Haven't found the chemical formula for the main active ingredient yet but, here is some safety information on Pyrethrins https://www.plunketts.net/drione_m.pdf

Also look at this MSDS: https://www.prentiss.com/msds/pdf/655_489.pdf


I think that the latter MSDS says that Pyrethrins are Petroleum Solvents which means that chemically, these compounds are "organic" but, reading all the toixicity information; I would advise against using this product.

We have recommended using Neem Oil as an insecticide if you use anything at all. I tend to discourage the use of any insecticides, pesticides, herbicde or what have you because they are broad based killer and not only kill the pest organisms but, also the beneficials.

Not only that they kill the micro organisms that keep plant disease at bay and also work to build the healthy soil that plants grow in.

With the GMO problem that the world is currently facing companies engineer plants that will only grow with the use of herbicides, and other -cides which just end up (in the long term) degrading our soils, polluting our soils (and our foods) and not to mention the atmosphere.

Peachguy, you can make your own if you find you are truly in need.

Here's the others you can make for diseases and pests.

Of course you can use the Neem oil if you like.

I just thought it might be because Pyrethrins come from the chrythanmum flowers so to me it seemed natural and organic. Anyways were do you buy your neem oil? Also do any of you use BT, BTK ect. if so where can you buy them. I ask because the nurseries near me only barely sell any organic products the big department stores are finially getting fish emulsions and seaweeds spray.

Here in the US we can get Neem oil in Home Depot. I garden organically and haven't had to spray for anything in years. I have a small garden but it's chock full of many varieties of plants, many of which are natives, which attract lots of beneficials. I do grow swamp milkweed which gets aphids, but the ladybugs take care of those. I do get Japanese beetles and pick them off and put them in soapy water. I used to have a big slug problem when I first moved in here 18 years ago, but since I don't use pesticides the toads have moved in and control the slugs. Once you go organic it takes a couple of years for it all to balance out. I tolerate a bug here and there and the birds we feed gobble up many of the bugs and feed them to their young.

Hi peachguy,

it is important to consider the chemical toxicological information of a given chemical before using it; even Neem Oil has it's draw backs so, be sure to read the Sticky on Neem Oil in the General Forum before making your decision.

Plants often secrete what are called "Secondary Metabolites" in very small quantities to ward off pests of all shapes and forms. But, when we mass produce these chemicals and use large amounts of them, they become a problem.

Even Neem Oil has it's drawbacks especialy on North Americas Bee Population which, has enough problems right now. If you do choose to use Neem Oil, please only use once a week at the most.

Oh, and given that Pyrethrins are synthesized by a plant, they are almost surely "organic" in the chemical sense of the word; meaning that they are made of a carbon backbone however, this does not make a chemical safe and organic in the sense of organic gardening. Many chemically organic compounds are highly toxic and not to mention carcinogenic.

Anyway, just some more information for you.
