“…The significantly highest crude protein, crude fiber, and moisture recorded at 5 WAS time of application might be due to the effective weed control observed at that stage. The timely application of herbicides to control weeds in maize fields significantly improved the quality of maize (Karkanis et al 2020).…”

Abstract. Tizhe TD, Alonge SO, Iortsuun DN, Adekpe DI, Batta K. 2022. Evaluation of effect of nicosulfuron at different time of application on the chemical component of maize (Zea mays). Nusantara Bioscience 14: 123-128. This study was aimed at evaluating the effect of nicosulfuron at different concentration and time of application on the chemical compositions of maize (Zea mays L.) grain. A field experiment was conducted during the 2019 and 2020 cropping season. Using a split plot design, maize seed was planted; and four different concentrations of nicosulfuron (50, 100, 150 and 200 g/ha) were applied at 3, 5 and 7 weeks after sowing (WAS). The maize grain obtained were analyzed of its proximate, amino acids and mineral contents using a standard procedures. The results showed that both the different concentrations of nicosulfuron and its time of application had significant effect on the proximate compositions except on the ash content. The 5 WAS application time had the significantly highest content of protein, crude fibre and moisture with 11.35, 2.60 and 12.01% respectively; and lowest of carbohydrate (70.58%) and crude fat (2.33%). The nicosulfuron was also observed to have a significant effect on all the amino acids and mineral (except on N) contents of the maize grain with 100 g/ha recording the significantly highest content of almost all the amino acids; and 50 g/ha the lowest. The 5 WAS had the highest of virtually all the amino acids; while 3 WAS the lowest. Therefore, nicosulfuron and time of application both have a significant effect on the proximate, amino acids and Mg and Ca components of maize grain; which means that the use of nicosulfuron at concentrations especially above 100 g/ha and at time other than 5 WAS negatively affect the chemical components of maize grain.

“…During the most critical period of maize competition, yield loss by weeds, in some cases, can exceed 30%, depending on climatic conditions and management techniques [13,14]. Maize crops should be maintained without weeds for the first 6 to 8 weeks after sowing to maximize yield [15] and are often characterized by complexes of weed flora, broad-leaf weeds, and grass weeds [16]. According to Lehoczky et al [17], weed competition reduced maize biomass by 64% in weedy plots.…”

The aim of this study was to investigate specific management methods for controlling weeds under different climate conditions by reducing the risk of herbicide resistance in maize. Herbicide trials were placed at two locations during 2017 and 2018 and organized in a randomized block design with four replicates of all herbicide combinations (terbuthylazine—pre-emergence and mesotrione post-emergence treatment, terbuthylazine + mesotrione in post-emergence treatment, and terbuthylazine—pre-emergence and dicamba in post-emergence treatment). In the trials, 13 specific weeds were observed. High effectiveness was achieved when using commercial preparations with two active ingredients (terbuthylazine and mesotrione) in both years of research. As the year 2018 featured a higher amount of precipitation, uneven weed sprouting occurred, which resulted in a large number of Setaria glauca (18.50 No m−2), Solanum nigrum (16.50 No m−2), Datura stramonium (13.75 No m−2), and Chenopodium hybridum (10.50 No m−2) plants. Herbicide phytotoxicity was not expressed in maize. Ambrosia artemisiifolia, Solanum nigrum, and Datura stramonium had the highest competitive index (CI 10). The highest maize yield was observed under the application of terbuthylazine + mesotrione in post-emergence (14.223 t/ha). This combination led to the highest weed control costs (35.60 EUR/ha) in 2018, while in 2017, the yield was 12.829 t/ha, with a control cost of 33.99 EUR/ha.

“…More specifically, a single johnsongrass plant can produce up to 90 m of rhizomes and 80,000 seeds in one growing season (Riar et al 2011;Ryder et al 2018), making its control very difficult (Panozzo et al 2017). Plants from rhizomes exhibit higher growth rates and are more competitive than plants originating from seeds (Acciaresi and Guiamet 2010;Karkanis et al 2020;Mitskas et al 2003).…”

Target-site cross-resistance to ALS inhibitors in johnsongrass originating from Greek cornfields

Dicamba is a synthetic auxin herbicide that may be applied over the top of transgenic dicamba-tolerant crops. The increasing prevalence of herbicide-resistant weeds has resulted in increased reliance on dicamba-based herbicides in soybean production systems. Because of the high volatility of dicamba, it is prone to off-target movement, and therefore has been of increased concern regarding dicamba drift onto nearby specialty crops. The present study evaluates twelve mid-Atlantic vegetable crops species for sensitivity to sub-lethal rates of dicamba. Soybean, snap bean, lima bean, tomato, eggplant, bell pepper, cucumber, summer squash, watermelon, pumpkin, sweet basil, lettuce, and kale were grown in the greenhouse and exposed to dicamba at 0, 0.056, 0.11, 0.28, 0.56, 1.12, 2.24 g ae ha−1, which is respectively 0, 1/10,000, 1/5,000, 1/2,000, 1/1,000, 1/500, and 1/250 of the maximum recommended label rate for soybean application (560 g ae ha−1). Vegetable crop injury was evaluated 4 weeks after treatment using visual rating methods and leaf deformation index (LDI) measurements. Overall, snap bean was the most sensitive crop species with dicamba rates as low as 0.11 g ae ha−1 resulting in significantly higher leaf deformation levels compared to the nontreated control. Other Fabaceae and Solanaceae species also demonstrated high sensitivity to sub-lethal rates of dicamba with rates ranging 0.28 to 0.56 g ae ha−1 causing higher leaf deformation compared to the nontreated control. While cucumber, pumpkin, and summer squash were no or moderately sensitive to dicamba, watermelon showed greater sensitivity with unique symptoms at rates as low as 0.056 g ae ha−1 based on visual evaluation. Within the range of tested dicamba rates, sweet basil, lettuce and kale demonstrated tolerance to dicamba with no injury observed at the maximum rate of 2.24 g ae ha−1.
