Abstract
A field experiment was conducted to evaluate the bio-efficacy of UPH 707 against the complex weed flora in grapes during 2008 – 2009. The treatments included test chemicals as UPH 707 and applied @ 250, 500 and 750 g.a.i./ha dosages along with parquat dichloride @ 500 g.a.i./ha; weed check and manually weed control. All the treatments significantly reduced the total number of weeds recorded at 15 and 30 days after treatment over untreated weeds per sq m (3.5, 4.5) and followed by the treatment of UPH 707 at 750 g.a.i./ha (41.5, 29.0), which was found at par with the treatment of UPH 707 at 500 g.a.i./ha (48.5, 44.0) and it was found superior than weed check and parquat dichloride at 500 g.a.i./ha (89.5, 89.0) at 15 and 30 days after application. No phyto-toxicity signs or symptoms were observed at 1, 3, 7, 15, days after application with tested herbicides (UPH-707) at all the dosages including the higher dose of UPH- 707 at 1000 g.a.i./ha. Weed control treatments with or without herbicides significantly increased the number of bunches per vine as compared to weed check. The berry yield was increased with UPH 707 at 750 g.a.i./ha (24.7 t/ha) and this treatment was on par with each other and significantly superior and safe in use over rest of the treatments in grape vineyards.
