Abstract
The effect of Heilaeutyiencinis indicus Siddigi, 1963 and Pratylenchus penetrans Cobb, 1977 Filipjev & Schuurmans Stekhoven, 1941 in single and mixed inoculum levels was studied on growth parameters of Brinjal (Solanum melogena Linn.). The results showed that 100 and 200 inoculum levels singly had non-significant effect on shoot and root length and weight while together they caused significant decrease in shoot and root length at 200 inoculum level.
INTRODUCTION
Brinjal or Egg plant (Solanun: inelo-gena Linnaeus) is commonly cultivated throughout Pakistan (Nasir and Ali, 1985). The fruit is cooked as food while the seeds are used as stimulant. A number of nema-todes have been found associated with Brinjal in Pakistan (Anwar, 1977; Magbool, 1986) but so far no study has been made on the pathogenicity of these nematodes to Brinjal. The present studies were conducted to determine the effect of spiral nematode (Helicotylenchus indices Siddigi, 1963) and root lesion nematodes (Pratylenchus pene-trans Cobb, 1917 Filipjev & Schuurmans Stekhoven, 1941 in single and mixed inocu-lurn
