ABSTRACT:

The present study is carried out to asses the effect of systemic pesticide triadimefon (WP) on some morpho-anatomical characteristics of cultivar Red Delicious. The parameters studied were leaf area, moisture content, stomatal pore length, width, epidermal cell length, width, stomatal index, trichome length and trichome frequency. The treatment is applied at fruit development stage with different levels ranging (0.00%) to (0.09%). Marked variations were found at the treatment concentration of T3C4 (0.09%) compared to control, however no variation is observed at T3C1 (0.03%) in comparison to control.
