The control efficiency of the nematicides, aldicarb and carbofuran, in the population dynamics of the soybean cyst nematode (Heterodera glycines) was evaluated. Nematode viability, penetration and reproduction were examined in greenhouse experiments. Nematode viability (movement) was greatly reduced by aldicarb, but not by carbofuran. Penetration was inhibited by both chemicals. Percentages of penetration relative to the untreated check 3 days after treatment were 0.4% and 1.7% for aldicarb and carbofuran, respectively. Systemic effects of the nematicides were observed with both nematicides but the effect was greater with aldicarb than with carbofuran. The total effect of the nematicides, applied at the time of planting soybean in infested soil, appeared to be less than the sum of the contact and systemic effects on the initial population dynamics of H. glycines
