I blasted mine with garlic water y'day, it's had no effect whatsoever

Now what did I tell you?!

Whitefly breath through a lot of little holes down their body called spiracles. These can easily be blocked when a detergent-based spray is applied as it causes the wax on their bodies to become runny and cover the holes. It also causes their waxy wings to stick together or stick to a treated leaf. Now you know

Right then, if the garlic didn't work I'd best get the extension and get the hoover out there tomorrow

I take it back. Just went out there, shook all the chillies, and nothing. No clouds of whitefly at all. Checked under the leaves: lots of whitefly, but all deaded. Result !

Just got a wood burner and the ash that's left behind i spread over my cabbages and sprouts and does the trick and its organic as well

So would a strong solution of washing up liquid sprayed on the underside of the leaves block them up then.
It could wash the black stuff off at the same time LOL

[Fruit&2veg]

Washing up solution is definatly quite effective on blackfly, but I must admit, have not found it work so well on whitefly, although its definatly better than nothing, and certainly worth a try.

[Florence Fennel]

Thanks TS, I'll give that a try over the weekend.

It tends to kill the leaves too though

Got a recipe for your whitefly slaughtering garlic water, TS?

[Two_Sheds]

1 bulb of garlic, crushed
boiled in a pint of water
strained into a sprayer

I'll be doing another spray today as there're a few more whiteflies today, probably just hatched

In the words of Victor Meldrew.... 'I don't believe it!' Two years of messing about with different formulations of garlic and nothing....

What variety did you use TS?

Agree... Brassicas have a thick wax coating which is temporarily removed by detergents. This exposes them to the elements and they dry out.

have just harvested some cottagers kale ........so much easier to scrub than the crinkly stuff... just thought I'd say
