description In the control of bovine worms, biological control by nematophagous fungi stands out, especially <i>Pochoniachlamydosporia</i> which causes the destruction of helminth eggs. This study aims to test the effectiveness of a formulation containing the nematophagous fungus <i>Pochonia chlamydosporia</i> isolated for the biological control of bovine nematodiosis. Twelve cattle were divided into two groups: control group (GC) and the group that received the formulation (GT). Feces and pasture samples were collected for the research of gastrointestinal nematodes. Lung worms and trematodes were investigated. The animals were weighed monthly. The averages of temperature and rainfall were recorded. The supply of the fungus <i>Pochonia chlamydosporia</i> was not effective in reducing the eggs per gram of feces of gastrointestinal nematodes (EPG) of the animals, not differing statistically (<i>p</i> > 0.05) between the groups. The mean values of larvae recovered in the pasture did not differ significantly (<i>p</i> > 0.05). The genus <i>Haemonchus</i> sp. was the most prevalent. There was no correlation between the number of larvae with temperature and rainfall (<i>p</i> > 0.05). There was a statistically significant difference (<i>p</i> < 0.05) in the penultimate weighing of the experiment. The formulation containing <i>Pochonia chlamydosporia</i> was not efficient in the biological control of bovine gastrointestinal nematodes.
