Abstract
The mean control effectivity of the entomopathogenic fungus M. anisopliae on some forest tree pests has been tested in different works under laboratory and field conditions. To obtain better results in the use of these preparations, compatibility of the fungus under laboratory conditions with some pesticida chemmicals (insecticidas and fungicides) from different groups and formulations were tested. Results showed that the chemmicals tested as concentrated emulsions inhibited considerable fungus development. Equal results were obtained with tose that have systemic action, but contact and ingestion agents showed certain compatibility with the fungus. Results are given in tables and were submited to statistical treatment with a variant análisis and Ducan´s test.
