Introduction to Brinjal Diseases
  • Brinjal (Solanum melongena) is affected by several major diseases.
  • Diseases reduce yield and fruit quality significantly.
  • Understanding pathogens and symptoms is crucial for effective management.
Little Leaf Disease of Brinjal
  • Pathogen: Phytoplasma, localized in phloem sieve tubes.
  • Symptoms: Small, yellow, soft leaves; shortened petioles and internodes; bushy appearance.
  • Flowers, if formed, remain green; fruiting is rare and fruits are hard, necrotic, and mummified.
  • Spread by leafhoppers (mainly Hishimonas phycitis); survives in weed hosts.
Little Leaf Disease: Management
  • Grow tolerant varieties: Pusa Purple Round, Pusa Purple Cluster, Arka Sheel.
  • Destroy affected plants and eradicate solanaceous weeds.
  • Spray methyl demeton (2 ml/L) or apply phorate granules to soil.
  • Seed dip in tetracycline (10–50 ppm) to reduce infection.
Bacterial Wilt of Brinjal
  • Pathogen: Ralstonia solanacearum, a Gram-negative, motile rod.
  • Symptoms: Sudden wilting, leaf epinasty, yellowing, stunting, vascular browning, bacterial ooze from cut stems.
  • Soil and seed borne; survives in plant debris, wild hosts, and weeds.
  • Spread via irrigation water, infested soil, and contaminated tools.
Bacterial Wilt: Favourable Conditions and Management
  • Favoured by high soil moisture and temperature.
  • Resistant varieties: Pant Samrat, Arka Nidhi, Arka Neelakantha, Surya, BB 1, 44, 49.
  • Crop rotation with non-solanaceous crops; green manuring with Brassica spp.
  • Soil solarization (125 μm polyethylene, 8–10 weeks); biological control with Pseudomonas fluorescens, Bacillus spp.
  • Seed and soil treatment with antagonistic P. fluorescens; seedling dip before transplanting.
Phomopsis Fruit Rot (Phomopsis Blight)
  • Pathogen: Phomopsis vexans (asexual stage), Diaporthe vexans (sexual stage).
  • Attacks all growth stages; most destructive on fruits.
  • Symptoms: Damping-off in nursery, collar rot, leaf spots with pycnidia, stem cankers, sunken fruit spots, soft rot, mummified fruits.
  • Pathogen is seed-borne and survives in plant debris as mycelium and pycnidia.
Phomopsis Fruit Rot: Epidemiology and Management
  • Disseminated by rain splash, irrigation water, tools, and insects.
  • Favoured by high humidity, temperatures around 26°C, and wet weather.
  • Management: Remove crop debris, crop rotation, use disease-free seed.
  • Hot water seed treatment (50°C, 30 min); seed treatment with thiophanate methyl (1 g/kg).
  • Spray thiophanate methyl or carbendazim (0.1%) at 20-day intervals.
Cercospora Leaf Spot of Brinjal
  • Pathogen: Cercospora melongenae and related species.
  • Symptoms: Large, brown to grayish-brown circular or irregular leaf spots; coalescence leads to premature leaf drop and fruit rot.
  • Fungus survives in soil debris and infected seeds.
  • Favoured by high humidity, warm days, cool nights, and persistent dew.
Cercospora Leaf Spot: Management
  • Destroy crop debris; practice crop rotation and use disease-free seeds.
  • Maintain wider plant spacing to reduce humidity.
  • Spray zineb (0.25%), carbendazim (0.1%), or thiophanate methyl (0.1%) at 10–14 day intervals after disease onset.
Summary: Integrated Disease Management in Brinjal
  • Use resistant/tolerant varieties and certified disease-free seeds.
  • Practice crop rotation, field sanitation, and weed management.

Summary

Eggplant (Solanum melongena), commonly known as aubergine in British English and brinjal in South Asia, is a member of the nightshade family Solanaceae, cultivated for its edible fruit, which is often purple. This plant species has a rich history of domestication, primarily in the Old World, and is a significant vegetable crop in countries like India, Japan, and the USA. Eggplant exhibits great morphological diversity and is categorized into three botanical varieties based on fruit shape: round, long slender, and small miniature types. Cultivation focuses on breeding for high yield, quality, disease resistance, and consumer-preferred traits, while also addressing issues like solanine toxicity and pest resistance. Notable pests include the eggplant fruit borer, and breeding methods include pureline selection and
