Alkyl Ether Sulfate Improves Efficacy of Herbicides Against Common Goosefoot and Field Bindweed in Wheat

Abstract

-Tank mixed application of herbicides with adjuvant is required for effective weed management and to reduce herbicide load on agricultural crops. Field studies were conducted to investigate the effect of herbicides at reduced rates with adjuvant on common goosefoot (Chenopodium album) and field bindweed (Convolvulus arvensis) and grain yield of wheat for two consecutive winter seasons. Treatments included post-emergence foliar application of four herbicides viz., fluroxypyr + tribenuron-methyl + clopyralid, mesosulfuron-methyl + iodosulfuron-methyl sodium, bromoxynil + MCPA, iodosulfuron-methyl sodium (pre mixed formulations) at their recommended rates 244.5, 14.2, 444.6, 10 g a.i. ha -1 , respectively and 25% reduced rates with alkyl ether sulfate Na salt at 400 mL ha -1 as adjuvant. A weedy check was kept as control. All the herbicide treatments caused a significant reduction in densities (up to 85% and 89.2%) of C. arvensis and C. album, respectively and total dry weight (12.4-56%), N (3.7-50%), P (25-63.6%) and K (1.4-56.6%) uptakes from weedy check. Better weed control was achieved with 25% lower dose of all herbicides along with adjuvant in comparison with that recorded with their full doses without adjuvant. All herbicide treatments increased the grain yield of wheat ranging from 10.4 6-56.1% over control during both years. Herbicides with adjuvant produced significantly the higher grain yield of wheat than those observed with herbicides alone. Among all herbicide treatments, 75% doses of bromoxynil + MCPA and iodosulfuron-methyl sodium along with alkyl ether sulfate adjuvant were proved to be the best as they gave significantly the higher (4902.3 and 5159.0 kg ha -1 and 4566.5 and 4891.0 kgha -1 ) grain yields of wheat during years 2013-14 and 2014-15, respectively.

Enhancing Rice Yield and Weed Management in Direct Seeded Rice Using Ammonium Sulfate as Adjuvant with Lower Dose of Early Postemergence Herbicides

“…Further, the combined application of herbicide with adjuvants increases herbicide efficiency and retention and decreases surface tension through cuticle layer absorption (Zhang et al, 2013). Our findings of the study also line with Tanveer, Abbas, Safdar, & Ikram (2017) who concluded that 75% (MCPA + bromoxyinal + iodosulfuron-methyl sodium) with adjuvant ammonium sulfate reduced weeds density up to 25% and dry weight up to 56% of broadleaf weeds. Moreover, our data showed similarity with Donald (1985) who reported that herbicide chlorsulfuron with surfactant (0.2% v/v Tween 80) as adjuvant reduced dry mass of weeds up to 67.4% and also stop further growth of weeds.…”

“…Maximum BY, PY and HI were recorded with 75% N + AS that were statistically (P ≤ 0.05) similar with all other weeds control treatments except weedy check and 75% reduced dose of Kelion and Ryzelan. These results are close to Tanveer, Abbas, Safdar, & Ikram (2017) who concluded a 75% reduced dose of herbicides (MCPA + bromoxynil + iodosulfuronmethyl sodium) with adjuvants (alkyl ether sulfate) gave the significant results with 10.46-56.1% increase in yield of wheat over control. These results were similar to Hammami, Aliverdi, & Parsa (2014) who concluded that the application of propanil with surfactant and methylated seed oil as adjuvant gave significant results to control barnyard grass and higher yield of rice.…”

“…It also reduces the labeled dose of halosulfuron up to 25% without compromising on okra yield. Alkyl ether sulfate was reported as a responsible adjuvant as it can help in diminishing herbicide dose up to 75% of the prescribed dose without impairing its effectiveness and brought about higher grain yield (Tanveer, Abbas, Safdar, & Ikram, 2017). Javaid & Tanveer (2013) concluded that wheat grain yield was increased with herbicides along with alkyl ether sulfate sodium salt as an adjuvant when compared with the recommended dose of herbicide.…”

Improving the Management of Parthenium hysterophorus to Enhance Okra Production through the Application of Chemicals, Adjuvants and Plant Extract Blends in Pakistan

“…Important impact of adjuvant has been the recover attributes of herbicide mixture, impact on sublimation, upgrade of maintenance, alteration or improvement of spray pledges and additionally an enhanced entrance and relocation. Alkyl ether sulfate (AES) has been ended up being a decent adjuvant as it can help in reducing herbicide dose up to 75% of prescribed dose without impairing its adequacy and brought about higher grain yield (Tanveer et al, 2017). Singh et al (2004) brought about an investigation to monitor the adequacy of glyphosate only and in mixture with additives (MON 0818) to minimize the density of parthenium.…”
