Evolution of herbicide resistance in weeds is a serious threat for sustainable crop production. There were reports of poor control of toothed dock (Rumex dentatus L.) with metsulfuron‐methyl herbicide, an acetolactate synthase (ALS) inhibitor used in wheat (Triticum aestivum L.) at farmers’ fields in Northwest India. Two‐year greenhouse and field studies were conducted to (a) determine the level of metsulfuron resistance in toothed dock biotypes collected from farmers’ fields and (b) find effective herbicides for its management. Metsulfuron‐resistant toothed dock biotypes were 6.8‐ to 23.0‐fold less sensitive relative to the susceptible biotype based on resistance index values. Metabolic herbicide resistance is less likely as there was no evidence of involvement of cytochrome P450s those inhibited by malathion. The resistant toothed dock biotypes had a Trp‐574‐Leu amino acid substitution in the ALS gene. Application of premixes such as metsulfuron methyl plus carfentrazone ethyl (5 + 20 g ha–1) and halauxifen plus fluroxypyr (7.3 + 233.3 g ha–1) resulted in effective control of metsulfuron‐resistant toothed dock biotypes in screenhouse and field studies. This first report elucidating the mechanism of resistance to metsulfuron methyl in toothed dock from India will help in devising sustainable weed management approaches.

“…Weed control brought down competition and created congenial micro-environment for better establishment and growth of wheat crop. The herbicide sequence comprising halauxifen + florasulam increased grain yield and its better weed control provided all favourable conditions like increased availability of nutrients, moisture, light and other factors to the crop which in turn resulted in higher dry matter production [55].…”

Weeds are the main biotic obstacles on wheat production, which can impair wheat productivity by up to 60%, if not handled under critical stages of crop life cycle. Chemical weed control through herbicides has been the most popular and effective method among farmers. The weed management using similar herbicides however has led to herbicide resistance in weeds. This requires the evaluation of newer herbicidal combinations for the control of weeds in wheat. Therefore, an experiment was conducted at Research Farm, Department of Agronomy, JNKVV, Jabalpur, Madhya Pradesh during the Rabi season of 2016-17 to evaluate the effect of post emergence application of herbicides on the weeds and yield of wheat. The experiment was laid out in randomized block design with ten treatments comprising of eight herbicidal combinations along with a hand weeding and a weed check and replicated thrice. Observations on different weed parameters, growth parameters and yield of wheat were recorded. Among the different herbicidal combinations, the post emergence application of halauxifen-methyl ester + florasulam at 10.20 g/ha resulted in greatest suppression of weeds and had highest weed control efficiency (56.73%). It also led to highest growth in wheat which resulted in highest grain yield (5.81 t/ha) and harvest index (44.99%). From this study, it can be concluded that the post emergence application of halauxifen-methyl ester + florasulam at 10.20 g/ha can not only control weeds effectively but also increase the yield of wheat.

“…Weeds are principal biotic constraint in crop production and bring severe interference with normal growth, as they compete for resources like nutrients, moisture, light and space and reduces wheat yield by 37-50% (Waheed et al, 2009). Herbicides on account of their selectivity are most important tools in weed management to sustain yield and quality of crop (Mitra et al, 2019). The chemical method of weed control using effective herbicides proved to be more suitable and economically viable.…”

A field experiment was conducted from winter (rabi) 2013–14 to rainy season (kharif) 2015 on sandy-loam soil, to assess the comparative efficacy of different chemical herbicides and their combinations for effective weed control in wheat (Triticum aestivum L.) and their residual effect on succeeding greengram [Vigna radiate (L.) R. Wilczek] crop at Instructional Farm, Sumerpur, Rajasthan. The experiment comprised 9 treatments and the herbicides were applied at 30–35 days after sowing (DAS) as prescribed. The application of sulfosulfuron + metsulfuron methyl @ 32 g/ha recorded significantly lower weed dry matter and weed index along with highest weed-control index (76.73 %). This herbicides combination also resulted in the highest grain yield of wheat (3.82 t/ha) along with highest net return and maximum benefit to cost ratio of the system in the tune of 3.4 : 1 as compared to weedy check. The herbicides failed to influence a significant increase on seed yield of succeeding greengram during kharif seasons in both years. Uncontrolled weed growth throughout the crop growth period caused an average yield reduction of 57% in wheat crop (2.5 t/ha).
