Abstract :

Most of new acaricides evaluation were demanded against apple mite pest’s orchards in Iran. Effects of flufenzin 200 SC doses (0.2 and 0.3ml/lit) against Panonychus ulmi and Tetranychus urticae in apple orchards of Ardebil, West Azerbaijan, Khorasan Razavi and in Esfahan provinces were investigated during 2014 respectively. Other registered acaricides such as Spirodiclofen 240 SC, bifenazate 24% SC, fenpropathrin 10% EC, fenproximate 5% SC along with1.5% liquid detergent soap, water sprayed in control treatment were used in this study. Random apple leaves sampling at weekly interval followed from middle month of May and by observing mean 5 active mite stages on 30% of the collected leaves, treatments carried out at early morning hours. Efficiency of each treat done by random 40 leaves from middle part of apple trees collected at interval of one day before and 3,7,14, 21 days after treatment respectively. Mean mortality% analysis done by SAS software and ranked them according Duncan method. The higher P. ulmi mortality% by 0.2 ml/l of flufenzin dose treat recorded 92.45% and 95.82% at 3rd and 7th days after in Ardebil and reduced to 55.79% at 21st day respectively. Maximum P. ulmi mortality% caused by 0.3 ml/l of flufenzin dose recorded 86.47% and 81.79% at 14th and 21th days after in Mashhad area and on T. urticae observed between 66.07% to 72.17% during 3rd to 21st days after treatment in Esfahan. Highest mite pest control among registered acaricidal received for spirodiclofen acaricide and effects of all of them in comparison to earliest record found in reduction. Results indicated that by 480 g a.i. of flufenzin spraying in hectare under low mite pest incidence effective control in apple orchard expected.
