Field experiments were undertaken in El - Ismaillia Govemorate, Egypt to evaluate the performance of two ground spraying techniques in greenhouse against whitefly Bemisia tabad (Genn) infesting tomato plants during 2004 & 2005 seasons. Tested spraying equipment were : semco sprayer with hand lance at 6 L/fad. and conventional sprayer at 300 1/fad. with the use of Prempet and jojoba (plant extract) insecticides. Data indicated that semco sprayer with hand lance at 6 L/fad. gave satisfactory coverage on tomato plants amounted 93.75 and 90.7% and minimum lost between plants accounted for 0.59 - 1.48% and very poor contamination on the applicator by 5.66 - 8.14 of spray deposit. But in case of conventional sprayer at 300 L/fad., percentage of spray deposit ranged presented by 42.7 and 34.2% on tomato plants, lost on land between tomato plants was 17.95 and 15.6%, and contamination of applicator reached 47.43 and 41.7%. Data showed that semco sprayer with hand lance at 6 L/fad. gave excellent control against whitefly by using recommended and 3/4 recommended of Prempet insecticide at 300 ljfad. which presented by 80.9 and 67.1%, respectively, followed by jojoba (plant extract) at 500 1/100 litre water with the same sprayer at recommended and 3/4 recommended rates give 68. land 50.3%, respectively. Meanwhile, conventional sprayer gave percent reduction ranged between 59.4 and 56.6 by using Prempet insecticide and 50.1 and 37.4 % with jojoba (plant extract) at recommended and 3/4 recommended respectively.
