Activity of the novel fungicide SYP-Z048 against plant pathogens

Area of Science:

• Plant Pathology
• Mycology
• Agricultural Chemistry

Background:

• Fungal diseases pose significant threats to crop yields.
• Effective fungicides are crucial for disease management in agriculture.
• SYP-Z048 is a novel chemical entity with potential fungicidal properties.

Purpose of the Study:

• To evaluate the in vitro and in vivo efficacy of the fungicide SYP-Z048.
• To determine the spectrum of activity against various plant pathogenic fungi.
• To assess the fungicidal activity against Monilinia fructicola and its systemic potential.

Main Methods:

• In vitro testing against 18 plant pathogens, including ascomycota, basidiomycota, and oomycota.
• In vitro assays on Monilinia fructicola isolates assessing mycelial growth, germ tube elongation, and sporulation.
• Detached pear fruit assay and field trials for brown rot control.
• Systemic movement assessment using tomato leaf assays.

Main Results:

• SYP-Z048 demonstrated high efficacy against ascomycota and basidiomycota (EC50: 0.008–1.140 μg/ml), with weak activity against oomycota.
• Effective inhibition of Monilinia fructicola mycelial growth, germ tube elongation, and sporulation.
• Showed protective and curative activity against brown rot in detached fruit and field trials, with evidence of systemic movement.

Conclusions:

• SYP-Z048 is a potent fungicide with broad-spectrum activity against key fungal pathogens.
• The fungicide shows significant potential for the management of brown rot and other diseases caused by ascomycota and basidiomycota.
• Systemic properties suggest enhanced disease control capabilities in agricultural applications.
