        <dc:title>Effects of Soil Solarization on Nematodes Parasitic to&#13;

        <dc:description>Solarization by covering the soil with transparent polyethylene sheets during the summer&#13;
months (April, May, June) in 1984 and 1985 significantly (P = 0.01) reduced the population densities&#13;
of nematodes (Heterodera cajani, Rotylenchulus reniformis, Helicotylenchus retusus, Pratylenchus sp., and&#13;
Tylenchorhynchus sp.) parasitic to chickpea and pigeonpea. Population density reductions of 93% of&#13;
Heterodera cajani eggs and juveniles, 99% ofHelicotylenchus retusus, 98% ofPratylenchus sp., and 100%&#13;
ofR. reniformis were achieved by solarization in 1984. Irrigation before covering soil with polyethylene&#13;
improved (P = 0.01) the effects of solarization in reducing the population densities of Heterodera&#13;
cajani. Similar trends in population density reductions were observed in 1985, but the solarization&#13;
effects were not the same. Nematode population reductions in the 1984-85 season were evident&#13;
until near crop harvest, but in the 1985-86 season the effects on nematode populations were not&#13;
as great and did not last until harvest. Factors such as rains during the solarization, duration of&#13;
solarization, and sunshine hours may have influenced the efficacy of solarization. Solarization for&#13;
two seasons reduced the population densities each year about the same as single season solarization,&#13;
and residual effects of solarization on nematode populations did not last for more than a crop season.</dc:description>
