Abstract The use of biological agents has been intensified in recent years against eggs and larvae of gastrointestinal nematodes as an alternative control method in pasture plant health management, with the concomitant use with antiparasitic drugs still occurring. The aim of this study was to test the in vitro activity of the following antiparasitic drugs: Ivermectin and albendazole against the following nematophagous fungi: Paecilomyces fumosoroseus, Paecilomyces lilacinus and Paecilomyces variotii. The agar diffusion test was performed using an initial concentration of 0.0016g/mL of each drug, after solidification of the culture medium containing the drug concentration each nematophagous fungi was inoculated. The results showed that in a concentration of 80μg/mL, the fungal growth decreased, however, with the concentration of 160μg/mL, there was no fungal growth in both drugs, compared to the control, which indicates an inhibition in the development of the nematophagous fungi studied when they come in contact with ivermectin and albendazole.
