“…These results confirm earlier findings in which it was shown that glyphosate has higher inhibitory effect on root growth compared to shoot [Cornish 1992, Lejczak et al 1996, Petersen et al 2007, PiotrowiczCieślak et al 2010. Roundup applied to root-zone decreased fresh weight of cucumber seedlings which did not exceed 20% compared to the control plants [Sacała et al 2011]. The inhibitory effect of glyphosate occurring in the soil on growth of non-target plants was also demonstrated in sunflower seedlings [Tesfamariam et al 2009].…”

“…Also, in experiments by Wagner et al [2003] a close correlation between the response of young maize seedlings and glyphosate absorbed from the soil was found. According to Sacała et al [2011] a small amount of the glyphosate residues in root zone markedly inhibited growth of non-target cucumber seedlings and significantly changed their metabolism. Especially the herbicide considerably suppressed the growth of cucumber roots.…”

The response of radish seedlings (Raphanus sativus L. subvar. radicula Pers.), as non-target plant, to various doses of glyphosate applied to root zone was studied in the experiment. The glyphosate was used at concentrations 0.1, 0.5 and 2.0 mM, and the study was conducted on seedlings grown in hydroponic cultures in controlled light and temperature conditions. In the experiment, roots of seedlings were exposed to glyphosate for 4, 7 or 14 days. In order to evaluate the effect of glyphosate, length and biomass of the seedling organs, as well as contents of anthocyanins in hypocotyls and cotyledons have been measured. Glyphosate applied to root zone had considerably higher impact on the growth of the primary root than shoot of radish seedlings. Short-term exposure to glyphosate led to the stimulation of growth and biomass organs of the radish seedling, but such treatment had no effect on the contents of anthocyanins in the cotyledons and hypocotyl. However, after longer exposure to glyphosate a decrease of anthocyanins content in the hypocotyl and its increase in the cotyledons was noted.

“…The inactivation of glyphosate in soil has been attributed to adsorption on phosphate-binding sites and microbial degradation (Blake and Pallett 2018;Giesy et al 2000;Sprankle et al 1975). Varying results have been reported in the literature about the effect of glyphosate residue and/or its metabolites, including AMPA on nontarget species as a result of dynamic interactions in soil influenced by diverse soil-physicochemical and biological properties (Piotrowicz-Cieślak et al 2010;Sacała et al 2011;Wagner et al 2003).…”

Glyphosate is the most widely used herbicide in the United States; however, concern about increasing residues of glyphosate and its metabolite aminomethylphosphonic acid (AMPA) in soil is escalating. There is a lack of scientific literature examining the response of cover crops to soil residues of glyphosate or AMPA. The objectives of this study were to evaluate the impact of glyphosate or AMPA residues in silty clay loam soil on emergence, growth, and biomass of cover crops, including cereal rye, crimson clover, field pea, hairy vetch, and winter wheat, as well as their germination in a 0.07% (0.7 g/L) solution of AMPA or glyphosate. Greenhouse studies were conducted at the University of Nebraska-Lincoln to determine the dose response of broadleaf and grass cover crops to soil-applied glyphosate or AMPA. The results indicated that soil treated with glyphosate or AMPA up to 105 mg ae kg–1 of soil had no effect on the emergence, growth, above-ground biomass, and root biomass of any of the cover crop species tested. To evaluate the impact of AMPA or glyphosate on the seed germination of cover crop species, seeds were soaked in petri plates filled with a 0.7 g L−1 solution of AMPA or glyphosate. There was no effect of AMPA on seed germination of any of the cover crop species tested. Seed germination of crimson clover and field pea in a 0.7 g L−1 solution of glyphosate was comparable to the nontreated control; however, the germination of cereal rye, hairy vetch, and winter wheat was reduced by 48%, 75%, and 66%, respectively, compared to the nontreated control. The results suggested that glyphosate or AMPA up to 105 mg ae kg–1 in silt clay loam soil is unlikely to cause any negative effect on the evaluated cover crop species.
