%X The use of low-risk mite killers is very necessary to prevent the quantitative and qualitative damage of the Panonychus ulmi in apple orchards. After Tetranychus urticae Koch, Panonychus ulmi Koch has the most diversity of plant hosts on fruit trees, stone fruit trees, fruit trees, non-fruit trees, and weeds in the country. In this research, three concentrations of biphenazit were evaluated against the population of Panonychus ulmi on apple trees in several regions with different geographical conditions and a history of chemical control in apple orchards. Foliar spraying was done by observing the average population of 5 mites and 30% contamination of leaf samples, and the efficiency of each treatment was determined by randomly collecting 50 leaf samples on the upper surface of the leaf. According to the obtained results, concentrations of 6.0 and 7.0 ml/l of biphenazit can be used to start the infection of apple trees with an average of less than 5 European red mites. The obtained results showed that biphenazit reduces the number of natural enemies such as the age bug, predatory mites, and predatory thrips of apple trees, but does not eliminate them.
