Toba Road, Jhang
Survey of Plant Parasitic Nematodes
Nematodes Population in 5 ml of suspension:
1 2 3 Mean
1363 1332 1468 1388
5 ml of suspension contain Nematodes = 1388
1 ml _____________________ = 1388/5
100 ml ___________________ = 1388/5*100
Total no. of Nematodes in 500gm of Soil= 27760
Total no. Plant Parasitic Nematodes in 100 ml = 523
Helicotylenchus =202 Pratylenchus = 58
Hoplolaimus = 29 Hemicriconemoide = 234
523 no. plant parasitic nematodes contain Hemi.= 234
1 ______________________________ = 234/523
100 _____________________________ = 234/523*100
Hemicriconemoide in sample is = 45 %
Plant parasitic nematodes were identified up to genera level comparing their morphology with the coordination of “ National Nematological Research Centre”(NNRC), Karachi University. But Root knot nematodes were identified up to genera level by studying their morphology and perineal pattern (Taylor and Sasser1978).
Results and Discussion
Table-1 Population of plant parasitic nematodes associated with soils and roots of sugarcane
Table-3 Distribution of Plant Parasitic Nematodes associated with sugarcane
0 = not recorded; + = Present in survey; ++ = Common; +++ = Widespread
Sanitation: Avoid introducing pests to new locations
Crop Rotation: Reducing population in a site by growing a poor
or non host
Heat Therapy: Pasturization and Solarization of soil
Biological Control: Use of Pasturia, Dactyleria brochophaga, Arthrobotrys oligospora
Use of Chemical: Methyl Bromide, Carbofuran @ 8 kg per acre. May be mixed with basal doze of fertilizer at planting time.
