A field experiment was conducted at the Isabela substation. The objective of the study was to compare the effect of the fungus P. lilacinus (added 1 week before planting or at planting) and the nematicide carbofuran (1X or 2X) on yields of pepper and on the population fevels of M. incognita and R. reniformis. Significantly more and heavier fruits were obtained from fungus (1 week before planting)-and carbofuran 2X-treated plots than from the check. A similar trend was observed in the nematode population dynamics; although the percentage of nematode reduction was high in all treated plots, it was higher in those treated with the fungus 1 week before planting and with carbofuran 2X.
