NEMA 506 NEMATODE DISEASES OF CROPS                                                                                 (3L+2P) II

Objective
  To know the diseases and their symptoms caused by various plant parasitic nematodes in different field crops, horticultural and plantation crops.

Theory

Causal organism, distribution, host range, biology, nature of damage, symptoms, interaction with other organisms and management of major diseases caused by important nematodes in different crops:

UNIT I
  Cereal crops (Rice, wheat, barley, oat, maize, sorghum): Ear-cockle and tundu disease of wheat, molya disease of wheat and barley; rice-root nematode, root-knot and cyst nematodes, ufra and white tip disease of rice; lesion and cyst nematodes of maize and sorghum.

UNIT II
  Pulses, oilseed, Cash, and fibre crops (Pigeonpea, mungbean, cowpea, chickpea, groundnut, castor, soybean, sunflower, sesame, Sugarcane, sugarbeet, Cotton, jute): Pigeonpea cyst nematode, root-knot, reniform nematodes, lesion, lance nematodes, sugarbeet cyst and soybean cyst nematode problems.

UNIT III
  Vegetable crops (Tomato, brinjal, chillies, carrot, onion, garlic, okra, cucurbits, potato): root-knot disease, reniform nematode, potato cyst nematode; stem and bulb nematode; nematode problems in protected cultivation.

UNIT IV
  Horticultural and Ornamental crops (Citrus, grapes, peach, strawberry, papaya, mushroom, rose, chrysanthemum, zinnia, gladiolus, tuberose, crossandra, jasmine): root-knot disease, reniform nematode; slow decline of citrus, Nematode problems in mushroom.

UNIT V
  Plantation crops & Medicinal and aromatic plants (Banana, pepper, betelvine, coconut, arecanut, palm, cocoa, tea, coffee, rubber, condiments): burrowing nematode infestation in banana, spices and condiments, root-knot and lesion nematodes of coffee and tea, red ring disease of coconut. pine wilt disease.

Practicals
  Study of symptoms of cyst, root-knot, lesion, earcockle, citrus, burrowing, reniform, stem and bulb, white tip, mushroom, leaf and bud, golden nematode damage in different crop plants. Visual field diagnosis of nematode problems through study tours.
