Description An investigation entitled, "Efficacy of new herbicides in controlling weeds in wheat with special reference to Phalaris minor" was conducted during Rabi 1998-99 at the experimental Farm of Regional Agricultural Research Station, R.S.Pura (Jammu). Twelve treatments comprising Topik (333 and 400 g ha-1), Pumasuper (600 and 800 g ha-1) Sulfosulfuron (26.6 and 33.3 g ha-1) , Sencor (200 and 250 g ha-1) . Grasp (3500 g ha-1), Isoproturon (1000 g ha-1) , weed free and weedy check were tested in a randomizeci block design with 3 replication. Phalaris minor Retz., Medicago denticulata, Auagallis arvensis L., Fumaria parviflora L., Lathyrus aphaca L. and Vicia sativa L. were the predominant weeds present in the experimental field. The study revealed that all the weed control treatments except isoproturon (1000 g ha-1) were found to be equally effective in reducing the dry matter of Phalaris minor and were at par with each other. Whereas, isoproturon (1000 g ha-1) reduced the dry matter of Phalaris minor significantly as compared to weedy check. The dry matter accumulation of broad leaved weeds was reduced significantly by weed free and Sencor (200 and 250 g ha-1), as compared to the rest of weed control treatments, hence proved to be best treatments for effective control of Phalaris minor and other broad leaved weeds in wheat. Similarly, the grain yield was also significantly highest in weed free and Sencor (200 and 250g ha-1) treatments. Isoproturon (1000 g ha-1) was next in superiority in controlling broad leaved weeds and produced statistically higher grain yield than remaining treatments. Application of Sulfosulfuron (26.6 and 33.3g ha-1) indicated significant reduction in grain yield of wheat as compared to weed free, Sencor (200 and 250 g ha-1) and isoproturon (1000 g ha-1) due to lesser control of broad leaved weeds. However, Topik (333 and 400 g ha-1) , Pumasuper (600 and 800 g ha-1) and Grasp (3500 g ha-1) remained completely ineffective against broad leaved weeds and recorded significantly lower grain yield than other weed control treatments.
