abstract
Sugar beet Armyworm is an important pest of vegetables and other crops throughout the world. Field experiments were conducted to evaluate efficacy of neem oil spray in comparison to pesticide on sugar beet armyworm Spodoptera exigua during 2006-07 and 2007-08 at PARC-NSTHRI farm, Thatta. The armyworm infestation data indicated that minimum average population of armyworm was (1.43 and 0.88) in T-3 followed by (1.65 and 1.07), (1.77 and 1.04) and (1.81 and 1.58) in T-5, T-2 and T-4 respectively as compared control plot (3.64 and 3.58) during 2006-07 and 2007-08. However, from the results of yield, it was observed that T-5 produced significantly higher yield (116.940 and 115.205 t ha^-1) followed by T-3 (115.078 and 112.675 t ha^-1), T-4 (113.666 and 112.687 t ha^-1) and T-2 (110.315 and 110.658 t ha^-1) as compared control plot (68.280 and 68.500 during the year 2006-07 and 2007-08 respectively. Furthermore, the result of sugar content % showed no significant different among treatments. However, the data of sugar yield indicated that maximum (13.250 and 13.052 t ha^-1) yield was observed in T-5 followed by in T-3 (12.993 and 12.766 t ha^-1), T-2 (12.412 and 12.482 t ha^-1), T-7 (8.073 and 7.958 t ha^-1), T-6 (7.850 and 7.824 t ha^-1) and in T-1 control (7.630 and 7.619 t ha^-1) during 2006-07 and 2007-08 respectively.
