The present work was carried out to evaluate the spray quality produced by  two hydraulic ground sprayers using rates of application 113 and 147 L/fed , respectively. Three insecticides were used  Acetamiprid 20% SP. , using a dose rate of  25 gm /100 L. water, neutral Potassium detergent at a dose rate ½  kg / 100 L. water and plant extract Saponins solution at a dose rate one liter / 30 L. water against green peach aphid  Myzus  persicae (Sulzer) on Peach orchard. Data showed that droplet sizes induced by Matabi sprayer with manual pump were bigger than motorized Solo sprayer , however, more coverage homogeneity was obtained by Solo sprayer with a motor pump. Data, showed also that, spray coverage of upper and middle levels of   Peach trees in all treatments reached homogeneity factor 2.5 for hydraulic nozzles according to FAO ,  but  the lower levels of  Peach trees which revealed not homogenous spray. The rate of  Performance (fed / day) for Solo sprayer was 5 fed. / day, while was 3 fed./ day in case of  Matabi sprayer.
Bioassay results indicated that all tested compounds induced negative significant influence   on  Myzus persicae (Sulzer) nymphs survival. Saponins gave promising results in controlling Myzus persiace nymphs on Peach trees with least hazard to emergence rate of natural enemy Parasitoid  Aphidius  matricariae (Haliday) larvae, while Acetamiprid gave the highest reduction in both of Myzus  persicae and  Aphidius matricariae  larvae in case of two sprayers. Data also showed that replacement spray application form high volume spraying to low volume spraying (L/fed); decreases the total operating cost/fed / L. E. , saving spraying time i. e. the rate of performance of  low volume equipment increases, and suitable spray coverage was obtained
