of Aphelenchoides sp., Ditylenchus sp., Helicotylenchus sp., Hoplolaimus pararobustus, Macroposthonia
curvata, Paralongidorus bullatus, ScuteUonema clathricaudatum, Telotylenchus indicus and
Xiphinema parasetariae have been associated with groundnut crop growth variability. S. clathricaudatum,
X. parasetariae and T. indicus were widespread and S. clathricaudatum was most abundant
nematode. Population densities of S. clathricaudatum was always higher in the roots of poorly growing,
chlorotic and stunted plants than in the roots of apparently healthy plants. A preplant population
density of 1.3 S. clathricaudatum cm -3 soil caused (p = 0.05) reduction in plant growth of groundnut
cv. 55-437. S. clathricaudatum was mainly confined to 0-15 cm soil depth at the time of planting in June
and was not found below 45 cm depth at any time during the crop growth period. Soil application of
carbofuran (10kg a.i ha -1) reduced the nematode population densities and resulted in vigorous and
uniform crop growth. Higher AI and H-ion concentrations (0.50 meq 100 g-~ soil) also was associated
with poorly growing chlorotic seedlings. Symptoms of nematode-caused variable growth were evident 3
to 4 weeks after seedling emergence.","1992","published",,"Plant and Soil","143","1","Kluwer",,"133-139",,,,,,,,,,,"TRUE",,"0032-079X",,,,,,"","http://dx.doi.org/10.1007/BF00009138 ","http://scholar.google.co.in/scholar?as_q=%22Role+of+Scutellonema+clathricaudatum+in+etiology+of+groundnut+growth+variability+in+Niger%22&num=10&btnG=Search+Scholar&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_ylo=&as_yhi=&as_sdt=1.&","author",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
