About Purple Blotch Control Products
Purple blotch is a serious fungal disease of onion and garlic caused by Alternaria porri. It starts as small, water-soaked white spots on leaves and seed stalks that grow into sunken, purple-brown lesions with yellow margins and concentric rings. In severe cases, the leaves and stalks dry up and collapse, which reduces bulb size, seed yield and storage quality. The disease spreads fast in warm, humid weather with rain, dew or heavy irrigation. Purple blotch control products are fungicides that stop spore germination, check lesion spread and protect new leaves through the growing season.

Usage Tips for Purple Blotch Control Products
- Start sprays at the first sign of small white or purple spots, or as a preventive spray in humid weather.
- Mix a sticker or spreader with the spray, because onion leaves are waxy and spray runs off easily.
- Cover the leaves and seed stalks thoroughly for good protection.
- Repeat sprays at 10-15 day intervals as per the label, depending on weather and disease pressure.
- Rotate fungicides from different groups to avoid resistance.
- Avoid excess nitrogen and overhead irrigation, which increase disease spread.
- Remove and destroy infected crop debris after harvest.
Types of Purple Blotch Control Products and What They Do?
- Contact fungicides: Form a protective layer on the leaf surface that stops fungal spores from germinating, working best as preventive sprays.
- Systemic fungicides: Are absorbed into leaf tissues and move within the plant, stopping existing infections and protecting new growth.
