The occurrence of postharvest kiwifruit rot has caused great economic losses in major kiwifruit-producing countries. Several pathogens are involved in kiwifruit rot, notably Botryosphaeria dothidea, and Diaporthe species. In this study, a recombinase polymerase amplification (RPA) assay was developed for the rapid and sensitive detection of the pathogens responsible for posing significant threats to the kiwifruit industries. The RPA primer pairs tested in this study were highly specific for detection of B. dothidea and D. eres. The detection limits of our RPA assays were approximately two picograms of fungal genomic DNA. The optimal conditions for the RPA assays were determined to be at a temperature of 39°C maintained for a minimum duration of 5 min. We were able to detect the pathogens from kiwifruit samples inoculated with a very small number of conidia. The RPA assays enabled specific, sensitive, and rapid detection of B. dothidea and D. eres, the primary pathogens responsible for kiwifruit rots in South Korea.

As the world's largest producer of kiwifruit, China faces significant yield and quality losses due to the widespread occurrence of kiwifruit root rot. To explore alternative biological control strategies for kiwifruit root rot, this study isolated 11 fungal isolates from diseased kiwifruit roots and identified as the primary pathogen. Additionally, a biocontrol strain, C3, was isolated from the rhizosphere of healthy kiwifruit and shown to significantly inhibit pathogen growth.

is the main cause of soft rot in kiwifruit, significantly reducing both yield and quality. While chemical treatments are commonly used, their effectiveness is limited and they may pose environmental risks. As a result, biological control using Bacillus species has emerged as a promising alternative.

Smart pesticide delivery systems that respond to pathogen-specific enzymes represent a sustainable and targeted approach for managing postharvest diseases. In this study, we developed a pectinase-responsive nanoplatform (CYM@MOF@pec) by encapsulating cymophenol (CYM) within aminated metal-organic frameworks (UiO-66-NH₂), followed by surface coating with pectin as a bioactive gatekeeper. The resulting nanoparticles exhibited a uniform spherical morphology with an average diameter of 242 nm and a drug loading efficiency of 15.

Fungal diseases significantly affect the quality and safety of food and agricultural products. Pyrimidine ether compounds have shown effectiveness as commercial antifungal agents, but their prolonged or excessive use has led to resistance and pesticide residue issues, necessitating structural modifications. In this study, ferulic acid served as a framework for synthesizing a series of derivatives by introducing pyrimidine and amide groups.
