Description A field experiment to study the effects of various pre- and post-emergence herbicides on weed infestation and on corm and cormel
production in three gladiolus( Gladiolus spp.) cultivars was carried out during 1997–2000 at IHBT, Palampur. The main weeds
infesting the experimental farm were Ageratum conyzoides, Gnaphalium peregrinum, Plantago lanceolata, Cynodon dactylon,
Amaranthus viridis, Paspalum dilatatum, Portulaca oleracea, Euphorbia hirta, Oxalis corniculata, Trifolium repens, Imperata
cylindrica and Digitaria adscendance. Of the variouspre-emergence herbicides tested, atrazine and alachlor, both at 1.0 kg a.i./ha,
significantly lowered the germination percentage of the gladiolus cormels. Pendimethalin 1.0 kg a.i./ha reduced the germination of
the cormels to a lesser extent. Pre-emergence application of oxyfluorfen 0.25 kg a.i./ha gave the lowest weed count and weed dry
matter accumulation, comparable with weed free treatment, at 90 daysafter planting (DAP). Thistreatment along with postemergence
application of glyphosate (1.0 kg a.i./ha at 90 DAP) gave best results at 180 DAP. The corm and cormel production was
significantly higher in oxyfluorfen treatment. The results indicate that application of oxyfluorfen as pre-emergence herbicide
followed by application of glyphosate at 90 DAP could be an effective treatment for weed control in gladiolus cormels.
