Default Natural Insect Repellants

I have a backyard vineyard of about 100 vines.
Does anyone know of any plants that are natural
insect repellants that I could plant between the
vines. I do not need a product I can eat but
something that is pretty would be an added bonus.

Marigolds are old stand-bys for that kind of thing, the smellier, the
better.

There seems to be some dissagreement on this:

Have you ever seen anything said on the 'net that DOESN'T have
disagreement over it?

Yes, of course. However, there is scientific research regarding the
species Tagetes spp. and it is and was used for root knot nematodes
not flying, crawling or jumping insects.

Not true. Marigolds attract spider mites. There is only one variety
of marigold which helps prevent root knot nematodes IN the soil.
Where did you get "the smellier, the better" from?

The way farmers do it in organic method farming is to plant catch
crops for whatever insect. Here, for example, aphids adore the young
Guara lindheimeri, so those get planted in order to then attract lady
beetles...etc.

I have never ever ever ever seen a spider mite on a marigold. Ever. I
say this in a seriousness.

shrug Who knows? I have not yet the ability to remember the source of
everything I have seen and heard and read and watched. I'm working on it
tho'. I hope to master it before I die.

So, by that logic, then Marigolds COULD work under the right conditions,
right?

Spider mites are microscopic. They cover from top to bottom any
marigold I've ever planted. They are used in farming as catch crops
to draw the attention of spider mites. I say this in all factualness
(not a real word I don't think)

If you don't remember where you heard something why would you pass it
on as fact? One thing I'm learning is to not advise based on my own
BS, but to advise based on the facts. I believe your heart was in the
right place, but I do not think you gave good information regarding
this subject.

Not in the way you said they work. They do not repel insects, rather
attract them thus farmers use them as catch crops. So, the answer to
your last question is no, by no logic do marigolds work under the
right conditions to repel insects.

Actually, I said it tongue in cheek. *sigh* The printed word is SUCH a
limiting medium.

May all your authoritive advice always be right on the money and may you
never, ever, EVER make a mistake. Carry on!

In the UK, gardeners who grow tomatoes and basil in glasshouses,

whitefly.

Wrong. C. coccineum is NO relation to Tagetes. You are also wrong
about it being the "leaves, is the pyrethrum." Pyrethrum come from a
Chrysanthamum coccineum plant and it is the crushed flowers where the
poison is, not the foliage.

Yes, and marigolds are used as companion plants with tomatoes, and
they do not contain pyrethrum.
The main point is that they deter certain insects that like tomatoe
plants.
Marigolds are not an insecticide. They are a deterrent.

Oy, there is ONE marigold which can control or help to control root
knot nematodes. Otherwise, they are useless. You'd be much better
off planting garlic or basil with tomatoes.

The active chemical occurs in several members of the compositae
family, including, chrysanthemum and marigold. See

http://www.patentstorm.us/patents/54...scription.html

which is much too long to reproduce here, but here's a snippet

"Industrially, pyrethrum extracts are obtained by extraction of dried
pyrethrum flowers with hexane followed by dewaxing and decolorization to
yield a mixture containing approximately 20% pyrethrins and 80% inert
plant materials or solvents. This technical extract is registered with
the Environmental Protection Agency and is a standard item of commerce
used for formulating numerous end products. Flower production is
centered in Kenya and surrounding countries, with some production being
attempted in Tasmania and New Guinea. While pyrethrum flowers are not
grown commercially in the United States, some of the Compositae
(daisies, marigolds, etc.) in U.S. gardens probably produce these
compounds. There has been an effort to cultivate C. cinerariaefolium in
Oregon and Arizona but this is not yet a viable commercial source. "

Janet.


All this says is that no form of Tagetes has been formulated as a
viable source, so you, me, nobody anywhere has ever used any form of
Tagetes to kill insects. Pyrethrum FLOWERS is where the compound is
found, not the leaves. Your post proves it.
