is that what ebay use?

GB Potatoes has confirmed it will not proceed with an Emergency Authorisation (EA) application for the fungicide, following technical discussions that concluded any approval would deliver little practical benefit for growers.

The decision follows the planned withdrawal of mancozeb from use in the UK at the end of the 2025 season, raising concerns over blight control at a time of increasing disease pressure and resistance risk.

GB Potatoes said it assessed all possible routes to support growers through the transition, including whether an EA could allow limited use of mancozeb on potato crops in 2026.

Scott Walker, chief executive of GB Potatoes, said the option was explored in detail. “Following the announcement that mancozeb would be withdrawn from use in the UK at the end of the 2025 season, GB Potatoes explored the feasibility of progressing an Emergency Authorisation (EA) application to allow a continued use on potato crops,” he said. 

its a fungiside NOT Hazadous material 

I don't know how Ebay came to their decision but, it seems that emergency authorisation was ruled out and the product was banned from sale in the UK at the end of last year.
