Onion farming is vital for farmers in states like Maharashtra, Madhya Pradesh, Karnataka,Uttar Pradesh, and Gujarat. However, one of the most common fungal diseases threatening onion yields is Purple Blotch. This disease, caused by the fungus Alternaria porri, can severely impact the health of your crop and reduce both yield and quality. Understanding the symptoms and timely action are key to controlling Purple Blotch and ensuring a successful harvest.
What Is Purple Blotch in Onions?
Purple Blotch is a fungal disease that primarily affects onion plants. The fungus thrives in warm, humid conditions and spreads through infected plant debris, seeds, and water splashes. If left unchecked, Purple Blotch can spread rapidly across the field, causing significant losses.
Symptoms of Purple Blotch
- Lesions on Leaves: Small, water-soaked spots appear on leaves, which gradually enlarge into purplish-brown lesions with yellow halos.
- Drying Leaves: Affected leaves may dry out from the tip downwards, affecting the plant's ability to photosynthesize.
- Weakened Plants: In severe cases, plants may weaken, resulting in poor bulb formation.
- Vulnerable Bulbs: Weak plants are more susceptible to other diseases, further reducing yield.
Economic Loss Caused by Purple Blotch in onion
Purple blotch can cause yield losses of up to 30-50% if not managed promptly, leading to significant economic setbacks. The disease results in smaller, discoloured, and weak bulbs that fetch lower market prices, reducing overall profitability. Additionally, farmers face increased input costs for extra treatments and labour. In major onion-growing regions, these combined impacts can severely affect farmers' financial stability.
