NEMATODE OF CLUSTER BEAN: 

NEMATODE OF CLUSTER BEAN SUBMITTED BY : KSIAHAN 2008A22BIV SUBMITTED TO: Dr.PURTHI DPRT. OF NEMATOLOGY CCS HAU,HISAR

NEMATODES OF CLUSTER BEAN : 

NEMATODES OF CLUSTER BEAN Root-knot ( Meloidogyne spp. ) Root-lesion ( Pratylenchus spp.) Stubby root ( Trichodorus spp. Cyst ( Heterodera spp .) Reniform ( Rotylenchus reniformis )

SERIOUS NEMATODE: 

Root-knot ( Meloidogyne spp. ) nematodes (RKN) are the most common plant parasitic nematodes that damage fresh market beans SERIOUS NEMATODE

ABOVE GROUND SAYMTOMS: 

ABOVE GROUND SAYMTOMS All plant parasitic nematodes that attack beans cause similar. Plants are often stunted though this rarely occurs uniformly over an area.

ABOVE GROUND SYMTOMS: 

ABOVE GROUND SYMTOMS Nematodes are usually distributed unevenly within a field or garden often resulting in stunted plants in circular or oval patches. Leaves on infected plants are typically pale green to yellow in color. Symptoms are most severe in light, sandy soils. High plant parasitic nematode populations can often result in lower yields. Occasionally the plant dies.

BELOW GROUND SYMTOMS: 

Belowground symptoms of RKN damage appear as galls, knots, or swellings. Galls vary in size from the head of a pin up to ½ inch in diameter on larger roots. Galls cannot be removed as they are comprised of root tissue. Galls on severely infected roots may fuse causing the root system to appear malformed. BELOW GROUND SYMTOMS

PERSISTANCE AND TRANSMISSION: 

Nematodes survive in the soil from year to year and become active as soil temperatures increase in the spring. PERSISTANCE AND TRANSMISSION

CONTROL: 

Use resistant or tolerant varieties. This is the most effective control of root-knot nematode Crop rotation. Rotations with non-host crops is an inexpensive way of reducing damaging levels of nematodes. CONTROL

CONTROL: 

Use a nematode suppressive crop such as marigolds or velvetbean as a rotation alternative. Soil solarization can be effective in sterilizing the soil when environmental conditions are favorable FUMIGATION IN SOIL CONTROL
