Advice needed - New Zealand flax

[bubblensqueek]

My 6 New Zealand flax all have lots of white stuff on the bottom root side of the plant and inside the leaves - mainly towards the bottom. I've noticed quite a few grey and white bugs as well, teeny and bigger ones. I'm suspecting mealy bug! The plants are in pots and get plenty of daylight. There are lots of remedies mentioned on the web - has anyone had this problem and managed to solve it?

Thanks!!

My Grandad grew flax during the war, for parachutes... got an OBE for it too

Sadly he's no longer with us so is unable to help :(

My ten year old NZF got just the same thing last year. I spent months chucking one chemical after another at it. I hoped that the bad winter would kill them off but 'fraid not. Final solution was somewhat final.
