Effect of pre and post emergence herbicides in rose weed management

Abstract

A field experiment was conducted during 2015-16 to 2017-18 at AICRP on Floriculture, NARP, Pune to study the effect of pre and post emergent herbicide for weed management in rose cv. Gladiator. The experiment was conducted in Randomized Block Design with three replications in seven different treatments. The pooled results revealed that treatment Pendimethalin pre emergence @ 1.0 kg a.i./ha. followed by post emergence ethoxysulfuron 20.0 gm a.i./ha. at 30 DAS and hand weeding at 30 days interval starting from 75 days thereafter significantly minimized the weed biomass in rose and produced maximum plant height (61.30 cm), bud length (4.40cm), flower diameter (5.70 cm), flower stem length (53.40cm), number of flowers per plant (26.06) and vase life (5.60 days) in open cultivated rose.
