Title Effects of Soil Solarization on Nematodes Parasitic to
Chickpea and Pigeonpea

Description Solarization by covering the soil with transparent polyethylene sheets during the summer
months (April, May, June) in 1984 and 1985 significantly (P = 0.01) reduced the population densities
of nematodes (Heterodera cajani, Rotylenchulus reniformis, Helicotylenchus retusus, Pratylenchus sp., and
Tylenchorhynchus sp.) parasitic to chickpea and pigeonpea. Population density reductions of 93% of
Heterodera cajani eggs and juveniles, 99% ofHelicotylenchus retusus, 98% ofPratylenchus sp., and 100%
ofR. reniformis were achieved by solarization in 1984. Irrigation before covering soil with polyethylene
improved (P = 0.01) the effects of solarization in reducing the population densities of Heterodera
cajani. Similar trends in population density reductions were observed in 1985, but the solarization
effects were not the same. Nematode population reductions in the 1984-85 season were evident
until near crop harvest, but in the 1985-86 season the effects on nematode populations were not
as great and did not last until harvest. Factors such as rains during the solarization, duration of
solarization, and sunshine hours may have influenced the efficacy of solarization. Solarization for
two seasons reduced the population densities each year about the same as single season solarization,
and residual effects of solarization on nematode populations did not last for more than a crop season.
