abstract = {The effectiveness of a homologous series of biodegradable
rapeseed oil derivatives (triglyceride ethoxylates; Agnique
RSO series containing an average of 5, 10, 30 and 60 units
of ethylene oxide (EO) as adjuvants for foliage-applied,
water-soluble, systemic active ingredients was evaluated
employing glyphosate as an example. Previous experiments had
revealed that the surfactants used are not phytotoxic at
concentrations ranging from 1 to 10 g litre-1. The
experiments were performed using Phaseolus vulgaris L and
nine selected weed species, grown in a growth chamber at
25/20 (+/- 2) degrees C day/night temperature and 40/70 (+/-
$10)\%$ relative humidity. The surfactants were evaluated
for enhancement of spray retention, and foliar penetration
biological efficacy of glyphosate. Glyphosate was applied at
a concentration of 43 mM. The surfactants were added at
concentrations of 1 g litre-1. The commercial glyphosate 360
g AE litre-1 SL Roundup Ultra and unformulated glyphosate
served as references. The surfactants used improved spray
retention, foliar penetration and biological efficacy. Some
of the formulations were comparable to the performance of
Roundup Ultra in the aspects evaluated; some were even more
effective in enhancing spray liquid retention and promoting
glyphosate phytotoxicity in several plant species. In these
studies Agnique RSO 60 generally was most effective.},
