The present study is carried out to assess the effect of systemic pesticide triadimefon (WP) on physico-chemical features of cultivar Red delicious. The different parameters studied were pedicle, fruit length, width, length : width, total soluble solids (TSS), yield efficiency and average fruit yield. The treatment is applied at fruit development stage with different treatment concentrations ranging from 0. 00 to 0. 09% designed as control (0.00), T3C1, (0.03%), T3C2, (0.05%), T3C3, (0.07%) and T3C4, (0.09%). There is marked reduction in above mentioned parameters at T3C4, (0.09%) compared to control plants. https://www.biotech-asia.org/vol7no1/effect-of-systemic-pesticide-on-physico-chemical-characteristics-of-cultivar-red-delicious/ Pesticides; Red delicious.
