Tetranychus urticae Koch (Acari: Tetranychidae) is a harmful pest for crops such as vegetables, fruits, and ornamental and industrial plants. The usage of plant extracts for pest control is seen as an alternative to synthetic pesticides. The effect of methanolic extracts obtained from sage (S. officinalis) and rosemary (R. officinalis) plants from the Lamiaceae family on T. urticae was researched in an effort to create an alternative to synthetic pesticides. The spray tower-leaf disk method was used to determine the acaricide effects of these plant extracts. The effect of sage and rosemary extracts on the pest's eggs, in nymph and adult stage was examined in the research. Four different concentrations of the plant extracts, which were 1%, 3%, 6%, 12%, were examined. The trials were prepared such that each concentration had 4 repeats and each repeat included 15 individuals. Death-live counts were made on the 1st, 3rd and 6th days. The highest death rates of T. urticae at nymph and adult stages were found at 12% concentrations of sage and rosemary extracts. At this concentration, the death rate for nymph and adults was found to be 79% and 62.2% for sage extract and 58% and 82.2% for rosemary extract. The ovicidal effect of sage and rosemary extracts on pests was determined at the same concentration. As a consequence, sage and rosemary extracts are thought to be used as an alternative method to pesticides for mite control.
