do you have any data on this? or is this just supposition on your part?
i'm
not doubting you, mind you, i'd just be interested in how you came to this
matter-of-fact conclusion...

Short story: 30 years of gardening, and reading everything I can get my
hands on.

Long story:

Lots of reading, and basic knowledge of research methods and statistics are
all you need to understand the issue.

1) When testing a new medicine for efficacy and safety, results are not
valid (or legal) until the stuff has been administered to a large enough
target population. Further, a drug company cannot test a medicine on rats,
and then claim it's safe for humans, simply because we're both mammals. For
medicines, this is considered common sense.

2) No common sense: Chemical companies insist that certain agricultural
applications are safe for human food crops, but according to good practices,
as described in #1, it is impossible for them to do so. They cannot test on
a human population. In reality, they do: You and I are the test population.
Unfortunately, nobody is collecting the results and it's not a controlled
study.

3) I believe it was 1970 when the federal government eliminated the
requirement that pesticides fully disclose inert ingredients, and for
manufacturers to test them, in addition to the active ingredients. These
ingredients are the ones which help keep the active chemicals in suspension,
and help them stick to whatever you're spraying them on. They often contain
petroleum distillates whose effects are not known. Check some containers
next time you're browsing chemicals. You'll find that these inert
ingredients usually comprise the bulk of what you're applying to your
garden.

4) Because too many people believe labels, and do no further research, they
believe that "naturally derived" is the same as "natural". So, they believe
that pyrethrin is identical to pyrethrum. The latter comes from flowers, but
is rarely found in pure form without "inert" ingredients. The former has
been doctored, and MAY be less safe, but nobody really knows. Even the pure
form of pyrethrum is probably unsafe for consumption.

5) Pesticides come back to haunt you in lots of ways. Example: Much of it
ends up in storm sewers where it drains into water supplies. You're treated
to low doses of it constantly. It also ends up in the fish you eat, no
matter where it comes from. (No...farm-raised doesn't mean "pure"....)

You decide. By the way, do you know which "supermarket crops" are the most
heavily sprayed? Carrots (not really sprayed, but gassed or powdered") and
strawberries. Kids love 'em. Yum.

There are better ways to deal with bugs.

- For plants whose leaves you don't eat, a few holes is not going to kill
them. Don't worry about the bugs.

- Many bugs are here for a short time, and then gone. If they nail a few
peppers, throw away those peppers and watch the remaining ones. There's an
excellent chance you won't see those bugs at another point in the season.
Sometimes, I pinch the flowers off a portion of my pepper plants until later
in the season, so they'll make fruit at a time when there may be less pests.

- Losing 20% of your lettuce, spinach, or swiss chard? Plant 20% extra for
the bugs. Cost: a nickle?
