“…Crop residue can intercept up to 80% of the applied pre-emergence herbicide, and this results in the reduced efficacy of the herbicide. This adsorbed herbicide on the residue surface is subjected to various losses such as leaching, photodegradation, and microbial degradation [ 105 ]. The efficacy of prosulfocarb plus metolachlor (3.75 kg·ha −1 ) for the control of E. colona was reduced as biomass increased by 46–70% in the presence of a field equivalent rate of sorghum residue load of 3–6 t·ha −1 [ 96 ].…”

The rice–wheat cropping system (RWCS) has substantially contributed in making India self-sufficient in food grain production; however, rice residue management is of great concern, threatening the sustainability of this system. Rice residue is invariably disposed of by farmers through open burning. In addition to environmental pollution, residue burning of rice also leads to loss of soil nutrients. One of the alternatives to overcome these problems and sustain the RWCS is managing the rice residues in the field itself. Rice residue retention has variable effects on agricultural pests (namely, weeds, insect pests, diseases, and rodents) in the RWCS. High weed infestation in the RWCS results in high consumption of herbicides, which leads to several ecological problems and evolution of herbicide resistance. The shift from intensive tillage to conservation tillage causes major changes in weed dynamics and herbicide efficacy. Incorporation of rice residue reduces weed density and helps in improving soil physical, chemical, and biological properties. Rice residue retention on the surface or mulching reduces weed density and the biomass of both grass and broadleaf weeds in wheat crop as compared to its removal. Long-term field studies involving the use of rice residue as a component of integrated weed management strategies are needed to be done in the RWCS.

“…The majority of the farmers in the north-western IGP burn the residues/straw of rice for the proper seed drilling/sowing of the succeeding wheat crop [8,9]. The burning of straw leads to a remarkable fluctuation in soil temperature that influences germination and the emergence of weeds on the soil surface [8]. However, paddy straw at surface mulch at a rate of 4 and 6 t ha −1 reduced the emergence of R. dentatus by 78 and 88%, respectively, compared to controls (without mulch).…”

“…Nevertheless, the sustainability of the RWCS and national food security is being halted by the emergence of second-generation problems such as the depletion of good quality groundwater [7], the appearance of multi-nutrient deficiency, extensive residue/straw burning [8,9], the emergence of new insects and pests, diseases, declining factor productivity, and an escalating cost of cultivation [4,10]. Furthermore, the adoption of RWCS also led to a shift in weed flora, with the dominance of some of problematic weeds like Phalaris minor and Rumex dentatus.…”

Herbicide resistance in weeds is a global threat to sustaining food security. In India, herbicide-resistant Phalaris minor was the major problem in wheat for more than two decades, but the continuous use of metsulfuron-methyl (an ALS inhibitor) to control broadleaf weeds has resulted in the evolution of ALS inhibitor-resistant Rumex dentatus L. This review summarizes the current scenario of herbicide resistance in R. dentatus, along with its ecology and management perspectives. Studies have provided valuable insights on the emergence pattern of R. dentatus under different environments in relation to tillage, cropping systems, nutrients, and irrigation. Moreover, R. dentatus has exhibited higher emergence under zero tillage, with high infestation levels in rice-wheat compared to other wheat-based cropping systems (sorghum-wheat). Alternative herbicides for the management of resistant R. dentatus include pendimethalin, 2,4-D, carfentrazone, isoproturon, and metribuzin. Although the pre-emergence application of pendimethalin is highly successful in suppressing R. dentatus, but its efficiency is questionable under lower field soil moisture and heavy residue load conditions. Nevertheless, the biological data may be utilized to control R. dentatus. Therefore, herbicide rotation with suitable spray techniques, collecting weed seeds at differential heights from wheat, crop rotation, alternate tillage practices, and straw retention are recommended for addressing the resistance issue in R. dentatus in North India conditions. Overall, we discuss the current state of herbicide resistance in R. dentatus, the agronomic factors affecting its population, its proliferation in specific cropping systems (rice-wheat), and management strategies for containing an infestation of a resistant population.

“…Rice-wheat is the most important cropping system in India. Sustainability issues such as depletion of groundwater, extensive rice residue burning, deterioration of soil structure, accelerated development of wheat associated weeds and escalating cost of cultivation are halting the potential productivity of this system [1,2,3]. The wheat crop is infested by many weeds which includes grasses as well as broadleaf weeds.…”

“…Further, farmers' in northwest India burn both rice and wheat residue in fields resulting in severe losses to ecological health [3]. However, with the development of efficient seeders such as happy seeder, and rotary disk drill, now it is become feasible to drill wheat seed under partial or full rice residue conditions [10].…”

Background: Continuous use of the similar modes of action-based herbicides leads to the development of herbicide resistance in wheat-associated weeds in north-west India. Accelerated development of multiple resistance against most of the available post-emergence herbicides emphasize the use of pre-emergence herbicides. But, the efficacy of pre-emergence herbicide is a matter of concern as surface retained stubbles and/or straw alter herbicide efficacy associated with a direct interception of herbicide. Methods: A field study was conducted for two rabi seasons (2018-19 and 2019-20) to optimize spray volume and time of application for improving the bio-efficacy of pre-emergence herbicides under zero tillage full rice residue scenario. The herbicidal treatments (g/ha) included pendimethalin + pyroxasulfone (1000.0+127.5) as pre-emergence (PE), pyroxasulfone (127.5) as PE, pyroxasulfone (127.5) as early post emergence (EPoE), aclonifen+diflufenican (1002+200) EPoE, halauxifen methyl+ fluroxypyr (7.3+233.4) as EPoE, flumioxazin (100) as PE with two different water volumes 500 and 1000 liter/ha along with pendimethalin fb pinoxaden (1500+50) in 500 l/ha water volume, pendimethalin (1500) as PE in 375 l/ha water volume, weed free and weedy check. Results: The present study showed that pendimethalin + pyroxasulfone as PE with a higher spray volume of 1000 l/ha and alone application of pyroxasulfone as EPoE produced similar Phalaris minor control as with pendimethalin fb pinoxaden (PE fb Post) under full rice residue scenario in zero-till wheat.
