“…The herbicide pendimethalin promoted control of 26 and 40% at seven and 21 DAT, respectively; but at 35 DAT no control of ryegrass plants was observed. The use of pendimethalin has already been described as having a L. multiflorum control greater than 90% with similar doses (500 and 1,000 g•ha -1 ) (Alshallash 2014) to those used in the present study. However, the authors carried out experiments in pots and under controlled conditions of temperature and humidity, with an application of pendimethalin six days after sowing and evaluation performed at 14 DAT.…”

Ryegrass and turnip are weeds that cause high yield losses when infesting barley, thus requiring adequate management. In this context, the aim of this study was to evaluate the selectivity of different herbicide treatments and weed control in the barley crop, cultivar BRS Cauê. Two field experiments were conducted in randomized blocks, with four replications. The treatments used were: pendimethalin (800 g•ha -1 ), sulfentrazone + diuron (175 + 350 g•ha -1 ), and imazaquim (150 g•ha -1 of a. e.) applied pre-emergence; and iodosulfuron (3.5 g•ha -1 ), pyroxsulam (18 g•ha -1 ), metsulfuron-methyl (3.96 g•ha -1 ), 2,4-D (670 g•ha -1 of a. e.), clodinafop-propargyl (48 g•ha -1 ), bentazon + imazamox (600 + 28 g•ha -1 ), saflufenacil (49 g•ha -1 ), bentazon (720 g•ha -1 ), carfentrazone-ethyl (120 g•ha -1 ), and imazamox (42 g•ha -1 ) applied post-emergence, with two controls (one weeded and the other infested). The use of the herbicide imazaquim caused high levels of phytotoxicity in barley. Gas exchange was less responsive to herbicide applications in relation to barley phytotoxicity and productivity.Clodinafop-propargil showed the best control of ryegrass, while the herbicides iodosulfuron, pyroxsulam, metsulfurom-methyl, 2,4-D, bentazon + imazamox, saflufenacil, bentazon, carfentrazone-ethyl, and imazaquim showed high efficiency in the control of turnip species. Imazaquim caused reduction of up to 74.7% in barley grain yield. On the other hand, iodosulufuron and piroxsulam allowed the highest grain yields of the barley cultivar, BRS Cauê, by promoting partial control of ryegrass and total control of turnip species, followed by clodinafop-propargyl and metsulfuron-methyl, which controlled ryegrass and turnip, respectively, allowing an increase in yield grain in relation to the infested control.

“…The most popular and commonly used herbicides are not free of various flaws. Alshallash [22] reported that the length of oat, sorghum, and sugar beet roots was reduced after the treatment with pendimethalin. Moreover, the herbicide was also phytotoxic to soybeans.…”

“…Moreover, the herbicide was also phytotoxic to soybeans. When pendimethalin and trifluralin were used to control ryegrass ( Lolium multiflorum ) associated with barley ( Hordeum vulgare ) [22], a strong phytotoxicological effect on barley was observed. Both herbicides controlled well growth of Lolium multiflorum and the effect of pendimethalin on barley was very negative.…”

Effect of New Thiophene-Derived Aminophosphonic Derivatives on Growth of Terrestrial Plants. Part 2. Their Ecotoxicological Impact and Phytotoxicity Test Toward Herbicidal Application in Agriculture

et al. 2018

Background: The aim of this work was to evaluate phytotoxicity of the thiophene derivatives against three persistent weeds of a high degree of resistance (Galinsoga parviflora Cav., Rumex acetosa L., and Chenopodium album) as well as their ecotoxicological impact on Heterocypris incongruens. In addition, Aliivibrio fischeri was measured. Two of eight described aminophosphonates, namely dimethyl N-(2-methoxyphenyl)amino(2-thienyl)methylphosphonate (2d) and dimethyl N-(tert-butyl)- (2-thienyl)methylphosphonate (2h), have never been reported before. Methods: The phytotoxicity of tested aminophosphonates toward their potential application as soil-applied herbicides was evaluated according to the OECD 208 Guideline. Ecotoxicological properties of investigated compounds were made using the OSTRACODTOXKITTM and Microtox® tests. Results: Obtained results showed that four aminophosphonates have interesting herbicidal properties and N-(2-methylphenyl)amino- (2-thienyl)methylphosphonate (2a) was found to kill efficiently the most resistant plant Chenopodium album. None of the tested compounds showed important toxicity against Aliivibrio fischeri. However, their toxic impact on Heterocypris incongruens was significantly elevated. Conclusions: The aminophosphonate 2a showed herbicidal potential and it is not toxic against tested bacteria (EC50 over 1000 mg/L). It was found to be moderately toxic against ostracods [mortality 48% at 10 mg/kg of soil dry weight (s.d.w.)] and this problem should be solved by the use of the controlled release from a polymeric carrier.

“…4 According to a recent report, about 14 million pounds of trifluralin was applied only in the USA in 2001. 10 Typically, trifluralin is administered to the soil to effectively manage various annual grasses and broadleaf weed species. 11 Its mechanism of action involves disrupting mitosis, which ultimately hinders root development and allows it to control weeds during their germination stage.…”
