Farmers given more time to dispose of Vydate stocks

Users and distributors of withdrawn granular nematicide Vydate (oxamyl) have been given extra time to return and dispose of existing stocks.

On 24 December 2020, it was announced by the Chemicals Regulation Division (CRD) that the product would not be reauthorised for sale, distribution or use beyond 31 December 2020.

The news was a blow to growers of a number of crops, with Vydate offering control of nematode pests in potatoes, carrots, parsnips, bulb onions, garlic and shallots, where alternative options are limited.

The original date for the return of stocks from farms and distributors was 28 February 2021, but the CRD has now pushed the deadline back to 30 April.

Farmers Weekly understands this is due to national Covid-19 restrictions and severe winter weather across large parts of the UK, which have put additional pressure on supply chain logistics. This does not mean the product can be used in 2021 crops.

Following a consultation with stakeholders, the AHDB applied for an emergency approval for Vydate use against key soil-borne pests (see “Vydate emergency approval applications”).

This process is ongoing, with the final decision to be made by government ministers in due course.

Corteva told Farmers Weekly that adequate stocks will be available for redistribution, if targeted Vydate use is approved this season.
