Apple is the most common crop cultivated in Resen
region, Republic of Macedonia. In this region, apple
powdery mildew caused by Podosphaera leucotricha
(Ellis & Everh.) E. S. Salmon, and apple scab (caused
by Venturia inaequalis (Cooke) G. Wint) are important
pests in apple production. Trifloxystrobin is fungicide
which acts against these pests and improves the yield
of agricultural crops.
We analyzed the presence of trifloxystrobin in two varieties
of apples: Golden Delicious and Idaret from two
different locations: Evla and Kriveni in Resen region,
Macedonia. Fungicide was analyzed in four apple development
phases, or from apple of the size a hazelnut,
to the phase of harvest. Trifloxystrobin is analyzed
by liquid chromatography-tandem mass spectrometry
(LC-MS / MS) followed by an extraction/separation
treatment with acetonitrile and the dispersive SPE -
QuEChERS - method. Obtained values are compared
with the maximum residues levels (MRL) according to
the legislation of the Republic of Macedonia. We made
a statistical processing of the data with Student’s t-test.
The analysis revealed that trifloxystrobin is present in
Golden Delicious on both locations with a concentration
within the range of 0.04 to 0.14 mg/kg, but mainly
on Kriveni location. In the Idaret from Kriveni, it is detected
only in early phase of apple maturing, while in
Evla there is none or is below the detection limit. The
value of t-test for Golden Delicious and Idaret from
both locations are 1,946173039 and 1. They are lower
than the critical t-value. That means that there is a significant
difference in the presence of trifloxystrobin in
apples from Kriveni and Evla.
After comparing the obtained values with the MRL it
can be concluded that apples from the two locations
are safe for consumption.
Key words: Trifloxystrobin, Fungicides, Apples, Golden
Delicious, Idaret.
