Turnip and Rutabaga Diseases and Pests
Root vegetables like turnips and rutabagas are prone to a range of threats that can affect their growth and yield. Understanding these diseases and pests is crucial for effective crop management. Let’s dive into the common ones:
Diseases
Bacterial Diseases:
- Black rot: Causes black lesions on leaves, stems, and roots, leading to plant death.
- Soft rot: Results in soft, mushy tissues, often starting from wounds.
Fungal Diseases:
- Alternaria leaf spot: Brown or black spots on leaves, reducing photosynthesis.
- Downy mildew: Yellow or green patches on leaves, weakening plants.
- Phytophthora root rot: Causes root damage, leading to wilting and stunted growth.
Viral Diseases:
- Turnip mosaic virus: Produces mosaic-like patterns on leaves, affecting growth and yield.
- Turnip yellow mosaic virus: Yellowing and stunted plants, transmitted by aphids.
Pests
Aphids: Tiny, winged insects that suck plant juices, transmitting viruses and weakening plants. Cabbage maggots: White, legless maggots that feed on roots, reducing plant growth and yield. Flea beetles: Small, jumping beetles that chew on leaves, causing holes and reducing photosynthesis. Cutworms: Grayish worms that cut seedlings off at the soil line.
Control Strategies
- Crop rotation: Plant turnips and rutabagas in different locations each year to prevent disease buildup.
- Disease-resistant varieties: Choose varieties that are resistant to common diseases.
- Cultural practices: Maintain good soil drainage, water regularly, and remove diseased plant material to minimize disease spread.
- Chemical control: Use fungicides or insecticides as a last resort, following label instructions carefully.
- Integrated pest management (IPM): Combine multiple control methods to manage pests and diseases effectively.
By understanding these diseases and pests and implementing appropriate control strategies, you can protect your turnip and rutabaga crops from damage and ensure a healthy, bountiful harvest.

White rust caused by Albugo candida
Key Takeaways:
- White rust, caused by Albugo candida, affects leaves and flowers of turnips, causing yellow or white spots and blisters.
- It spreads through oospores, or resting spores, found in infected plant material.
- The disease is common in cruciferous crops like rapeseed-mustard, arugula, and rutabagas, leading to significant yield losses.
Prevention:
- Use resistant turnip varieties.
- Practice crop rotation to break the disease cycle.
- Remove and destroy infected plant debris to reduce inoculum.
- Ensure proper drainage to prevent waterlogging, which promotes disease development.

Our exploration promises valuable insights into the art and science of crop protection, empowering growers with the knowledge and tools to safeguard their crops from the perils of disease and pests.
Disease and Pests: Turnip and Rutabaga Diseases
Bacterial Soft Rot:
This nasty bacteria (Erwinia carotovora) loves warm, humid conditions and can swiftly destroy your crop. Keep an eye out for water-soaked spots on roots and leaves that eventually turn into mushy brown lesions.
Blackleg:
Caused by Leptosphaeria maculans, blackleg thrives in cool, wet weather and targets young plants. You’ll spot dark lesions on stems and leaves that can choke the plant, leading to its demise.
Clubroot:
Plasmodiophora brassicae strikes in acidic soils, causing gnarled, swollen roots that are useless. This fungus makes your turnips and rutabagas unpalatable and unmarketable.
Downy Mildew:
Peronospora parasitica prefers cool, wet conditions and attacks the leaves, leaving yellow or brown spots that turn white and fuzzy. This fungus can severely damage your plants.
Prevention and Control
Time to fight back!
- Clean Seed: Use disease-free seeds.
- Crop Rotation: Change your planting location each year to avoid disease buildup.
- Watering and Fertilizing: Keep your plants hydrated and well-nourished for optimal health.
- Resistant Varieties: Choose turnips and rutabagas bred to resist common diseases.
- Early Detection and Removal: If you spot any signs of disease, remove the affected plants promptly to prevent it from spreading.

Clubroot
Clubroot is a soil-borne disease that affects cruciferous plants, including turnips and rutabagas. It’s caused by the slime mold Plasmodiophora brassicae, which forms club-like swellings on the roots, affecting the plant’s ability to absorb water and nutrients.
Key Takeaways:
- Clubroot is caused by the slime mold Plasmodiophora brassicae that survives in soil for extended periods.
- Clubroot affects cruciferous plants like turnips and rutabagas, causing swollen and distorted roots.
- No effective chemical treatments exist for Clubroot.
- Prevention measures are crucial, including crop rotation, resistant cultivars, and proper soil management practices.
Proper prevention techniques, such as crop rotation, selecting resistant varieties, and maintaining soil health are essential for managing Clubroot. If you suspect a Clubroot infection, remove and destroy affected plants promptly to prevent further spread.
