Yes that will work

I'm not a good gardener, mostly because I'm lazy in not wishing to waste my time in that respect, but also because if there were such a thing as the opposite of green fingers I've pretty much got it locked. Still I appreciate the talent of my friends, family and neighbours who turn their gardens into horticultural wonderlands of colour and edibles.
There's a whole world of flower shows and vegetable competitions out there that I have no real interest in other than wandering through mostly thinking my, that's pretty, or my that's huge, I know there are certain criteria that have to be met too, though the rules are often obscure, I'm also told that jealousy runs rife in those communities whose idea of fun this is. I was brought up in a North East of England where prize leeks were grown and exhibited and learned a few of the tricks fierce rivals were prepared to go to to wreck a competitors chances, so this story doesn't surprise me at all.
Still I wouldn't have thought that the best way to deal with a worthy champion of the art would be to ask him not to bother anymore.

Telegraph.

It is the ultimate accolade for a keen vegetable grower – a 73-year-old has been told not enter his village gardening competition because he is too good.

David Stirzaker has been asked by the organisers of the North Cadbury and District Horticultural Society, in Somerset, not to exhibit his produce at its annual show, because his impressive record at the event is discouraging others from taking part.

Mr Stirzaker – who has won 12 cups at the show in just four years, for his prize-winning carrots, parsnips and tomatoes – has pledged to take the matter to the Royal Horticultural Society.

"This is my hobby and I have been supporting their show for four years. I find the request very insulting – it is a competition so I would have thought it is down to other growers to try harder if they want to beat me," he said.

"I want nothing more to do with the society. I won't be showing there again and I have told them that they can come and collect their trophies."

You can't really imagine it happening in Formula 1 or any sporting activity, champions are champions after all and I doubt that he's putting off others from entering, simply setting the standard of what it takes to win. I might be wrong, but this has all the hallmarks of a jealous rival nobbling their competitor because they are better.
