White flies and washing up liquid?

 The Palmolive brand washing up liquid was effective against the black
fly on the broad beans, one or two are appearing again now though so
time for a respray.

How about white fly? Some of young brassica plants are looking poorly
and investigation shows some of them have white fly underneath the
leaves. Will washing up liquid be effective against them too?

Bit of a fiddly and wet job if you are not careful, but we found that going
up from underneath and pointing up with the hose shifted them :-))

Last year I had a huge whitefly infestation with all of my brassicas.
I think it was because I noticed them too late and could not keep on top of
them. I took remedial action by using a car vacuum cleaner. ALL of the
brass. suffered and were not really worth harvesting, but the vac worked a
bit
This year I have used a systemic bug killer on all brass. when planted, at
2" tall.(I grew all from seed). They look good now, but after spraying
looked sick with yellow leaves. We will see what happens after the second
dose. It says on the label to use every 4-6 weeks.
I HATE using chemicals but I aren't watching my garden turning into a haven
for unwanted, disease carrying flying insects again.

If you are interested the product I have  is a Bayer Garden product called
"Provado Ultimate Bug Killer Concentrate2"

BTW if you nip the tops out on the broad bean plants after some pods have
set the blackfly will be gone and also will encourage new pods.

I hope this helps, David

Do you rinse it off after, say, a couple of hours, after it has had time to
kill the bugs?
One of the gardening gurus on the radio here suggests that.
I have an infestation of aphids on my redcurrants and I will spray them this
w/e with soap, perhaps beefed up with a little pyrethrin.

I've never seen aphids on my redcurrants.  Maybe there are just tastier
things for them to live on.

The problem with my recurrants is that I came back from a few days at my
parents and the bloody birds have stripped the lot.  :'(
