Derris powder/liquid
 

Hi to all as this is my first posting to this Newsgroup, may I
congratulate all contributers for providing over the last couple of
years or so I have been lurking here both entertaining and informative
reading .
The reason I have come out of lurk mode is before I rush out and buy a
quantity of Derris powder/liquid, I would be interested to know what
other gardeners experience of this product is, which is more effective
liquid or powder, and what is it's overall effectiveness as a Organic
Pest control, suggestions for any other home made or branded Pest
control appreciated .

Derris or Derris/rotenone is not recommended for regular use in organic
gardening. It is given 'qualified acceptance' for help with problems
during conversion from non organic practices to organic. Pest and
disease management and control in organic systems are based mainly on
prevention, good hygiene and encouragement of natural predators,
pesticides are not used.

My experience has been negative. It's not very effective, even in
liquid form, and the power is a waste of time and money. I found
liquid pyrethrum moderately effective, but you can buy only the
synthetic form, but liquid soap (Savona) seems as good as anything
and a lot more economical. The great advantage of liquid soap (or
washing up liquid and methylated spirits mixture) is that you can
drench the plants without harm to humans (or usually the plant).

You might be interested to know, that I for one, suspect that this newsgroup
has one of the largest groups of lurkers in the newsgroup world. I certainly
get a lot of response to my sig in this newsgroup. :-))
