A novel chitosan-cinnamon bead carrier was prepared in this study. Chitosan was mixed with cinnamon powder (CP) and cinnamon extract (CE) to obtain chitosan-cinnamon powder (CCP) beads and chitosan-cinnamon extracted (CCE) beads, respectively. The potential antifungal and nematicidal activities of CCP and CCE were investigated against Rhizoctonia solani and Meloidogyne incognita in vitro. Relative antifungal activity of the CCP (5% CP) bead-treated R. solani was 30.9 and 23.9% after 1 and 2 day incubations, respectively. Relative antifungal activity of the CCE (0.5% CE) bead-treated R. solani was 4.3, 3.0 and 4.2% after 1, 2 and 3 days of incubation. Inhibition of hatch by CCP beads with CP of 5% was 78.8%. Inhibition of hatch by CCE beads with CE of 0.5% was 82.0%. J2 mortality following the CCP (5% CP) and CCE (0.5% CE) bead treatments was 85.0 and 95.8%, respectively against M. incognita after 48 h incubations.

This study investigated whether viable cells, dead cells or cell-free supernatants (CFS) were responsible for the biocontrol effect of strains from two important bacterial genera, and , known for their antifungal properties against plant pathogens and food spoilage microorganisms. Specifically, the capability of these strains to produce extracellular hydrolytic enzymes on specified media was assessed, along with their effectiveness in inhibiting the mycelial growth of several phytopathogenic fungi (, , and ) using dual culture plate assays. Results from these inhibition assays revealed that PF05 and LMG 23520 strains were the most effective in suppressing fungal growth, especially .

The antifungal targets of the new fungicide -(naphthalen-1-yl)-phenazine-1-carboxamide (NNPCN) are still incomplete, limiting its application. To identify potential new targets of NNPCN and facilitate target hunting, a suite of techniques was employed to conduct experiments on . Nine potential targets were identified, exhibiting strong binding affinity to NNPCN, as indicated by binding free energies below -100.

A total of 38 new benzohydrazide derivatives bearing the 4-aminoquinazoline moiety were designed and synthesized based on the active subunit combination approach and tested in detail for their inhibition activities against eight agricultural phytopathogenic fungi. The bioassay results indicated that many of the synthesized compounds exhibited extraordinary fungicidal activities in vitro against the tested fungi. For example, compounds , , , and had EC (half-maximal effective concentration) values of 0.
