“…The activity and selectivity of herbicides are affected by various factors, such as temperature, moisture, soil texture, weed biology, physiological, and biochemical processes [1][2][3], and thus, the amount of herbicides reaching weeds is actually a small percentage of the pesticides applied [4,5]. It is, therefore, logical to enhance the application of pesticides to deliver more potent ingredients directly to the targeted weeds, thereby enabling the application of the smallest possible dose of herbicide.…”

In the period 2017–2019, field experiments were conducted at the Research and Education Center Gorzyń, unit Złotniki (52°486′ N; 16°819′ E), Poznan University of Life Sciences, at the Luvisols, under natural weather conditions, to evaluate the effect of multifunctional methylated seed oil (EXP 1, 2, and 3) and standard adjuvants (AtB and S) on the efficacy of mixtures phenmedipham + ethofumesate and metamitron applied in full (PEM 1) and reduced rates (PEM 2) in sugar beet. Field studies were carried out and three applications of herbicides were administrated subsequent to the emergence of weeds (BBCH 11–12). PEM applied at reduced rates with EXP was more effective than after AtB and S adjuvants. They enabled the attainment of high and consistent efficacy of herbicides (with EXP—96–97%, AtB—97%, S—95%, compared to PEM 1—93%, and PEM 2—82%), irrespective of varying weather conditions during, and subsequent to, their application. The sugar beet root yield from herbicide treatments after tested adjuvants was higher than from the untreated control and after application of reduced rates of herbicides without adjuvants.

“…High concentrations of CO 2 reduce stomatal conductance, which can alter the efficacy of foliar herbicides [6]. Some studies have indicated that the efficacy of glyphosate in controlling Paspalum dilatatum, Conyza canadensis, and Chenopodium album could be reduced at high CO 2 concentrations [7][8][9]. When herbicides are sprayed on weed leaves at high temperatures, leaf cuticles become more fluid and more readily penetrated by fat-soluble compounds, thus demonstrating low selectivity [10].…”

Weed Response to ALS-Inhibitor Herbicide (Sulfosulfuron + Metsulfuron Methyl) under Increased Temperature and Carbon Dioxide

et al. 2023

Information on the impact of climate change on the growth of weed species and their sensitivity to herbicides could help to establish an efficient weed management strategy. Due to the excessive use of acetolactate synthase (ALS)-inhibitor herbicides, resistance to those herbicides is increasing globally. It is, thus, crucial to find out whether the efficacy of these herbicides will change in the future due to the increase in temperatures and carbon dioxide concentration. Therefore, this work aimed to evaluate the impact of temperature and carbon dioxide (CO2) changes on the growth of Amaranthus retroflexus, Bromus tectorum, Chenopodium album, and Echinochloa crus-galli, including the assessment of sulfosulfuron 75% + metsulfuron methyl 5% efficacy in these weeds. A factorial experiment was performed in a completely randomized design with a factorial arrangement (2 × 2 × 6), including two CO2 concentrations (400 and 700 ppm), two temperature regimes (30/20 °C and 34/24 °C day/night), and six herbicide rates (0, 25, 37.5, 50, 62.5, and 75 g ha−1). As a result, it was seen that temperature and CO2 concentration changes influenced the morphological variables of the weeds. The temperature regime affected the herbicide’s effectiveness on B. tectorum and E. crus-galli. The herbicide’s efficacy on weed species was affected by the interaction of herbicide rates and the temperature regime, except for on E. crus-galli; the highest efficacy was observed at 30/20 °C and at a rate 50% higher (75 g ha−1) than the recommended one (50 g ha−1). Except for E. crus-galli, increasing CO2 concentrations enhanced the herbicide efficacy and ALS enzyme activity inhibition in all the weed species, but had the greatest effect on C3 weeds. We found that temperature and CO2 levels can alter the efficacy of weed control with herbicides, with clear differences between C3 and C4 plants. As a result, by increasing the temperature and concentration of CO2, breeders and farmers may achieve the desired control of weed species such as B. tectorum, C. album and A. retroflexus by applying lower doses of this herbicide.

“…Climate change can affect weed biology, weed dynamics, phenology, and management by affecting various physiological and biochemical processes. Weed plants react to the changing climate, which has serious consequences for weed management, especially using herbicides [28,29].…”

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.
