Screening of fungicides effective against tomato Nectria blight and determination of their optimal application timing

Key Points

• This study aims to identify effective fungicides and their optimal application timing to control Nectria blight in tomatoes.
• Conducted laboratory and field trials to evaluate fungicide efficacy against Nectria blight
• Tested formulations including pyrimethanil, mandipropamid, fluazinam, ipflufenoquin, and picarbutrazox
• Assessed initial infection rates and disease suppression on wounded tomato plants
• Pyrimethanil, mandipropamid, fluazinam, ipflufenoquin, and picarbutrazox are effective against Nectria blight
• Optimal application timing significantly reduced disease severity in treated plants
• Field testing showed a higher efficacy compared to untreated controls
