classification
Option ii:
Cyperus esculentus Agriculture Evidence from NL:
Phytosanitary measures. The successful
elimination of yellow nutsedge from the entire
gladioli propagation crop had a cost of
approximately €1.5 – 3 million.
Calculations In the NL showed considerable
damage.
Losses for operators: In 1984 calculations
showed that a standard arable farm would face a
decrease in net profits from € 1000 (no
infestation) to less than €100 /ha per year. The
total loss of a flower bulb crop may easily
account to over €50.000 /ha, not counting the
loss of land value that could be estimated to be
the same.
Option iii:
Hydrocotyle
ranunculoides
(aquatic plant)
Freshwater systems (slow
flowing waters,
degradation of aquatic
ecosystem, loss of
biodiversity)
Medium to high risk. Economic impacts include
management costs of the species and flooding of
areas. Any economic benefit of the introduction
of this plant as an ornamental aquatic plant is
heavily outweighed by management costs.
Flooding may also occur. It is very likely that
these impacts would occur when the plant is
introduced.

as A2 in 2005.
Type of measures
Measures in NL (aimed at
containment) included the following:
Prohibit import of nutsedge
infested PM;
Surveys;
Official declaration of infested
status of fields;
Prohibit the use of infested fields
for the production of PM other
than seed or cuttings;
Destruction of infested PM.
Cleaning of machinery used on
infested land.
For eradication purposes effective
measures did also include a ban of
growing all rootcrops on all land
declared nutsedge infested (lifting of
the declaration after at least three
consecutive seasons without any
visually presence of nutsedge).
Import controls (no trade of plant)
