Implication

Greenhouse trial shows combined dazomet and bio-organic fertilizer suppress Fusarium wilt and restore soil enzymes in monocultured chrysanthemum, suggesting a viable integrated management strategy.

Key Points

To evaluate the efficacy of chemical fungicides, fumigants, antagonistic bio-organic fertilizer, and their combinations in suppressing Fusarium wilt and improving soil biological health in continuous chrysanthemum cropping.
Conducted a greenhouse comparative trial using soil continuously monocultured with chrysanthemum for multiple years.
Assessed five soil treatments: fungicide carbendazim (MBC), fumigant dazomet (DAZ), Paenibacillus polymyxa SQR21-enriched bio-organic fertilizer (BOF), and combinations of BOF with either MBC or DAZ.
Measured Fusarium wilt disease suppression, rhizosphere enzyme activities (urease, catalase, sucrase), bacterial-to-fungal ratios, and microbial community diversity via the Shannon-Wiener index.
All treatments effectively controlled Fusarium wilt, but standalone MBC and DAZ significantly reduced urease activity and failed to enhance catalase activity in rhizosphere soil.
Treatments containing BOF significantly increased soil enzyme activities (urease, catalase, and sucrase) and improved microbial properties, showing higher bacterial-to-fungal ratios and Shannon-Wiener diversity indexes compared to chemical treatments alone.
The combined DAZ and BOF treatment achieved the strongest suppression of Fusarium wilt, maximized soil enzyme activity and microbial diversity, and markedly improved chrysanthemum crop quality.
