I purchased some Malathion several years ago from the USA and instructions said after spraying your fruit n veg, you could eat with in 10-14 days

Re: Is this root mealy?
Here is perhaps a new method to get rid of root mealy.

I have not tried this but I definitely will if/when I have some. Might be worth trying for other soil pests as well.

Re: Is this root mealy?
Hi All
Many thanks for the responses - greatly appreciated!
I spent a couple of hours inspecting the roots on each specimen and did not see anything akin to the photographs posted which is a huge relief.
And that method does seem logical and is something I have done before - if not the heat, surely completely submerging the plant for ten minutes in water (having washed off the soil etc) would kill the pest just through a lack of oxygen? A cumbersome method perhaps.
I did find a stray mealybug on a jade a while back, and just washed the plant (with a shower head) and washed away all soil, and sumberged the jade completely under water for ten minutes or so, and have not had a bug since, and the plant seems perfectly healthy. Probably a bit gun-ho?
Interesting anyway; in my research it seems there is no one size fits all approach to pests, and everyone seems to adopt their own particular nuance and approach.
Thanks

Re: Is this root mealy?
I wouldn't hold out much hope of drowning mealybugs. Lots of insects can survive hours, even days underwater. Spraying with soapy water is certainly effective though.MrRazzell wrote: ↑Sat Oct 27, 2018 2:43 pm Hi All

Re: Is this root mealy?
Absolutely. I have recently made a home brew concoction of neem oil, washing up soap, and 70% alcohol and it has worked wonderfully. I followed this up with plant invigorator (which actually I now realise is an overpriced soap mix?) and I have not seen anything akin to a pest since - also no damage to any of the specimens. Indeed, my Andromichus' have thrown out several new leaves apiece which may have something to do with the plant invigorator.habanerocat wrote: ↑Thu Nov 01, 2018 1:47 pmI wouldn't hold out much hope of drowning mealybugs.

Anyway it is much colder now so hopefully Mother Nature will play her part

Re: Is this root mealy?
What temperature do root mealy bugs die out (if they do) and the upper plant mealy bugs?

I don't know, but I'm sure it's way below what the plants can stand!Cactusgirl wrote: ↑Tue Nov 06, 2018 8:16 am What temperature do root mealy bugs die out (if they do) and the upper plant mealy bugs?
There was an article years ago, I think in the journal (possibly the old GB or National societies pre-BCSS) which described placing cacti in hot water for a specific time, which killed mealies. The temperature/time to kill mealies was critical, since anything much hotter or for longer would lead to plant damage or death. Anybody know the details of that article?

Re: Is this root mealy?
The hot water method is very interesting. I'd be glad to hear if anyone here has tried it and whether or not it was successful (getting rid of bugs and not damaging plants).
