Abstract

Field experiments were carried out in an area of about 2 feddan planted with bean plants variety (Sakha 2 ) Vicia faba (L).during season 2014 in 12th December at Sakha  ,Kafr Elsheikh Governorate. The selected area was split into 7 plots including control plot. Primicarb was sprayed with the rate of recommended and 3/4 recomended dose rate and one treatment left without spraying as control by using Hydraulic Knapsack sprayer (Solo) (22 L./Fed.), Economy Micron ULVA  sprayer (15 L/Fed.) and Conventional motor sprayer (Wisconson) (400 L/Fed.) Data indicated that, all tested doses revealed significant negative influenced on Aphis fabae survival. The most effective is total recommended dose  followed by 3/4 recommended dose. It could be recommended to use these compound with LV spraying equipment with not less than (15L/Fed.).The data showed that Hydraulic Knapsack sprayer (Solo) was the pest equipment to control Aphis fabae on bean plants. The rate of performance of Solo sprayer was 10 Fed./day. It was the best equipment, but the lowest rate of performance was Wisconson motor sprayer since it could spray only 2.5 Fed./day.
