Rhizoctonia control is set to become much more difficult for potato growers with news of a second seed treatment being withdrawn, just weeks after the loss of Monceren. Adam Clarke reports for Farmers Weekly.
EU regulators have recommended the withdrawal of penflufen, a fungicide contained in the powder seed tuber treatment product Emesto Prime DS. It is used to control Rhizoctonia solani, which causes stem and stolon canker and black scurf in potatoes.
The revocation – which has yet to be formally adopted by the EU Commission – follows work carried out by regulatory authorities in Poland, the rapporteur state for penflufen’s recent reassessment.
Outcomes led to the active ingredient’s “reclassification” and consequently Bayer Crop Science’s marketing authorisation for penflufen-containing products is set to be withdrawn.
The anticipated revocation will not affect the marketability of crops treated this season.
