•  
• The texture of these spots can range from slightly raised to sunken areas on the cauliflower.

2. Common Causes:

a) Environmental Factors:

• Exposure to extreme temperatures, such as frost or heat, can cause brown spots on cauliflower.

• Damage caused by hail or heavy rain can also contribute to the development of brown spots.

b) Fungal and Bacterial Infections:

• Cauliflower can be susceptible to fungal infections, such as Alternaria leaf spot or black rot.
•  
• Bacterial infections, like Pseudomonas blight, can also cause brown spots on the vegetable.

c) Physical Damage:

• Rough handling during harvesting, transportation, or storage can lead to bruising, which may result in brown spots.
•  
• Insect feeding or damage from pests can create openings for infections, contributing to spot formation.

II. Prevention of Brown Spots on Cauliflower:

1. Selecting and Storing Cauliflower:

• Choose cauliflower heads that are firm, compact, and have minimal blemishes.

2. Washing and Soaking:
