I have just picked up an ancient book on the control of wireworm recommending Bromophos. However a brief search on the 'net suggests it is now no longer available.
My potatoes show signs of wireworm and I'm wondering what the commercial growers do about this problem. What do they use?

I'm sure they have sprays to deal with this which would not be available to the general public.
Just dug out my Dad's old gardening book published in 1949 (they year of my birth) and it recommends "Eradication of wireworms cosists of employing a reliable soil fumigant such as Napthalene inthe Autumn when the plants are dormant ! ! ! Cheers, Tony.
Wireworm is not normally a problem to commercial growers as it is usually a problem associated with planting after long term grass such as when you dig up an old lawn
it is normally a problem in cereal crops after grass and can be controlled with insecticidal dressing of the seed
There is nothing you can do when they attack potatoes although nematicides used to control eelworm would probably give good control of wireworm
These products which are highly poisonous can only be used by approved operators and are not available to amateur growers
Naphtalene? That's Moth Balls? They should easy enough to find?

Try growing Caliente Mustard green manure over winter - it's supposed to have a bio-fumigant effect and which can deter wireworms apparently.
I grew it last winter and had a much better crop of spuds this year!
When did you last try to buy old fashioned type moth balls? I think they have been removed from sale by the nanny police.

hmm - actually I have never bought them. My nan has some in the wardrobe for storing winter coats, but they could well be years old. I did see them for sale in Tunisia on the markets everywhere, but that doesn't really help (unless you fancy a holiday there).
I didn't know they have been taken off the market? I rather liked the smell, to be honest. Why did they stop selling them?
