摘要

Phalaris minor is the major problematic weed in wheat in the north-western Indo-Gangetic Plains including Punjab and Haryana regions. The accelerated development of herbicide resistance in weed species has narrowed down the chemical options with the wheat farmers for the effective control of weeds. In this regard, a study was conducted with different post-emergence (PoE) herbicides (clodinafop 60 g/ha, fenoxaprop 100 g/ha, sulfosulfuron 25 g/ha, pinoxaden 50 g/ha, mesosulfuron + iodosulfuron 14.4 g/ha, sulfosulfuron + metsulfuron 32 g/ha, clodinafop + metsulfuron 64 g/ha) alone and in combination with metribuzin (105 g/ha) at CCS Haryana Agricultural University, Regional Research Station Uchani, Karnal during 2018-19 and 2019-20. The metribuzin based tank mixed PoE herbicides application resulted in 70-89 weed control efficiency as compared to 17-54 with their application alone, during both the years. The tank mixed metribuzin based PoE herbicides application resulted in effective control of P. minor as well as broad-leaved weeds and also resulted in higher wheat grain yields (5.59 to 5.98 t/ha) when compared to sole application of PoE herbicides (4.18 to 5.19 t/ha). However, soil type, soil moisture and cultivars should be taken in to consideration while using the effective tank-mixed metribuzin based combinations.
