“…Adjuvant mixed with herbicide efficiently can minimize the amount of sprayed herbicide while significantly lowering total weed control expenses. The addition of adjuvant improved the efficiency of herbicides and resulted in a 98% reduction of weed biomass, while 87% of biomass was reduced by applying herbicide alone [38,[44][45][46].…”

A field trial was conducted to evaluate the interactive effect of seed rates and herbicides in combination with adjuvants on weed dynamics and wheat yield. This study was comprised of 3 seed rates; 100 kg h -1 (S1), 130 kg h -1 (S2), 160 kg h -1 (S3), and 3 herbicide dosages (100% recommended dose of Mesosulfuron-methyl + Iodosulfuron-methyl-sodium (H1), 75% of the dose (H2), and 75% dose + adjuvant (H3). The results revealed that average weed density, fresh weight, and dry weight were lower in seed rate 160 kg h -1 by 33.37%, 31.52%, and 28.78% compared to 100 kg h -1 before herbicide application, respectively. After 30 days of herbicide application, weed density, fresh weight, and dry weight were 42.16%, 34.74%, and 40.91% less in treatment with the combination of S3H3 compared with S1H2. Yield and yield parameters were significantly affected by the different seed rates and herbicide dosages. 1000-grain weight, spikelets, and grains/spike were greater in the lower seed rate (100 kg h -1 ) with H3, while the grain yield, biological yield, and harvest index were 26.05%, 21.81%, and 5.39% higher in the treatment S3H3 as compared with S1H2. To achieve optimal grain yield, a seed rate of 160 kg h -1 is recommended, along with 75% of the recommended herbicide dose with adjuvant.

“…The adoption of dicamba-tolerant crops in the USA, together with glyphosate-tolerant crops, influenced research, and most of recently available papers discuss those two herbicides, either for efficacy or offtarget movement. However, no previous research tested the herbicide mixture of mesotrione and rimsulfuron plus thifensulfuron-methyl on selected crops, while those herbicides can be used as alternatives for controlling glyphosate-resistant weeds (Brankov et al 2023). Using alternative herbicides to glyphosate and dicamba is needed for successful weed control (Costa et al 2019), while the literature reported no results on the drift of those herbicide mixtures to nearby crops.…”

Awareness regarding pesticide off-target movement exists all the time, and in the last few years, research on herbicide drift has been investigated more than ever. The implications with auxin herbicides include very high susceptibility to non-GM crops, tank contamination or volatility issues (McCown et al. 2018;Alves et al. 2020;Soltani et al. 2020). Due to this fact, all applications regarding these kinds of herbicides are regulated with strict application guidelines, including restrictions on nozzle type, and applications are labelled requiring the use of extremely coarse or ultra-coarse sprays

“…This is to be expected, as coarse droplets are less susceptible to air currents. Thus, if efficacy is not reduced, nozzles that form larger droplets should be used in applications (Brankov et al, 2023).…”

This study aimed to evaluate the quality of application using both RPA and ground techniques in corn cultivation using different spray nozzles in Brazilian savannah (Cerrado). The experiment was conducted using a completely randomized design, with four treatments and eight repetitions. The treatments involved two methods of application: aerial (RPA, 10 L ha-1) and ground (backpack sprayer, 100 L ha-1); and two types of nozzles: the standard flat fan nozzle XR 11001 and the air induction flat fan nozzle AirMix 11001. To study the quality of the application, the deposition was evaluated using a tracer and spectrophotometry, and the droplet spectrum, evaluated through the analysis of water-sensitive paper. Furthermore, a study on application quality was conducted using the Statistical Process Control methodology. The results demonstrated that with RPA, the deposition was higher, and the AirMix 11001 nozzle also stood out in this variable. No non-random behavior was observed in the deposition. Ground application showed the best performance in terms of target coverage and droplet density. The XR 11001 nozzle resulted in a higher droplet density. Overall, the XR11001 nozzle and the RPA application showed smaller volume median diameters (VMDs), indicating a higher potential for drift, which should be taken into account. Given the results obtained, it can be stated that the use of RPAs for agricultural spraying is viable for application.
