Multiple field visits were performed to investigate weed flora of wheat fields in Rohtak district of Haryana, conducted during 2018 which revealed infestation of 28 weed species comprising 15 families of grasses and broadleaf weeds.The weeds were identified with the help of available literature and through comparison with the already identified weed species. Poa annua, Polypogon monspeliensis and broadleaf weeds Chenopodium album, Rumex retroflex, Coronopus didymus were the pre-dominant weeds in moist region, whereas Cynodon dactylon, Fumaria parviflora, Chenopodium album,Polypogon monspeliensis in light soil with low salinity.There was a greater variety of weeds in Bohar and Kharawar villages and the least was found in village Sheria and Garnavati from vegetative to fully grown stage.Maximum number of species were of family Poaceae and Asteraceae. This study will be helpful as an additional tool in maintaining the floristic composition of District Rohtak as well as in controlling the weed problem.

“…Shakya et al, (2017) recorded that at25 DAS minimum population of weeds (1.33/m 2 ) was registered in pendimethalin 1.0 kg/ha + metribuzin 0.018 kg/ha in wheat crop. Punia et al, (2017) reported that Sulfosulfuron + metsulfuron 32 g ha -1 was recorded less weed density Phalaris minor 3.9 m -2 and broad leaf weed 2.9 m -2 in wheat field. Devi et al, (2018) reported that application of pinoxaden 50 g ha -1 +RM of carfentrazone and metsulfuron @ 25 g ha -1 recorded lowest total weed density in wheat crop.…”

“…However weeds like Cersium arvense and Convolvulus arvensis are also reported as major weed of wheat growing areas of Punjab and Haryana (Gill and Brar, 1975). In Punjab, the weed flora of wheat consists mainly of grassy weeds like Phalaris minor, Avena ludoviciana and broad leaf weeds like Chenopodium album, Cirsium arvense, Medicago denticulataand Convolvulus arvensis (Singh et al, 1993) (Singh et al, 1995). Weed population of wheat field comprises of complex weed flora (Table 1).…”

Wheat (Triticum aestivum L.) is one of the major cereal food crops of the world and has very important role in attaining food security. Introduction of dwarf wheat varieties coupled with intensive input (assured irrigation and fertilizers) use after Green Revolution led to complex problem of both grassy and broad leaved weeds. Weed management is very important for achieving higher wheat production. Mechanical, cultural, biological and chemical methods can be adopted for weed management in wheat. Due to industrialization, labour is becoming scarce and costly. Among these methods, chemical weed control is more efficient, less costly and less time consuming. Pre-emergence herbicides cannot control the late flushes of weeds especially, grassy weeds. Post emergence herbicides are very effective against weeds in wheat. However, herbicides are effective against some weed groups due to mode of action and they do not kill other weeds. To control other weeds, another herbicide is needed which involves more cost, time and labour. To overcome this, sequential application of herbicides, herbicidal mixtures and herbicidal combinations are used. The herbicidal combinations could be very effective against both grassy as well as broad leaved weeds and help to reduce cost, time and labour. Application herbicidal combinations viz. clodinafop + metsulfuron (vesta) 60 g ha-1, sulfosulfuron + metsulfuron (total) 32 g ha-1 and mesosulfuron + iodosulfuron (atlantis) 14.4 g ha-1 as well as tank mixture of pinoxaden + carfentrazone (50 + 20 g ha-1) is the best way for managing complex weed flora in wheat as of now. Modification in application method like tank mixture with micronutrients also have potential of increasing the weed control efficiency of herbicides and yield of wheat. To give precise and concise information weed management in wheat, his article reviews the latest herbicides recommended for weed management in wheat. Recent advances in herbicidal mixture, combinations and application techniques are also being included in this review.
