Black Rot can be controlled through which method?

Black Rot can be controlled through which method?

• A. Pruning and sanitation
• B. No treatment
• C. Fungicide Sprays
• D. Irrigation management

Answer: (C)

Black Rot on grapes is a fungal disease, so stopping infection where and when spores are most likely to infect is the key. Fungicide sprays provide a protective barrier on leaves and berries during the wet periods when the pathogen is most active, directly preventing spore germination and fungal growth. This makes sprays the most reliable single method to control the disease across a season. Pruning and sanitation reduce sources of inoculum by removing infected material, but they cannot guarantee suppression of new infections everywhere, especially in established vineyards. Irrigation management can help by reducing leaf wetness, but it’s not a stand-alone solution. So, protective fungicide applications are the best control method.
