Abstract

Chemical tests against weeds growing among wheat in south-east Anatolia.

Abstract

The major broad-leaved weeds of wheat in the area are listed, showing the dominant species to be Ranunculus arvensis. Dicurane 500 FW (chlortoluron) early pre-em. gave 95% control of these species as well as of Avena fatua without injuring wheat. Post-em. applications of chlortoluron at 175 g and 200 g/decare gave comparable control but injury to wheat was unacceptable. Broad-leaved weeds were selectively controlled by Faneron 50 WP (bromofenoxim) at 150 g and 200 g/decare; Faneron Combi 50 WP (bromofenoxim [+terbuthylazine?]) at 75 g/decare, applied at the 4- to 6-leaf stage of the weeds, also controlled the broad-leaved species. Avadex BW (tri-allate) at 140 g/decare in 50 litres of water before sowing or at 200 g/decare post-em. controlled A. fatua but higher rates injured wheat.
