Plant-parasitic nematodes are among the most destructive
plant pest, causing substantial economic losses to crops worldwide.
The golden potato nematode Globodera rostochiensis
(Woll.) causes severe yield losses of potato (Solanum tuberosum
L.) in many regions of Bulgaria (Trifonova, 1995, 2000).
Soil treatment with nematicides has been an established practice
for the control of cyst-forming nematodes of the genus
Globodera, though it is very expensive for the farming community.
In recent years, we have been observing an increasing
trend to use alternative methods of pest control based on
replacing chemicals pesticides by natural compounds.
