Effect of Isoproturon With and Without Adjuvants on Photosynthetic Attributes of Wheat and Its Associated Weeds Planta Daninha
JAVAID,M.M.; ZIA,A.U.H.; WAHEED,H.; NARGIS,J.; SHAHID,A.; AZIZ,A.; WASAYA,A..
ABSTRACT: Among various weed management strategies, chemical weed control is considered the most effective method. However, optimum dose and suitable combination of herbicide with adjuvants play a vital role in controlling weeds at an acceptable level and produce maximum crop yield. A field study was conducted to investigate the effect of post-emergence herbicide isoproturon alone or with combination of adjuvants on winter wheat and its associated weeds. The treatments were isoproturon at 175 g a.i. ha-1, 140 g a.i. ha-1 and 105 g a.i. ha-1 applied alone or with adjuvants Ad-500 or Bio-enhancer at 400 mL ha-1 each and weedy check as a control treatment. Isoproturon at 175 g a.i. ha-1 + Bio-enhancer at 400 mL ha-1 was most effective treatment for control of...

Herbicidal Potential of Sorghum and Brassica Against the Weeds of Cotton Planta Daninha
FAROOQ,O.; ATIQUE-UR-REHMAN,; SARWAR,N.; HUSSAIN,M.; WASAYA,A.; NAEEM,M.; IQBAL,M.M; KHALIQ,A..
ABSTRACT: Weed infestation is among the main factors which decrease cotton yield. Allelopathy has been well-documented as a phenomenon offering natural weed control in agro-ecosystems. An experiment was conducted to figure out the herbicidal potential of a mixture of sorghum and brassica water extracts (SBWE) against weeds in cotton. Combinations of SBWE each at 16 L ha-1 were sprayed alone and in combination in a tank mixed with and ¼ doses of both pendimethalin (0.625 and 0.416 kg a.i. ha-1) and S-metolachlor (1.075 and 0.716 kg a.i. ha-1). Recommended doses of pendimethalin (1.25 kg a.i. ha-1) and S-metolachlor (2.15 kg a.i. ha-1) were also sprayed for comparison. As control, a weedy check treatment where nothing was sprayed was also included in the...
