The study was design as RCB with three replications. Three doses of Floramite 500, 600 and 700 ml/1000 lit. of water was compared with Envidor (500 ml/1000 Lit.), Pride (500 ml/1000 Lit.), Ortus (500 ml/1000 Lit.), Danitol (1000 ml/1000 Lit.) of water and check treatment (water spry). Effectiveness of treatments based on mite mortality was calculated and analyzed. The overall effects of pesticides on the day after treatment, respectively, are ranked as follows:' 1- Four days after spraying: Pride (500 ml/1000 Lit.), Floramite (600 ml/1000 lit.), Danitol (1000 ml/1000 Lit.), Envidor (500 ml/1000 Lit.), Floramite (500 ml/1000 lit.), Floramite (700 ml/1000 lit.) and Ortus (500 ml/1000 Lit.) of water. 2- Seven days after spraying: Pride (500 ml/1000 Lit.), Envidor (500 ml/1000 Lit.), Danitol (1000 ml/1000 Lit.), Floramite (600 ml/1000 lit.), Floramite (700 ml/1000 lit.), Floramite (500 ml/1000 lit.) and Ortus (500 ml/1000 Lit.) of water. 3- Fourteen days after spraying: Pride (500 ml/1000 Lit.), Envidor (500 ml/1000 Lit.), Floramite (700 ml/1000 lit.), Danitol (1000 ml/1000 Lit.), Floramite (600 ml/1000 lit.), Floramite (500 ml/1000 lit.) and Ortus (500 ml/1000 Lit.) of water. 4- Twenty-one days after spraying: Envidor (500 ml/1000 Lit.), Floramite (500 ml/1000 lit.), Floramite (600 ml/1000 lit.), Floramite (700 ml/1000 lit.), Danitol (1000 ml/1000 Lit.) Pride (500 ml/1000 Lit.) and Ortus (500 ml/1000 Lit.) of water. 5- Twenty-eight days after spraying: Non significant between all treatments.
