Leveraging deep learning for dollar spot detection and quantification in turfgrass

Crop Science, Volume 65, Issue 1, January/February 2025.
Abstract This study evaluates the effectiveness of fine‐tuning a semantic segmentation model to identify and quantify dollar spot in turfgrasses, the most extensively managed and researched disease of turfgrasses worldwide. Using the DeepLabV3+ model, recognized for its capability to segment complex shapes and integrate multi‐scale contextual ...

Effect of mowing timing and clipping collection practices on azoxystrobin distribution, persistence, and efficacy

Crop Science, Volume 65, Issue 1, January/February 2025.
Abstract Previous research suggests mowing practices following azoxystrobin application alter pest control and residue fate. Azoxystrobin, an acropetal penetrant quinone outside inhibitor fungicide, is commonly applied in turfgrass and other agricultural settings, protecting desired plants from fungal pathogens by inhibiting fungal growth.

Carbon Dots as Bioactive Antifungal Nanomaterials

ChemMedChem, Volume 19, Issue 23, December 2, 2024.
We review the use of carbon dots (CDs) as novel, fluorescent and functionalizable antifungal nanomaterials. After highlighting the features of fungi and the antimycotic mechanisms of CDs, we demonstrated that these nanoparticles could exert antifungal activity by themselves, with promising applications for the development of food packaging materials ...

Blend ratios and mixtures of brown patch susceptible and resistant tall fescue cultivars

Agronomy Journal, Volume 116, Issue 6, Page 2690-2700, November/December 2024.
Abstract Brown patch (Rhizoctonia spp.) is a major disease of turf‐type tall fescue (TF) [Schedonorus arundinaceus (Schreb.) Dumort., nom. cons.]. Many cool‐season turfgrass lawns consist of species mixtures or cultivar blends, but the exact proportion of resistant cultivars in blends and mixtures to effectively reduce disease has not been well ...
