Is it true that derris dust/liquid will be a banned substance from the end of this year? I was earwigging a conversation this morning and wondered if it was gossip or truth?

Tis indeed true. -
So much for organic pest control then!
I thought it was made from some kind of jungle shrub and was comparatively safe, but I may be wrong?
Having said that Nicotine used to be recommended as a pesticide not too long ago, and it was organic!

I've found an article on the web from Harrods Horticulture giving details:-

Organic Insecticides
A quick rummage around a typical gardener's shed will uncover various forms of derris, the well-known organic insecticide - but all that is set to change next year with the proposed outlawing of the product.
Rotenone - the active ingredient obtained from the crushed root of the derris tree - has been linked to the progressive brain disorder Parkinson's disease, and a subsequent investigation by the Pesticide Safety Directive (PSD) has led to the decision to withdraw all derris-based sprays and powders.
Although no definitive date has been set for the removal of derris from the market, sources claim that products will be available until September 2009. This will give organic gardeners plenty of time to find new artillery for the constant battle against garden pests such as aphids, caterpillars and flea beetles.
Among the products to be targeted are Liquid Derris and Derris Dust, but organic alternatives do already exist in the shape of sprays containing fatty acids, plant oils and pyrethrums. Derris itself has been used in the amateur horticultural sector since the mid-19th Century.
According to NHS statistics, Parkinson's disease afflicts up to 120,000 people in the UK'My Majesty made for him a garden anew in order

Hi Peeps.
What they didn't say was that the tests were done on lab rats and they were injected with the stuff daily for 5 years before symptoms occured.http://norm-foodforthought.blogspot.com/

I did 'till I found out yesterday that they tested it on rats. I threw it in the bin this morning.
I don't see the point in testing on animals to see what effect a substance will have on humans. I think they should test on humans. Start with politicians, move on to lawyers, then accountants...

Most good garden shops will sell derris and pyrethrum.
There are many different makes of both and mixtures of the two are stronger than either when used separately. They are capable of killing caterpillars and a range of different pests such as aphids and others which are listed on the bottle.
They are sometimes mixed with lindane and other organo-chlorine compounds and these ... are not organic.
Derris is sometimes available as a dust ‘derris dust’ and is very effective against the fleabeetle which eats holes in the leaves of brassica plants and radishes.
Do not let this substance trickle into your fishpond as it began as a Malaysian fish poison.
Also, if you keep bees and have to spray anything in flower, use pyrethrum or nicotine in the evening and it will ...be harmless by the time your bees start work in the morning.

Nicotine is good to protect an area from termites. Say if you have a stinking old ashtray of filthly butts you could boil it up in a tin can being careful not to breathe it in or get any on your skin and when its filthly and black and revolting sieve out the butts and pour a ring of it around the base of the post or plant suceptable to termites and apparantely it works. I wouldnt go eating any produce though, more for ornamentals or garden structures I'd say. Whats the alternative? Treated pine or creasote. Is that toxic or what?Originally posted by Snadger View PostSo much for organic pest control then! I thought it was made from some kind of jungle shrub and was comparatively safe, but I may be wrong?

Thats why Victorian gardeners could only smoke their pipe in certain greenhouses they wanted fumigating with nicotine.
Also the threat of tobacco mosaic virus stopped them from potting on or taking cuttings of certain plants whilst smoking!My Majesty made for him a garden anew in order
