Diseases

Name of the diseases	Symptoms & management
Alternaria Leaf Blight (Alternaria dauci)	Symptoms: Brown to black spots on leaf margins with yellow halo. Management: Spray Carbendazim 12% + Mancozeb 63% @ 2 g/litre. Use certified, disease-free seed. Avoid excess irrigation.
Powdery Mildew	White powdery cottony growth on the leaves, severe cases lead to defoliation. Control: Carbendazim (1ml/litre of water) or Karathane (0.5 ml/litre of water), Tebuconazole 50% + Trifloxystrobin 25% @ 0.5 gm/ltr or Meptyl dinocap @ 0.5 gm/ltr.
Rhizoctonia	Horizontal cracking of roots leading to rotting and other secondary fungal infections. Control Measures: Carbendazim @ 1 gm/ltr, Capton 70% + Hexaconozole 5% WP @ 2 gm/ltr.
Cottony rot / Sclerotinia rot	White cottony mold on roots, especially during storage. Control: Capton 70% + Hexaconozole 5% WP @ 2 gm/ltr.
Bacterial Soft rot	Wilting of the foliage, water-soaked lesions on the roots, leading to rotting with a foul smell. Control: COC 2 gm/ltr, K-Cycline 0.5 gm/ltr.

Pests

Name of the pests	Symptoms & management
Aphids	Suck the sap from lower leaves of the plant causing misshapen leaves. Control: Acephate 75% SP (1g/L), Imidacloprid @ 0.25 ml/ltr.
Carrot Rust Fly / Root Maggot	Dam aged the roots by boring into them. Causes extensive damage and secondary root infection. Control: Apply chlorpyrifos 20 EC @ 2 ml/litre mixed with sand and apply to the entire field.
Root Knot Nematode	Formation of nodules in the roots, affecting root formation. Control: Fluensulfon 2% G, @ 5 Kg/Ha (method of application: Broadcasting).

Harvesting

75 to 80 DAS (Days After Sowing).

Yield

60-65 tons/Ha

Disorder / Symptom	Symptoms & Management
Forking of Roots	Roots divide into two or more branches. Management: Use deep, loose soil. Apply well-decomposed FYM only. Maintain proper spacing and avoid water stagnation.
Cracking of Roots	Vertical splits on roots, especially near maturity, caused by excess nitrogen and high moisture. Management: Avoid excess nitrogen and irrigation. Apply borax @ 10 kg/ha once during field preparation.
Greening of Crown	Top part of root turns green. Management: Earth-up (cover soil) around root zone at 30–40 days after sowing.
Anthocyanin Pigmentation	Due to moisture stress. Management: Maintain proper irrigation schedules.
Necking (Cucurbits)	Due to improper pollination or poor management. Control: Improve Honeybee/pollinator activity in the field. Use standard package of practices.
Hollow Heart (Cucurbits)	Cavity within the fruit affecting texture and marketability. Control: Avoid excess nitrogen and apply Multinutrient mix @ 12 Kg/Ha.
Fruit Cracking (Cucurbits)	Cracks caused by rapid changes in water uptake or stress. Control: Proper irrigation management.
Light Belly Color (Cucurbits)	Under surface of fruit remains light instead of turning dark green. Control: Follow staking method. Remove lower leaves about 2 feet height to increase aeration and sunlight.
