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 Azarbaijan-e Sharghi, Azarbaijan-e Gharbi and Khorasan-e Razavi provinces in a randomized complete block design with 7 treatments and 4 replicates. Treatments were the new acaricide, Envidor speed with two dosage, 0.4 and 0.5 ml/L, Baroque 10%SC 0.4 ml/L, Propargite 0.57 EC 1 ml/L , Pride 20% 0.4 ml/L, Envidor 0.24 SC 0.5 ml/lit and a check treatment by spaying water. Mean number of mites per leaf was counted one day befor and 3, 7, 14, 21 and 28 days after spraying. Results showed that both concentrations of Envidor speed were more effective than the other acaricides after 7 days, and this trend continued until 28 days. Envidor speed had better effect with more durability effect on the control of European red mite compared to the other acaricides. We recommend the 0.4 ml/lit dose of this acaricide because of its economic efficiency.
