Potato Cyst Nematodes have been known to occur in the UK for nearly one hundred years. They are the most problematic pest of potatoes and can cause a severe yield loss.
Samples of soil should be taken using a soil corer.
Fields should be sub -divided into blocks of one hectare or less, sampling in a grid using a ‘W’ pattern is deemed the most effective, across the direction of cultivation.
Approximately 1.5 – 2 kg of sample are required by the laboratory for analysis, if a sample is deemed lightweight we may contact you to discuss further action.
For a 1 in 6 crop rotation it is suggested that at least a 200gm sample be analysed
The preferred sample weight for PCN analysis is 1.5kg and for PCN/LOAM analysis is 2kg.
Bags can be supplied and posted out.
