Summary: SsCak1, a putative protein kinase, is crucial for the growth and pathogenicity of S. sclerotiorum. Deletions in SsCak1 result in developmental defects and complete loss of virulence. Targeting SsCak1 through host-induced gene silencing (HIGS) could be a potential strategy for controlling S. sclerotiorum infection and increasing crop resistance.

Summary: By analyzing the transcriptomes of hyphae and sclerotia, differentially expressed genes related to sclerotia development and pathogenicity were identified, including the up-regulated autophagy-related gene SsAtg1. Further research showed that SsAtg1 plays a vital role in the autophagy pathway, sclerotia development, and pathogenicity in S. sclerotiorum.

Summary: Management of Sclerotinia stem rot disease in Brassica napus heavily relies on fungicides applied at flowering, but the effectiveness is inconsistent. This study found that different B. napus varieties have varying responses to the disease, and the impact of environment is the most influential factor. The research recommends combining long-term and short-term disease outcomes with lesion length measurement for future host screening studies.

Summary: In this study, Clonostachys rosea, a well-known mycoparasitic fungus, was isolated for the first time in India from the sclerotia of the cabbage pathogen Sclerotinia sclerotiorum. One isolate, TNAU-CR 02, showed the highest inhibition of mycelial growth and SEM imaging revealed its ability to destroy the outer cortex layers of sclerotia. Metabolite fingerprinting identified 18 chemical compounds in TNAU-CR 02 and its crude antibiotics showed strong antifungal activity against S. sclerotiorum. Field experiments also demonstrated that foliar application of TNAU-CR 02 effectively reduced disease incidence in cabbage.

Summary: Preconditioning temperature and duration play a role in the germination of Sclerotinia sclerotiorum sclerotia, with no response observed at 4 degrees Celsius and a minimum of 60 days of preconditioning required before significant germination occurs. The highest germination was observed at 50 degrees Celsius. Mycelial compatibility group typing showed significant diversity within and between populations, indicating local adaptation and the ability to respond to seasonal variation.

Summary: Endophytic Paraconiothyrium strains have shown antagonism against Sclerotinia sclerotiorum and promotion of grass growth. Volatile organic compounds produced by these strains inhibit the growth of S. sclerotiorum and promote inhibitory effects on apothecium production. Inoculation of these fungi into seeds of Brachiaria ruziziensis increases biomass, but the strains are sensitive to higher glyphosate doses.

Summary: The FKH protein in the plant pathogenic fungus Sclerotinia sclerotiorum plays an important role in hyphal development, virulence, and sclerotia formation. It is involved in maintaining cell wall integrity and the MAPK signaling pathway. SsFkh1 interacts with SsMkk1 and may function as its downstream substrate.

Summary: This study reveals the important role of SsAGM1 in cell wall synthesis and pathogenicity in S. sclerotiorum. Using RNA interference, it was found that reducing the expression of SsAGM1 significantly decreased the content of chitin and UDP-GlcNAc, leading to the loss of growth and pathogenicity in S. sclerotiorum.

Summary: The necrotrophic pathogen Sclerotinia sclerotiorum is a destructive plant pathogen with a wide range of hosts. Fluxapyroxad, a succinate dehydrogenase inhibitor, exhibited strong inhibitory effect against S. sclerotiorum. Resistance to fluxapyroxad was found to come at a certain fitness cost for the pathogen.

Summary: The aim of this study was to quantify the recovery of Sclerotinia sclerotiorum sclerotia from South African soybean and sunflower silos between 2012/2013 and 2020. The prevalence of recovered sclerotia ranged from 33.3% to 78.3% in soybean production regions and from 9.1% to 95.0% in sunflower production regions. There were significant differences between years for both crops, and variations in the frequency of sclerotia with regard to policy thresholds.

Summary: This study evaluated the baseline sensitivity of Botrytis cinerea to penthiopyrad, a registered fungicide for the management of tomato gray mold (TGM) in China. The resistance of B. cinerea isolates from different regions in Hebei province was also investigated, and four mutation types associated with penthiopyrad resistance were identified. The study revealed the presence of cross-resistance between penthiopyrad and other fungicides, providing important information for the chemical control of TGM.

Summary: Different fungicides and biopesticides showed significant efficacy in controlling Sclerotinia stem rot, reducing disease severity and increasing crop yield. Fludioxonil, boscalid/pyraclostrobin, and fluopyram/prothioconazole exhibited the strongest fungicidal activity against SSR, while Bacillus amyloliquefaciens provided 36% disease control.

Summary: Phytopathogenic members of the Sclerotinia genus, particularly Sclerotinia sclerotiorum, are destructive plant pathogens causing widespread diseases in economically important crops. Control measures for Sclerotinia diseases include cultural practices, crop genetic resistance, chemical fungicides, and biological controls, each with their own benefits and drawbacks. Recent advances and future strategies continue to be developed within these control methods.

Summary: Pesticide-loaded microcapsules with spontaneous deformation on foliar micro/nanostructures are prepared based on biomimetics. The flexibility of the microcapsules can be controlled by adjusting the usage or types of small alcohols in the preparation system. The migration and distribution of small alcohols driven by amphiphilicity affect the interfacial polymerization process, resulting in improved flexibility of the microcapsules. The N-pentanol-loaded microcapsules exhibit strong scouring resistance, sustained release property, and persistent control effect against foliar diseases.

Summary: This study investigated the insecticidal efficacy, accumulation, and dissipation of benzothiazole in grains (wheat, corn, and rice) under different temperatures. A universal detection method was established for benzothiazole residues in three grains. The results showed that the insecticidal efficacy and accumulation/dissipation rate of benzothiazole were influenced by temperature. Corn had the highest insecticidal efficacy, while rice had the highest accumulation and dissipation rate. These findings provide important references for the application of benzothiazole and other fumigants.

Summary: This study investigates the microlevel formation mechanism of microcapsules and proposes a method for regulating the structure of the shells. The results show that enhancing the hydrophilicity of the core enhances the shuttle effect between the oil and aqueous phase, leading to the formation of a loose and thick shell. The thickness and compactness of the shells can be controlled by manipulating the interfacial shuttle effect, which can enhance utilization efficiency and mitigate potential environmental risks.
