In studies on chemical weed control in cole and cucurbitaceous crops, oxyfluorfen ('Goal') and fluchloralin ('Basalin') proved to be effective herbicides for transplanted cabbage and cauliflower, both in terms of reduced weed dry matter and increased crop yield. For pumpkin, squash and watermelon, butachlor at 2 kg a.i. ha proved to be a suitable herbicide. A significant increase in yield of watermelon was observed using butachlor 2 kg a.i./ha compared with the handweeded control. In bottlegourd, fluchloralin at 2 kg a.i./ha and alachlor and butachlor at 2.5 kg a.i./ha gave better control of weeds compared with the handweeded control. Ridge gourd and bitter gourd tolerated alachlor, butachlor and fluchloralin well. Oxadiazon reduced the yield in ridge gourd. In bitter gourd yield increases were observed with use of alachlor and butachlor at 2 kg a.i./ha, fluchloralin 0.75 kg a.i./ha and oxadiazon at both concentrations. Generally herbicide treatments were found to be more economical than handweeding in most of the crops tested.
