Glyphosate-based herbicides (GBHs) are the most frequently used herbicides
globally. They were launched as a safe solution for weed control, but
recently, an increasing number of studies have shown the existence of GBH
residues and highlighted the associated risks they pose throughout
ecosystems. Conventional agricultural practices often include the use of
GBHs, and the use of glyphosate-resistant genetically modified crops is
largely based on the application of glyphosate, which increases the
likelihood of its residues ending up in animal feed. These residues
persist throughout the digestive process of production animals and
accumulate in their excretion products. The poultry industry, in
particular, is rapidly growing, and excreted products are used as plant
fertilizers in line with circular food economy practices. We studied the
potential effects of unintentional glyphosate contamination on an
agronomically important forage grass, meadow fescue (Festuca pratensis)
and a horticulturally important strawberry (Fragaria x vescana) using
glyphosate residues containing poultry manure as a plant fertilizer in a
common garden experiment. Glyphosate in the manure decreased plant growth
in both species and vegetative reproduction in F. x vescana. Furthermore,
our results indicate that glyphosate residues in organic fertilizers might
have indirect effects on sexual reproduction in F. pratensis and herbivory
in F. x vescana because they positively correlate with plant size. Our
results highlight that glyphosate can be unintentionally spread via
organic fertilizer, counteracting its ability to promote plant growth.
Dataset on the effects of glyphosate residues in bedding used as
fertilizer on the growth, reproduction and herbivory of Festuca pratensis
and Fragaria x vescana. (1) Growth of F. pratensis was estimated as the
biomass of the oven dried, aboveground parts of the plants at the end of
the growing season. (2) The number of F. pratensis inflorescences
was counted as a measure of reproduction. (3) Growth of the F. x vescana
was estimated as plant size index calculated as the diameter × height of
the rosette at the end of the growing season. (4) F. x
vescana (vegetative) reproduction was measured as runner biomass. (5) As
an estimate of herbivory, the presence of aphids was recorded both for F.
pratensis and F. x vescana. In addition, the number of chewing
insect-damaged F. x vescana leaves (as indications of hymenoptera,
lepidoptera, and/or coleoptera damage) was calculated.
