceptibilit ...

Abstract:
... Biotic and abiotic plant stress (e.g., frost, fungi, diseases) can significantly impact crop production. It is thus essential to detect such stress at an early stage before visual symptoms and damage become apparent. To this end, this paper proposes a novel deep learning method, called Spectral Convolution and Channel Attention Network (SC-CAN), which exploits the difference in spectral responses ...

Abstract:
... Fusarium avenaceum is a filamentous fungus commonly associated with plants and soil. It is a causal agent of Fusarium head blight (FHB) on maize and small-grain cereals and blights on other plant species, and is one of the very few fungal species known to have ice nucleation activity (i.e., it catalyzes ice formation). Here, we report the draft genome of the ice-nucleation-active F. avenaceum stra ...

This report documents FHB epidemics on soft red winter wheat in Georgia in 2018 and 2019. Forty-four wheat fields across 23 counties were assessed for FHB incidence (2019 only), Fusarium-damaged kernel, deoxynivalenol (DON) contamination, and thousand-kerne ...
... Fusarium head blight (FHB) is a devastating fungal disease of small grain cereals including wheat. Causal fungal agents colonize various components of the field during their life cycle including previous crop residues, soil, and grains. Although soil and residues constitute the main inoculum source, these components have received much less attention than grains. This study aimed at disentangling t ...
