“…Depending on the related weed species, their density, the length of crop weed competition, etc., and their cumulative effect of decreased crop production, weeds caused significant damage to the crop. These findings are consistent with the findings of Kamble et al 2017 [2] and Khedkar et al 2009 [3] .…”

The BSP Unit, Department of Agronomy, JNKVV, Jabalpur (M.P.) performed a field experiment in Kharif 2019-20 in Randomised block design (RBD) with three replications was used to arrange the 11 herbicidal treatments that made up the study. The study revealed that highest seed yield (1811 kg ha -1 ) and the greatest harvest index (36.1%) were found under Diclosulam 0.9% + Pendimethalin 35% SE 22.5 + 875 g ha -1 , respectively, demonstrating a significant superiority over other herbicide mixtures when applied as a PPI. The control plot had the lowest protein value (40%). Whereas, applying Diclosulam 0.9% + Pendimethalin 35% SE 22.5 + 875 g ha -1 (41.90%) and Diclosulam 0.9% + Pendimethalin 35% SE 45 + 1750 g ha -1 (41.70%) had the highest protein content, respectively. With the exception of hand weeding plots, no herbicide treatment outperforms hand weeding twice, making it noticeably better than all other treatments.

Aims: To identify the weed species in Bt cotton under Tunga-bhadra project command area and to study the effect of sequential application of pre- emergent (PE) and post- emergent herbicides (PoE) on weed growth and to know the efficiency of different weed control practices on weed species. Study Design: The experiment was laid in RBD (Randomized Block Design). Place and Duration of Study: The experiment was conducted at ICAR- Krishi Vigyan Kendra farm, UAS, Raichur situated in TBP command area during kharif season of 2018-19. Methodology: The design was RBD with 11 treatments and replicated thrice. Gross plot size of the field was 7.2 m × 4.8 m and net plot size was 5.4 m ×3.6 m with spacing of 90 x 30 cm. The certified seeds of Jadoo Bt II Cotton with the test weight of 6.5 g was used for sowing. The crop duration was around 6 month Results: Weed flora present in the Bt cotton field were identified and classified based on their morphology. It was divulged that; dicotyledonous weeds were dominant in cotton field. The sequential applications of metolachlor 50 % EC @ 1000 g a.i. ha-1 as PE fb pyrithiobac sodium 10 EC @ 125 g a.i. ha-1 as PoE @ 2-5 leaf stage of weeds fb Inter cultivation (IC) @ 60 DAS reported lower weed count and weed dry matter and reported the highest weed control efficiency (90.22 %) at harvest than the application of diuron 80 % WP as PE fb @ 1500 g a.i. and pendimethalin Pendimethalin 30 EC @ 1250 g a.i. ha-1 as PE followed by pyrithiobac sodium 10 EC @ 125 g a.i. ha-1 as PoE @ 2-5 leaf stage of weeds fb Inter cultivation (IC) @ 60 DAS. Conclusion: Application of pre-emergent followed by post emergent herbicides control the early and later flush of weeds. It avoids the emergence of broad spectrum weed flushes and weed shift. Integrated herbicidal application along with intercultural operations was found better in keeping weeds under a threshold than following a single method.

“…Clodinafop‐propargyl + sodium‐acifluorfen could lead to increased weed control and grain yield of crops such as soybean, groundnut, and blackgram in India. These studied regions represent the diversified agro‐ecologies that include the soil orders Vertisol, Alfisol, and Inceptisol (Hanumanthappa et al, 2021; Meena et al, 2022; Thimmegowda et al, 2022). Thus, clodinafop‐propargyl + sodium‐acifluorfen has the potential to enhance weed control efficacy and mungbean yields across regions.…”

“…It is rapidly metabolised by the soybean to non‐active substances and is effective for broad‐spectrum weed control (Jha et al, 2014). In legume crops, clodinafop‐propargyl + sodium‐acifluorfen as POST resulted in effective weed control and higher grain yield of groundnut ( Arachis hypogaea L.) (Hanumanthappa et al, 2021), soybean (Meena et al, 2022), and blackgram ( Vigna mungo (L.) Hepper) (Thimmegowda et al, 2022). Herbicide selectivity can be modified with alteration in dose, time of application, selection of crop, and stage (Das, 2008; Nath, Das, et al, 2018b; Susha et al, 2018).…”

Weeds result in a significant yield loss in mungbean (Vigna radiata [L.] R. Wilczek).However, post-emergence (POST) herbicides are limited in mungbean for broadspectrum weed control. Therefore, we evaluated the efficacies of different herbicides in mungbean to find a suitable broad-spectrum POST herbicide. Nine herbicides, weedfree check, and unweeded control treatments were tested in a randomised block design with three replications for two consecutive years. Among the tested herbicides, clodinafop-propargyl + sodium-acifluorfen 122.5 g a.i. ha À1 applied at 15 days after sowing (DAS) reduced the broad-leaved weed dry weight at 35 DAS and harvest by 55.8% and by 58.6% (p < 0.05) compared with the unweeded control respectively. Notably, it minimised the total weed dry weight by 23.1%-30.3% compared with the recommended herbicide pendimethalin 1 kg a.i. ha À1quizalopfop-p-ethyl 100 g a.i. ha À1 (p ≤ 0.05). Clodinafop-propargyl + sodium-acifluorfen had higher weed control index (58.2% at 35 DAS and 62.1% at harvest) over the remaining tested herbicides.Unweeded controls resulted in 51% yield loss compared with the clodinafop-propargyl + sodium-acifluorfen that did not differ from pendimethalin À quizalofop-p-ethyl for seed yield of mungbean. Decreasing order of treatment efficacy on mean grain yield across two years comprised the weed-free check, clodinafop-propargyl + sodium-acifluorfen and pendimethalin À quiza-lofop-p-ethyl, imazethapyr + imazamox, tembotrione, and topramezone. [Correction added on 10 November 2022, after first online publication: In the preceding sentence, changes have been made to the article content to improve clarity in this version.] Application of clodinafop-propargyl + sodium-acifluorfen led to the greatest increase in soil microbial biomass carbon, indicating higher levels of soil biological and rhizospheric activity. We suggest that clodinafop-propargyl + sodium acifluorfen is a suitable broad-spectrum option for weed management of mungbean.
