Abstract

The European red mite, Panonychus ulmi Koch is one of the most important pests of apple orchards in different parts of Iran. The present study was conducted in apple orchards of Esfahan, West Azerbaijan, Alborz and Razavi Khorasan provinces with 11 treatments. Treatments were new brands of  Fenpropathrin, including Patrigol, Rajapathrin, Fenprotex, Ikaros, Danitex, Mactiol and old brands, Danitol (2 ml/L), Broque (0.4  ml/L), Envidor (0.5 ml/lit), and a control treatment by spaying water. Each treatment had four replicates. The percentage of treatment efficiency was calculated by the Henderson-Tilton method. Mean number of mites per leaf was counted one day befor and 3, 7, 14, 21 and 28 days after spraying. Statistical analyses were done using SAS softwares with randomized complete block design in multiple spaces. Results showed that all of the new formulations of Fenpropathrin had a good effect and were effective after 3 days and caused 72 to 98 percent mortality in all four above-mentioned provinces and this trend continued until 7 days (94%). The knock down effect of these acaricides was significant. The efficacy of the compound was up to 93% after 28 days that indicated the persistence of these acaricides. Between these pesticides, Ikaros and Patrigol had the better effects. Ikaros and Patrigol were caused 74-98 % and 55-98% mortality respectively. Based on these results, we recommend the 2 ml/lit dose of the new brands of Fenpropathrin protex for the control of the European red mite in apple orchards.
