ZARINA; M.A. MAQBOOL Abstract: During a recent survey of phyto nematodes heavy galling of roots of rose (Rosa indica) and kutta grass (Setaria verticillata) growing at the University of Karachi campus was found due to infestation of root knot nematodes.

Abstract: The interaction of different levels of soil salinity on Meloidogyne javanica infecting okra and brinjal was studied in pots with salinity levels of 0.65, 2, 4, 6 and 8 ds m-1.Irrespective of nematisation, reduction in growth characteristics was observed in both the crops whereas interaction between salinity levels and nematode infestation for all the growth parameters was significant. Non inoculated plants had significantly better growth characteristics than inoculated ones. Root-knot index and number of egg masses, increased with increase in salinity levels which in turn increased the nematode reproduction and thereby the damage caused by it.

In J-11, 2 larvae per g of soil was the damaging threshold level, but the nematode reproduction was limited. Rate of nematode multiplication was maximum in PG-1 at the lowest inoculum level. At highest level of inoculation, the population just maintained itself in two cultivars and was less than the initial population in J-11. Out of 500 varieties tested, C-41 (NRCG-31), NCAC-2196 (NRCG-1010), Local 256 and Japtin-220-15 exhibited a resistant reaction against root-knot nematode, M. arenaria.

SEHGAL; H.S. GAUR Abstract: The rate of moisture loss from soil was positively correlated with rate of development, infectivity, and mortality of Rotylenchulus reniformis. Soil moisture tension of 3.99, 25.6, 39.2, and 48.0 bars corresponded to R. reniformismortalities of 32, 47, 52, and 76% respectively. Nematode mortality increased with increasing rates of soil drying. Infectivity of R. reniformis on green-gram (Vigna radiate cv Pusa 105) was also decreased from 49% in fresh samples to 18% in soil layers 3 cm thick. Increasing soil moisture tension also aused a delay of 5-6 days in female oviposition. Mon, 04 Jul 1988 00:00:00 GMT http://localhost:80/xmlui/handle/123456789/17572 1988-07-04T00:00:00Z
