Rhizoctonia solani and black scurf are tuber diseases capable of inflicting severe yield losses if crops are left unprotected, but in Emesto Prime DS (penflufen), growers have a tuber treatment delivering unsurpassed levels of control.
On every measure, be it black scurf incidence on tubers, crop emergence, final stand, tuber size distribution or marketable yield, Emesto Prime DS delivers substantial positive effects. It has also shown useful reductions in silver scurf, while a trial performed at Fife by Scottish Agronomy in 2018 served to substantiate its claim as the best protection against black scurf.
Incidence of black scurf post-harvest depending on tuber treatment
Reference: Scottish Agronomy, Fife trial, 2018
The trial used heavily infected seed with tubers from the untreated crop suffering a 47% incidence of black scurf. Tubers from the Emesto-treated crops were found to contain no detectable levels of black scurf compared with 2% for Monceren DS and 12% for flutolanil (DS formulation). The trial highlights the reliability of Emesto Prime and its role in delivering crops with a quality skin finish within the parameters demanded by the market.
To use Emesto Prime DS growers will need to ensure their planters are fitted with a suitable on-planter powder applicator and that the control box features the necessary settings.
Emesto Prime has an application rate of 1kg/T of planted seed and must be applied through an on-planter powder applicator. Applicator settings should be adjusted for the Emesto formulation, which is separate to the Monceren setting, even when applied at the same rate. Where settings need updating to include Emesto Prime DS, growers should contact the machine manufacturer to arrange it in time for planting in the coming season.
