Yellow potato cyst nematode

Host plant symptoms are not a reliable means of identification since symptoms of attack by Globodera species are not specific. Patches of poor growth may occur generally in the crop, sometimes with yellowing, wilting or death of foliage. Potato tubers may be small. Mild infestation symptoms suggest the plants may be under stress from water or mineral deficiency. On heavily infested plants the cysts on the roots are clearly visible with the naked eye. No tuber symptoms have been reported.
