Abstract
Two trials were conducled 'or two seasons (1997/98 and 1998/99) at Sids research station (Middle Egypt). One trial with full protection against aphids and another without chemical control, both trials were subjected to roguing and non roguing of diseased plants. A split-plot design with three replications was used. The effect of three sowing dates (25 October, 15 November and 5 December) 011 percentage rate of inrection 0':1 FBNYV in raba been cultivar Giza 429 was studied. Rate of infection increases with delayed sowing. Roguing of diseased plants out of the field was found to be efficient in reducing Ihe rale of Infection wither insecticides was used or nol . Early sowing combined with roguing and chemical spray against aphids was superior to other treatments in reducing the rate of infection reaching only 2.04% COmpared to 44.55% without roguing, chemical control and delayed sowing over twe . season. Using the same cultural practices package in demonstration plots resulted in an inc:ea.se in seed yield of 69% more than thaI of neighboring farmers' fields.
