Additionally, the behaviour of acetamiprid, boscalid, bupirimate, cyprodinil, flonicamid, fluopyram, pirimicarb, pyrimethanil, thiacloprid, deltamethrin, and fludioxonil in two apple varieties during four thermal processes ranging betw ...
... Agro-food processing industries generate large amounts of pesticide-contaminated effluents that pose a significant environmental threat if managed improperly. Biopurification systems like biobeds could be utilized for the depuration of these effluents although direct evidence for their efficiency are still lacking. We employed a column leaching experiment with pilot biobeds to (i) assess the depur ...
... Colletotrichum species cause diseases on many plants and are among the ‘top 10’ fungal plant pathogens. Species of the C. gloeosporioides and C. acutatum complexes are particularly important because they infect temperate fruit crops, but their control relies largely on chemical fungicides. In this study, differences in intrinsic fungicide sensitivity were determined in vitro using isolates of the ...
... We determine the exposure of wild birds to pesticides via consumption of fludioxonil-treated winter wheat seeds following autumn drilling. We recorded the density of seeds left on the soil surface, bird density, and consumption of pesticide-treated seed by birds using camera traps. We calculated the dose ingested by each bird species in a single feeding bout and if they ate treated seeds exclusive ...

Abstract:
... Control of grey mould, caused by Botrytis spp., is a major challenge in open field strawberry production. Botrytis was isolated from plant parts collected from 19 perennial strawberry fields with suspected fungicide resistance in the Agder region of Norway in 2016. Resistance to boscalid, pyraclostrobin and fenhexamid was high and found in 89.1%, 86.0% and 65.4% of conidia samples, respectively. M ...
... Dynamics of pesticides decomposition in sweet cherry fruits at different technologies of long-term storage, ultra-low oxygen and modified atmosphere packing, and after post-harvesting application of 1-methylcyclopropen and ozone has been studied. We assumed that type of pesticide and fruit storage conditions may have a profound effect on pesticide residues content. Therefore, levels of residues af ...

Abstract:
... BACKGROUND: Fusarium head blight (FHB) caused by Fusarium graminearum complex (Fg) is a devastating disease of cereal crops worldwide. The succinate dehydrogenase inhibitor, pydiflumetofen, was registered for management of FHB in China in 2019. Previously, laboratory‐induced pydiflumetofen‐resistant (PyR) mutants of Fg have been characterized. However, resistance situation of Fg to pydiflumetofen ...

Abstract:
... Screening green solvents to improve the solubility of insoluble pesticides in water is a significant development direction for pesticide formulations in the future. Amino acid ionic liquids (AAILs) have strong dissolution properties and are widely used in dissolution. In this work, the conductor-like screening model for real solvents (COSMO-RS) as a solvent screening tool was used to screen AAILs ...
... Penicillium digitatum is the most common cause of postharvest decay in citrus fruits around the world. Previous studies revealed that the bZIP gene family plays crucial roles in development, stress adaptation, and pathogenicity in fungi. However, little is known about the bZIP genes in P. digitatum. In this study, we systematically identified the bZIP family in 23 Penicillium species and analyzed ...

Abstract:
... Destruction of pesticides using municipal solid waste (MSW) composting is one of the only rational uses for such waste. Voluminous production of compost featuring high heavy-metal-content, and negative costs of such material, make it possible to inexpensively implement certain large-scale processes at minimal cost. One of these is bioremediation of pesticides which, for various reasons (banned, ex ...

Abstract:
... A selective medium was developed for the isolation and quantification of Fomitopsis meliae (FMS medium), the causal agent of lemon canker and brown wood rot, from plants, soil, and air. The optimal concentration and combination of fungicides and antibiotics was evaluated to determine the most selective condition for growing F. meliae. The resultant composition of the FMS medium per liter (pH 3.5) ...
... In phytopathogenic fungi, the HOG MAPK pathway has roles in osmoregulation, fungicide sensitivity, and other processes. The ATF1/CREB-activating transcription factor Atf1 is a regulator that functions downstream of the HOG MAPK pathway. Here, we identified a gene, designated CsAtf1, that encodes a bZIP transcription factor in Colletotrichum siamense, which is the main pathogen that causes Colletot ...
... Fusarium crown rot (FCR), which is caused by Fusarium pseudograminearum, is one of the most important diseases affecting wheat production in the Huanghuai wheat-growing region of China. Although the phenylpyrrole fungicide fludioxonil is known to have a broad-spectrum activity against a wide range of plant pathogens, including F. pseudograminearum, it has not yet been registered for the control of ...

Abstract:
... Thifluzamide, a succinate dehydrogenase (SDH) inhibitor, possesses high activity against Rhizoctonia. In this study, 144 Rhizoctonia solani AG-4 (4HGI, 4HGII, and 4HGIII) isolates, the predominate pathogen associated with sugar beet seedling damping-off, were demonstrated to be sensitive to thifluzamide with a calculated mean median effective concentration of 0.0682 ± 0.0025 μg/ml. Thifluzamide-re ...
... Early blight, caused by Alternaria solani, and brown leaf spot, caused by a number of small-spored Alternaria spp. including Alternaria alternata sensu stricto, Alternaria arborescens, and Alternaria tenuissima, are observed annually in all midwestern potato production areas. However, Alternaria spp. have developed reduced sensitivity and/or resistance to many single-site mode of action fungicides ...

... Disease caused by Neocamarosporium betae (syn. Phoma betae, Pleospora betae) results in reductions in plant populations, foliar disease (Phoma leaf spot [PLS]), and root disease and decay in table beet. Disease caused by N. betae has reemerged as prevalent in organic table beet production in New York. The disease can also cause substantial issues in conventional table beet production. To evaluate ...
