| Abstract | ||
| Laboratory and field experiments along two years (2000 and 2001) were conducled to evaluate the side effecls of six fungicides commercially used namely Antracol, Euparem, Cuprox, Propem, Rizolex and Topsin for controlling disease, on the reproductive potential of cowpea aphid Ap < /em>his crsccivors (Koch) infesting faba bean seedlings. The obtained laboratory results revealed low reduction in the mean number of aphids 6 days after treatment ranging from 10.0610 31.8:1°';,. ~cu,,· •. ;h;le. cata of field experiments showed low reduction for all tested materials in tile first 5 days, but the mean number of aphids increased gradually throughout the experimental period compared with the controt plots and reached 69.64 & ~2 95. 76.36 & 97.52, 80.32 & 102.24, 78.16 &83.16, 72.80 s 95.28 and 55.64 s 74.92 for Rizolex, Antracol, Propem, Euparem, Cuprox and Topsin, for Ihe two years 2000 & 2001, respectively. Topsin was the most favorable fungicide in the presence of aphics giving the highest initial reduction and Significantly the least residual increased rate In aphid population. | ||
