In pot trials with sccdlings of Cicer arietinum infected with Meloidogyne jaranica at 1000 lameAg soil, the soil was mixed with necm or datura leaves (200 or 400 ąuintals/ ha), aldicarb or carbofuran 1.5 or 3.0 kg a.i./ha or phorate (3.0 or 6.0 kg a.i./ha). Aldicarb and necm (400 q/ha) were the most efTective in inereasing growth and rcducing galling.

Aldicarb sulphone 75 WP, carbofuran 50 SP, bendiocarb 80 WP and phemamiphos 40 EC were disolved in acetone to produce conccntrations of 0.5, 1.0, 2.0 and 4.0%, and seeds of mung bcan and gram were immersed in the Solutions for 60 sec and then air dried. Carbofuran and bendiocarb at 2 and 4% and phenamiphos at 4% reduced the number of galls of Meloidogyne jaranica on mung 35 days after sowing. Carbofuran and phenamiphos at 1, 2 and 4% reduced the number of galls on gram 42 days after sowing. Nonę of the treatments inhibited germination. Gram seeds treated with acetone alone also showed some reduction in galling.

Aqueosis eatracts from )0, 20, 30 or 40 g neem leaves/ kg of treated soil, were applied to young chickpea plants grown in Meloidogyne javanica infested soil (950 larvae/kg of soil). Plant growtn (shoot and root lcngths, fresh shoot and root weights) were greatest and root galling least with the highest application ratę, with efTects decreasing with a reduction of application ratę.

HeJicotylenchus and Hirschmanniella were present in Iow numbers. In a pot expcriment, Tylencborbynchus, inoculated at 50, 100 and 200/pot, adverscly affected the root: shoot ratio (on dry weight basis). This effect was morę pronounced in the presence of a fungus associated with the field wilt symptom. This fungus delayed emergencc of gram sccdlings.

Sccdlings of 3 chickpea (Cicer arietinum) varieties, B.G.203, H-208 and L-550, were inoculated with 100, 1000 or 10 000 Meloidogyne incognita juvcniles/1000 ml of soil one week after sowing in September, October. November or Decembcr. The maximum reduction in shoot growth was observed following inoculation at the optimum sowing time i.e. October, followed by that observed in September. Sowing in November or Decembcr resulted in little nematode damage. Below an initial inoculum density of 1000 nematodes plant growth was best in October but at higher inoculum densities it was best in the Novcmber sowing. The variety L-550 grew better than the other 2 varieties.

Maize roots rcmaining in the soil after harvest provided a dry season habitat for Pratylenchus spp. (51 adults and 14 juveni!es from 100 g root samples. 4 months after maize harvest). Large numbers of Pratylenchus were found in weed sp^ies. particularly Asonopus compressus, .\maranthus nndis and Commelina nudiflora in Deccmber, February and March. AU motile stages of the nematode were recovered.
