Hand-held and backpack sprayers are ineJ.pensive tools used to apply pesticides on small acreages, Greenhouse, small vegetables field, small orchards, and tree plantations are examples of areas that o.fien require pesticide applications to protect them from weeds, insects, and diseases. Effective pest control dependf on applying the proper amount o.f pesticide. In greenhouse conditions inside are d!(ferent from open field. The conventional sprayers, such as the self-propelled or tractor mounted boom sprayers are not suitable for a greenhouse conditions. The electric developed sprayer was evaluated, and its performance was investigated and compared to Su=uki 2.13 kJV air assist knapsack sprayer. The experiments were carried Ollt at during 201512016 seasons. The developed hydraulic sprayer may able to operate as vertical and hori=ontal boom sprayer. It's able to apply in piper crops in greenhouse and smallfield area ofCabbage (Brassica Oleracea val'. Capitata) under Egyptian conditions. The reslilts showed that the hori=ontal boom set gal'e high value ofdeposition compared to vertical boom set. As well as, , the increasing of operating pressure tends to increase the deposition ,,: values for developed solar sprayer. The deposit spray vallles under open field conditions were 0.1 33pg/cm2 , O. I87pglcm2 and 0.208pglcm2 . The coverage values under open field conditions were 37.8%, 39.1% and 44.5%for 125 kPa, 150 kPa and 200 kPa operating no==le pressures respectively. As well as, the coverage percent values under greenhouse conditions were 27.8 %, 29.7% and 33.8 %for 125 kPa, 150 kPa and 200 kPa operating ncr-=le pressures respectively. The.power consumed was 0.263 kW, 0.289 kWand 0.300 kWat 125 kPa. 150 kPa and 200 kPa respectively. As well as the batte,)' power reduction rate were 0.051 and 0.164 with PV panel charger under small open field and greenhouse l' after one hOllr operating time respectively. ,i Keywords: sprayer, greenhouse, electrical sprayer.
