Study on the Efficacy of the Acaricide envidorspeed (SC 24%) (abamectin spirodiclophen) in Comparison with the Common Acaricides against Eotetranychus hirsti

Eotetranychus hirsti is one of the most important pests of rainfed and irrigated fig trees. It is essential to study the effect of new acaricides in the control of this pest. Therefore this experiment was performed in Fars, Markazi, and Kermanshah provinces in randomized complete block design with 4 replications during the summer of the year 2016. Treatments were Envidorspeed (SC 24%) with two concentrations (0.04 and 0.05%), Hexythiazox (EC 10% Nissoron®) (0.05%), Bromopropylate (EC 25% Neoron) (0.15%) and control (water spraying). Results in Fars province show the efficiency percentages on the 3rd day after spraying were 87.82±0.60, 87.47±0.96, 86.19±1.49 and 83.40±1.74 for Envidorspeed (0.04%), Envidorspeed (0.05%), Hexythiazox (0.05%) and Bromopropylate (0.15%), respectively. In Markazi province the results show that the efficiency percentages on the 7th day after spraying were 87.87±0.88, 83.48±0.93, 82.25±1.25 and 81.75±1.80 for Envidorspeed (0.05%), Envidorspeed (0.04%), Hexythiazox (0.05%) and Bromopropylate (0.15%), respectively. In Kermanshah province, on the 14th day after spraying, the efficiency percentages were 99.84±0.05, 99.09±0.32, 98.63±0.44 and 97.26±0.65 for Envidorspeed (0.05%), Envidorspeed (0.04%), bromopropylate (0.15%) and Hexythiazox (0.05%), respectively. Considering the results envidorspeed (0.04%) could be recommended.
