“…This might be the addition of adjuvants that improved weed control efficiency of metribuzin and provided more resources to crop plants instead of weeds. According to Rizwan et al (2018) , the application of herbicide increases the number of spike-bearing tillers (m –2 ) significantly. Our findings are further supported by Moraes et al (2021) who stated that herbicides applied with adjuvants either at full or reduced doses significantly decreased the weeds infestation than herbicides used alone and resultantly improved the spike-bearing tillers with concomitant reduction of non-spike-bearing tillers by supplying more space, light, and nutrients to crop plants.…”

Weeds cause a serious constraint to wheat productivity. Chemical weed control is considered the most effective method to control weeds; however, a suitable dose and combination of herbicide with adjuvants play a vital role in controlling weeds and producing maximum wheat production. A field study was conducted to investigate the effectiveness of various doses of metribuzin alone or in combination with adjuvants [Bio-power (alkyl ether sulfates and sodium salts) and Ad-500 (fatty alcohol ethoxylate)] on the growth and yield of wheat and its associated weeds. Metribuzin at 175, 140, and 105 g a.i ha–1, each in combination with adjuvants (Bio-power or Ad-500) at 400 ml ha–1, were sprayed. A weedy check was also included as a control treatment. The wheat crop was infested with Fumaria indica, Melilotus indica, Anagallis arvensis, and Phalaris minor, and metribuzin with or without adjuvant was sprayed at two- to four-leaf stage of the weeds. The photosynthetic activity, weed population of each weed, and biomass of each weed was significantly affected by all herbicides along with the adjuvant. However, maximum inhibition of tested weeds was observed where metribuzin at 175 g a.i ha–1 + Bio-power at 400 ml ha–1 were sprayed. Metribuzin sprayed at 175 g a.i ha–1 with or without Bio-power recorded a maximum 1,000-grain weight, biological yield, and grain yield. Conclusively, metribuzin sprayed at 175 g a.i ha–1 + Bio-power at 400 at ml ha–1 have the potential to improve wheat yield by inhibiting weed growth, and Bio-power was superior to Ad-500 in improving the efficacy of metribuzin against weeds of wheat crop.

“…(Marcinkowska et al, 2018) found that the addition of bioionic liquids as adjuvants to the spray solution significantly reduced the surface tension and contact angle of spray droplets and increased the area of sulfonylurea herbicide deposit on the leaf surface. (Rizwan et al, 2018) reported an increased efficacy of isoproturon+tribenuron for control of little seed canary grass and field bindweed by addition of minerals and vegetable oil adjuvants. One of the most frequent dicotyledonous weeds with the great economic importance is common lambsquarters (Chenopodium album L.) (Keller et al, 2014).…”

Environmental risks resulting from the increasing application of chemical herbicides have raised many concerns about human health and the safety of agro ecosystems and environment. Hence, it is very important to find practical and effective methods for reducing the use of pesticides in environment as well as the increasing the efficiency of these compounds. Addition of adjuvants to spray solutions could be considered as one of these methods. Greenhouse studies were conducted using a complete randomized design with a factorial arrangement during 2015-2016 to evaluate the impact of different adjuvants (citogate, canola oil, and castor oil) at concentrations of 0.1 and 0.2 (%v/v) with 5, 10, 20, 30 and 40 g a.i. ha -1 of tribenuron methyl herbicide to control common lambsquarters. Results showed that all applied adjuvants enhanced the efficacy of tribenuron methyl in decreasing the biomass of common lambsquarters. Efficacy of this herbicide increased with enhancing its concentrations. The required dose of herbicide to give 50 per cent common lambsquarters control (ED50) for no adjuvant, citogate, castor oil, and canola oil application (0.2 (%v/v)) was 21.24, 11.48, 11.65, and 11.81 g a.i. ha -1 , respectively. Totally the application of citogate and canola oil had the highest and the lowest impact on tribenuron methyl performance to control of common lambsquarters respectively. Also, the Relative Potency values were significantly increased when adjuvants were added to this herbicide. The results revealed that the use of citogate and vegetable oils can increase the efficiency tribenuron methyl, and reduce the application rate of this herbicide in agro ecosystems.

Nanoherbicides are articulated by exploiting the prospective of nanotechnology for effectively delivering chemical and biological herbicides using nanomaterial‐based herbicide combinations. The nanoparticles were characterized using X-ray diffraction and FT-IR. On the targeted weeds, the nanoherbicides were sprayed at the third to fourth leaf stage. Six different doses were applied. The mortality and visual injury caused by both chitosan-based nanoherbicides reached 100% at the recommended dose of standard herbicide. The 5-fold lower dose exhibited weed density and maximum wheat yield and related parameters. For the same traits, the nanoherbicide at 10-fold lower dose of commercial herbicides showed a comparable influence as the suggested dose. The size of both herbicides was found to be 35–65 nm. It was observed that the clodinofop-propargyl nanoherbicide has an intense peak appearing at a 2θ value of 29.83°, corresponding to the (176) plane of the anatase phase and NPs of fenoxaprop-P-ethyl showed an intense peak around the 2θ value of 30.55° corresponding to the (74) plane of the anatase phase. The FT-IR spectra of fenoxaprop-P-ethyl clearly showed that the major functional groups were located in the FT-IR region between 610 and 1,840 cm−1 and the major functional ones of clodinofop propargyl were located in the FT-IR region between 640 and 1,740 cm−1. Nanoherbicides could restore the efficacy of conventional herbicides by improving stability and reducing toxicity.
