“…Tembotrione+atrazine as postemergence with pre-emergence pendimethalin also recorded a superior returns and benefits signifying the impact of this herbicide combination irrespective of the pre-emergence herbicides used in this experiment. Barla et al (2016) reported that preemergence atrazine or pendimethalin were equally effective in achieving higher productivity, profitability through better weed control in maize. Based on relative net profit, tembotrione alone as postemergence could also be advocated with preemergence atrazine.…”

“…Hand weeding twice removed the weeds completely and created condition which were more favourable for growth and ultimately resulted in the lowest density of later emerged weeds and their lowest dry biomass with higher weed control efficiency during the crop growth period. Manual weeding maintained its supremacy over chemical control in limiting the weed load (weed density as well as their biomass) in maize crop reported by Barla et al, 2016. Among all the herbicidal weed control treatments, alone and combined application (with atrazine) of topramezone and tembotrione was found the most effective in order to reduce the density and dry matter of weeds at all stages compared to other treatments.…”

“…Integrated weed management is the need of the day, because of its sustainability and higher productivity (Sharma et al, 2018;Kumawat et al, 2019). Weed control practices in maize resulted in 65 to 90% higher yield than unweeded (Barla et al, 2016;Kumawat et al, 2019). Topramezone and tembotrione are the new selective, post-emergence herbicides introduced for use in maize that inhibit hydroxy-phenyl pyruvate dioxygenase (4-HPPD) enzyme and the biosynthesis of plastoquinone (Swetha et al, 2015).…”

A field experiment was conducted at Research Farm of Agricultural Research Station, Ummedganj, Kota (Agriculture University, Kota), Rajasthan, India during kharif 2019 to find out the most effective herbicide combination for limiting the menace of weeds in maize. Results showed that density of monocot weeds were observed more than dicot weeds during the experimentation. The prominent weeds were Echinochloa colona, Cyperus rotundus, Digera arvensis, Amaranthus viridis, Acalypha indica and Trianthema portulacastrum etc. caused about 58.3% reduction in grain yield as over two hand weeding at 20 and 40 DAS. In general, grassy weeds were better controlled by herbicides than broad leaves weeds. Among herbicides, maximum weed control efficiency (72.18%) was achieved with application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS (72.18%) which is very close to two hand weeding at 20 and 40 DAS. Furthermore, this treatment also produced higher grain (3496 kg ha-1) and stover yield (6460 kg ha-1) which was at par with atrazine 500 g a.i. ha-1 (PE) followed by tembotrione 120.75 g a.i. ha-1 (20-25 DAS) and atrazine 500 g a.i. ha-1 (PE)+hand weeding 30 DAS with in-situ weeds mulching. Thus, pre-emergence application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS is recommended for better weed control and yield of maize.

“…Tagoura and Ibrahim (2017) while working on maize found that two hand hoeings at 15 and 30 DAS exerted the highest decrease in total number and dry weight of weeds. Hand weeding twice at 20 and 40 DAS reduced the density and dry weight of grasses, broad leaved weeds and sedges at 30 and 60 DAS of corn and recorded the highest grain yield (Barla et al, 2016). Dutta et al (2016) reported that hand weeding twice at 20 and 40 DAS produced significantly higher values of number of cobs plant -1 , grain weight cob -1 , cob length and cob girth of corn compared to the other treatments.…”

In India the highest loss (33%) is caused by weeds, followed by pathogens (26%), insects (20%), storage pests (7%), rodents (6%) and others (8%). Weeds compete with the crop for both above and below ground resources. Critical period of weed competition starts from 17 to 29 days after planting of corn, at an acceptable yield loss of 5 to 10 per cent. Herbicides are efficient tools for checking weed infestation and its usage is increasing throughout the globe due to increasing labour cost and quick weed control in various situations. The common weed management practice for Maize is pre-emergence application of selective herbicides like atrazine or pendimethalin followed by one hand weeding. Managing weeds through pre-emergence, post-emergence and sequential use of herbicides will be an ideal means for controlling the weeds in the view of economics and effectiveness in maize.
