“…Weather conditions influence the growth and development of maize plants. The development of weeds is also strongly impacted by the course of the post-weather, but they are much better adapted to cope with unfavorable conditions [22]. For optimal growth and development of maize plants, different temperatures are required depending on its development stage and the time of day.…”

Weed control in maize is usually limited to a single herbicide treatment, but the application of two or more herbicides is associated with many benefits, e.g., increasing the spectrum of control weeds, reducing the risk of damage to crops by using reduced rates of herbicides, limiting their residues in the soil or crop, etc. This field experiment was conducted in the years 2016–2018 to determine whether the split application of soil-applied thiencarbazone-methyl + isoxaflutole and foliar-applied mesotrione + nicosulfuron + rimsulfuron, in reduced rates with adjuvants, can contribute to enhancing herbicide effectiveness and increasing maize yield. Weed control in maize in a split-dose system with a mixture of thiencarbazone-methyl + isoxaflutole at strongly reduced rates with the addition of UAN and the adjuvant Atpolan SoilMaxx or Grounded, and then mesotrione + nicosulfuron + rimsulfuron at strongly reduced rates with UAN and Atpolan SoilMaxx or Actirob 842 EC allowed for great control of weeds. The total amount of substances was slightly higher than in single treatments with adjuvants, but lower than for individual active substances, leading to a reduction in the amount of active substances reaching the environment, while maintaining very high herbicide efficacy.

“…Weather conditions, primarily temperature and precipitation during the growing season, have the strongest influence on maize growth and development. Weed development is also highly dependent on the weather, but weeds usually have higher plasticity (Pilipavicius 2015). Conditions that favoured growth and development of sweet corn plants were found only in the first year of study, which was characterized by high precipitation and moderate temperatures.…”

Weeds in sweet corn reduce the yield and are economically more harmful than other pests. The aim of this study was to evaluate the effects of mechanical weed control and efficacy of pre-and postemergence applied herbicides in sweet corn, and their influence on weed control expressed by various indices, corncob yield and net return. Field studies were carried out with preemergence thiencarbazone-methyl + isoxaflutole (at 29.7 + 74.3 g • ha -1 ), postemergence S-metolachlor + terbuthylazine (937.5 + 562.5 g • ha -1 ), mesotrione + terbuthylazine (100 + 652 g • ha -1 ), terbuthylazine + mesotrione + S-metolachlor (656.3 + + 131.3 + 1093.8 g • ha -1 ), weed free (WF, hand weeding), and mechanical weeding (MW, hoeing) to assess weed control, corncob yield and net return. Variability in potential yield losses was observed between years due to weather conditions at the level of 30 to even 93%. Hand weeding was the most effective, but it is expensive and needs is labour consuming, unlike mechanical weeding which was the cheapest but simultaneously the least effective. Among pre-and postemergence applied herbicides, a mixture of terbuthylazine + mesotrione + S-metolachlor was the most efficacious weed control treatment. It gave high corncob yield and economic net return.

“…Maize plant growth and development depend on the temperature and rainfall during vegetation season [28] similar to weed plants that also react to weather changes, but their response usually has higher plasticity [29]. Generally, weather conditions during field experiments were rather favourable for both maize and weed species plants.…”

Field trials were conducted with preemergence dimethanamid-P + pendimethalin (D + P; 850 + 1000 g·ha−1) and reduced rates (637.5 + 750 g·ha−1 and 452 + 500 g·ha−1, 75% and 50% of label rate), followed by strongly reduced rates of postemergence herbicides nicosulfuron + rimsulfuron + dicamba (N + R + D; 4 + 15.6 + 93.5 g·ha−1, 50%), tembotrione (T; 33 g·ha−1, 50%), mesotrione + nicosulfuron (M + N; 37.5 + 15 g·ha−1, 50%), foramsulfuron + iodosulfuron (F + J; 7.5 + 0.25 g·ha−1, 20%), and nikosulfuron (N; 15 g·ha−1, 33%) applied with methylated seed oil (MSO; 1.0 L·ha−1) and ammonium nitrate (AMN; 2 kg·ha−1) on 3–5 leaves of maize to assess weed control, grain yield, and economic net return. Reduced rate of soil-applied herbicide followed by reduced rates of any postemergence herbicides applied with adjuvants was the most efficacious weed control program, provided the highest grain yield of maize and similar or higher economic net return, despite 44 to 48% lower herbicide input than the program based on soil-applied herbicide mixture only. It brings not only notable economic benefits but also less negative impact on the environment.
