Default Orthenex

Well I guess both options of fumigation are out as I can't run!!! *G*
(Arthritis)
Oh & that CA thing!
My plants have scale & mealy bugs & I have used everything from the
409/oil recipes
WP & the $$$$ Enstar & Mavrik to no avail.
The most effective item lately has been a product that has 1%
Pyritherins (Safer brand)
So I need to look for it in a concentrated form as it is around $5 for the
normal spray bottle.
Anyway thanks for the info,
Cheers Wendy

Wendy, there just are not that many fumigants left on the market. From
what is available to me here in Va there are two options. The first is a
series of products from the Whitmire Corp which are total release
aerosols. Pop a can and run and while you are eating dinner the whole
greenhouse gets treated. The flavors available a year or two ago where
dursban (restricted), decathion, acephate, pyrethrum, an IGR, and Taistar.
The label allows air mixing, i.e. pop two different cans and run.
Although there could not be an easier way to treat a greenhouse, I found
that I always got a better kill if I just strapped on the backpack and
sprayed the same chemical. Maybe my greenhouse are just too crowded
causing incorrect dose or coverage. Don't know and I only use the
Whitmire products when I find a problem and know it will be a while before
I get a chance to spray.

The other option is smoke. Light the can and run. I think all of the
smoke products are restricted use and the last time I looked only came in
two flavors; DDVP (organophosphate) and nicotine. I have found these
products to be very effective against whitefly, aphids, and thrips. But I
have not had much luck with these products against scale, mealybugs, and
fungus gnats. I do not think smoke is an option in Ca.
