“…Dharam et al (2018) reported that post emergence application of tembotrione 120 g ha -1 along with surfactant (1000 ml ha -1 ) at 2-4 leaf stage of maize resulted in higher B:C ratio as compared to other herbicidal treatments either applied as pre or post emergence. Pre emergence application of atrazine 1.0 kg ha -1 fb tembotrione + atrazine (120 g ha -1 + 0.5 kg ha -1 ) as post emergence recorded highest net returns and B:C ratio when compared to other combinations of pre and post emergence herbicides (Mitra et al, 2018). The highest net returns and B:C ratio in maize was recorded with pre emergence application of atrazine 1000 g ha -1 fb post emergence application of tembotrione 120 g ha -1 which was followed by hand weeding twice at 20 and 40 DAS (Prithwiraj et al, 2018).…”

“…Pre emergence application of atrazine 1.0 kg ha -1 at 3 DAS fb post emergence application of 2,4-D 0.75 kg ha -1 at 21 DAS recorded higher cob length, cob diameter, number of grains cob -1 and grain yield of maize (Kandasamy, 2018). Among the different weed management practices, atrazine as pre emergence 1.0 kg ha -1 fb tembotrione 120 g ha -1 + atrazine 500 g ha -1 as post emergence application recorded significantly higher grain yield of maize which was followed by atrazine 1.0 kg ha -1 pre emergence fb tembotrione as post emergence 120 g ha -1 (Mitra et al, 2018). Nazreen et al (2018) reported that pre emergence application of alachlor 1000 g ha -1 fb post emergence application of halosulfuron methyl 67.5 g ha -1 + tembotrione 100 g ha -1 recorded higher plant height, leaf area index and dry matter production in maize at 20 and 40 DAS.…”

“…Sequential application of atrazine 1.0 kg ha -1 (PE) fb 2, 4-D 0.5 kg ha -1 at 30 DAS recorded the lowest weed density and dry biomass of weeds in corn when compared to PoE application of tembotrione 100 or 125 g ha -1 (Gaurav et al, 2018). Mitra et al (2018) revealed that in maize application of atrazine 1.0 kg ha -1 (PE) fb tembotrione + atrazine (120 g ha -1 + 0.5 kg ha -1 ) as post emergence had resulted in significantly lower weed density and biomass, with highest weed control efficiency at 40 and 60 DAS. Post emergence application of tembotrione 125 and 150 g ha -1 with surfactant at 20 DAS significantly reduced the density and dry weight of weeds in maize which was followed by tembotrione 125 or 150 g ha -1 at 30 DAS (Rana et al, 2018).…”

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.

“…The most popular/well-known herbicides which have been found to be effective when applied as a post-emergence for effectively control of weeds in CA-based maize system are Atrazine, Tembotrione (Laudis), Halosulfuron methyl (Sempra), Tembotrione (Laudis) + Atrazine, Halosulfuron methyl (Sempra) + Atrazine [58]. Earlier findings [62] revealed that pre-emergence herbicides pendimethalin and atrazine reduced the grassy and broadleaves weed population to a significant extent and among the pre-emergence herbicides, later (atrazine) resulted in a higher reduction in grass weed population at the early stage (20 days after seeding) than former (pendimethalin). But further he suggested, the post-emergence herbicides, the mixture of tembotrione + atrazine was more effective in controlling all classes of weed flora at 40 and 60 DAS.…”

Maize - Production and Use

View full text Add to dashboard Cite

Maize is a widely grown cereal after rice and wheat and contributes almost 5% to the global dietary supply. In the Eastern Gangetic Plains (EGP) including India, Bangladesh, and Nepal, maize is an emerging cash crop, because of its high yield potentiality and also the favorable climatic conditions which allow maize production round the year. In Bangladesh, area and production of maize are escalating due to the increasing demand for poultry, livestock, and fish feed, and fodder for animals and starch industries in the region. Presently, more than 90% of maize is planted by manual dibbling following 5-6 intensive tillage, which increases the cost of cultivation. The conservation agricultural (CA)-based new agricultural practices could overcome those above challenges. CA is cost-effective and environmentally friendly; however, weeds are one of the key challenges in the system. The chapter described the uses of herbicides in different ways of combinations to make effective weed control in CA-based maize to achieve potential production and profits by reducing the intensive pressure of manual weeding. The efficient and right use of pre-plant/sowing, pre-and post-emergence herbicides and their combination may be the best way for effective control of weeds in maize production.

Effects of Herbicides on the Microbial Community and Urease Activity in the Rhizosphere Soil of Maize at Maturity Stage

Studying the effects of herbicides on microbial community and urease activity in the rhizosphere soil of maize is helpful to clarify the mechanisms herbicides used to affect soil microbial environment. In this research, four common preemergence maize specific herbicides, nicosulfuron+atrazine (A1), alachlor+acetochlor+atrazine (A2), propisochlor+atrazine (A3), and acetochlor+atrazine (A4), were selected to use in a pot trial. A preemergence herbicide nonspecific for maize, dinitraniline (A0), was used as the positive control, whereas water instead of herbicide was considered as the negative control (CK). At the maturity stage, the microbial communities and urease activity in the 0-20 cm, 20-40 cm, and 40-60 cm rhizosphere soils of maize were analyzed. Results showed that A0 dramatically suppressed maize growth, with no grain got finally, while A1 displayed the weakest effect. The tested herbicides affected the microbial community in the 0-20 cm layer greater than in the 20-60 cm ones, with A1 displaying the greatest effect. In the 0-20 cm soil, A1 largely reduced the relative abundance of the top three dominant genera, Prevotella, Barnesiella, and Lactobacillus in the CK soil, by 99.0%, 98.7%, and 79.2%, and made Pseudomonas, Gemmatimonas, and Sphingomonas became the new dominant genera, while A2 and A3 displayed similar but slighter effects. All herbicides dramatically reduced the relative abundance of the top one dominant fungal phylum (Ascomycota) and genus (Diatrype) in the CK soil, from 45% to 5.2%-7.9% and 42% to 2.1%-3.2%. A0 dramatically dropped the urease activity in the 0-60 cm soils, by 30.5%-33.1%, whereas A1-A4 displayed an unsignificant effect. In conclusion, A1 is a suitable herbicide for maize. Both the bacterial community and urease activity in the 0-20 cm rhizosphere soil are suitable indices to evaluate the effects of preemergence herbicides on maize growth and soil microbial environment.
