“…These results were corroborated with the findings of Ramadevi et al (2021). Complete death was observed in ragi plants that were treated with POE application of topramezone 20 g ha -1 which might be due to 4-Hydroxy phenyl-pyruvate dioxygenase (HPPD) enzyme inhibition in finger millet (Ramadevi et al, 2021). Lower growth of the plant parameters was observed with the POE application of tembotrione 12 g ha -1 (64.35 cm plant height, 66 number of total tillers and 3637 kg ha -1 DMP at harvest).…”

“…The increased growth parameters were the consequence of effective weed control, which reduced competition for finger millet and enhanced nutrient availability, which increased the number of tillers and plant height, which in turn increased the dry matter production in finger millet crop. These results were corroborated with the findings of Ramadevi et al (2021). Complete death was observed in ragi plants that were treated with POE application of topramezone 20 g ha -1 which might be due to 4-Hydroxy phenyl-pyruvate dioxygenase (HPPD) enzyme inhibition in finger millet (Ramadevi et al, 2021).…”

“…The Leeser weed density and weed dry weight at 90 DAT by the application of pyrazosulfuron ethyl 15 g ha -1 was due to the inhibition of ALS enzyme activity in the meristematic tissues of weed species that ultimately lead to the poor growth of weeds. These findings are in line with Ramadevi et al (2021) in finger millet, Ramesha et al (2017), Pal et al (2012), Saini et al (2008), Angiras and Kumar (2005) and Chopra and Chopra (2003) in transplanted rice.…”

Background: Weeds smother the finger millet due to crop’s slow growth during the initial stages which reduces the yield substantially by 5-70%. Intensive use of herbicides is gaining popularity among the farmers now a days due to its effectiveness in controlling weeds, timeliness and reduced cost. Methods: The current field experiment was conducted at Tamil Nadu Agricultural university during kharif season, 2021 under irrigated condition with twelve herbicide treatments laid out in Randomized Complete Block Design (RCBD) with three replications. Result: Pre-emergence application of pyrazosulfuron ethyl 15 g ha-1 significantly reduced the total weed density and total weed dry weight at 90 days after transplanting over all the other herbicides used. This treatment also considerably improved the plant parameters such as plant height, total number of tillers, plant dry matter production, Grain and stover yield and yield parameters such as productive tillers, ear head weight of transplanted finger millet which was statistically followed by the application of pendimethalin 750 g ha-1 as pre-emergent spray. Similar trend was followed in case of net returns and B: C ratio. while lower plant parameters were observed with the application of tembotrione 12 g ha-1.

“…Sukanya et al [95] revealed that pre-emergent application of Butachlor 50 EC 750 g a.i./ha within three days after sowing has recorded significantly higher weed control efficiency in Kodo millet. Application of Oxyfluorfen@ 0.1 kg/ha as Pre emergence at three days after planting Propanil @ 2.24 kg/ha as Post emergence, Pyrazosulfuron-ethyl @ 15 g/ha as Pre emergence at 2 days after planting and Penoxsulam @ 20 g/ha as Post emergence at 20 days after planting are effective to control broad range weeds in finger millet in India (Bhargavi et al [96]; Ramadevi et al [16]).…”

“…Depletion of soil-water by weeds, however, may create severe moisture stress conditions for the millets to grow. 5-73 percent reduction in grain yield of Finger millet (Kujur et al [12], Shubhashree and Sowmyalatha [13], Asargew and Shibabawu [14], Dubey and Mishra [15], Ramadevi et al [16]), 55-67.3 percent reduction in Kodo millet (Lekhana et al [17], Prajapathi et al [18], Jawahar et al [19], Vinothini and Arthanari [20], ICAR-DWR [21]), 30-63.5 percent reduction in grain yield of Barnyard millet (Kumar et al [22], Shamina et al [23], ICAR-DWR [21]) and 59.6 percent yield reduction in little millet (ICAR-DWR [21]) were reported. Manual weeding is the most commonly adopted for weed control in millet.…”

Presently, agriculture is facing tremendous problem due to climate change and global warming. To ensure food and nutritional security at national level, there is an immediate need to promote the cultivation of millets as millets are considered climate smart and nature friendly crops because of high nutritive value and can withstand under warm and drought conditions with short life, low external inputs requirement, tolerance to water and temperatures stress. Ten millet crops have been declared as ‘Nutri Cereals’ which include three major millets i.e., pearl millet, sorghum and finger millet; five minor millets i.e. foxtail millet, proso millet, kodo millet, barnyard millet, little millet; and two pseudo millets i.e. kuttu (buckwheat) and amaranthus. Due to sluggish growth in initial phases of life, millets proved relatively poor competitors against weeds. Manual weeding is the most commonly adopted for weed control in millets. But the non-availability of labour and ever-increasing labour wages have compelled the farmers to seek alternate method of weed management. Herbicide use is the most viable method of weed control but their continuous and excessive use is not advisable due to its ill effects on environment and development of herbicide resistance in weeds. Very limited options are available in literature for weed control in minor millets. Thus, integrated weed management practices should be followed on site and time specific basis for effective and efficient weed management in minor millets. For integrated weed management in minor millets, 2-3 times inter-cultivation and 1-2 time hand weeding during initial 25 days after sowing in addition to pre-emergence spray with Isoproturon @ 0.5 -1.0 kg a.i./ha and post emergence spray of 2, 4-D sodium salt @ 0.75-1.0 kg a.i./ha at 20-25 days after sowing should be done for effective weed control.

Soybean (Glycine max L.) is a vital leguminous crop known for its rich nutritional profile, includ-ing high protein and oil content, making it a valuable resource in global agriculture and human nutrition. In Pakistan due to regulatory issues non-GMO soybean is grown therefore, the universal herbicide control method is not applicable. Similarly, for other crops, specific herbicides are avail-able but for soybean no crop specific herbicide is present. A comprehensive study was conducted over two growing seasons, in 2022 and 2023, at Agronomic Research Farm University of Agri-culture Faisalabad. The research involved 16 different treatments, including both six pre-emergence and eight post-emergence herbicides as well as a control group and weedy check. Findings of this study showed that critical importance of weed management in soybean cultiva-tion, as unchecked weed infestation can lead to substantial yield losses. Among the pre-emergence herbicide S-Metolachlor + Pendimethalin performed best and showed higher plant height (54.33 cm & 53.67 cm), 100 grain weight (11.57 g & 12 g), seed yield plant-1 (13.07 g and 12.87 g), lower Susceptibility Index (10%), higher weed control percentage (91.21% & 95.65%) higher weed con-trol efficiency (92.02% & 93.43%), herbicide efficiency index (27.54% & 32.48%) and lower weed index (18.16% & 21.70%) during 2022 and 2023 respectively. However, in post emergence herbi-cide the Fluizefop-p-butyl is most effective herbicide due to less crop injury 10% Susceptibility In-dex, higher plant height (42.67 cm & 44 cm), whole plant weight (93.33 g & 95 g), 100-grain weight (11.40 g & 11.77 g), seed yield plant-1 (12.87 g & 13.13 g), higher weed control percentage (91.12% & 91.03%) higher weed control efficiency (89.73% & 92.36%, herbicide efficiency index (21.18% & 30.41%) and lower weed index (19.42% & 20.08%) in both 2022 and 2023 respectively. Notably, herbicides such as S-Metolachlor + Atrazine + Mesotrione, Topramezone, Mesosulfu-ron-methyl + Iodosulfuron-methyl sodium and Mesotrione + Atrazine led to complete plant mor-tality, resulting lethal to soybean. The findings of this study support the hypothesis that screened the best suitable herbicides with less plant injury, and higher efficiency index. So, it is recom-mended that the application of S-Metolachlor + Pendimethalin as PRE and Fluizefop-p-butyl as POST showed the least injury and best weed control results with higher grain yield.
