80% of my Snow cauliflowers and savoy cabbage have cabbage rootfly. Can they any be recovered? And can I save the remaining few? I have been told to try diluting a little of jeyes fluid and watering the base of the plants which I will do tonight as I have just watered them.
Our allotment shop has said even all chemicals for this have now been withdrawn. All ideas welcomed.
Sickening - no recovery that I know of.
Save? Don't know, but I would have thought that if the 'others' haven't got it yet, they won't.
Depends on how strong the plants are growing if they are established they may get over it
sorry to hear that KT, it's so frustrating losing stuff like that, we have to contend with rabbits and badgers as well as flippin insects ::) . The badgers really enjoy sweetcorn . Will cabbages planted out now be vulnerable to root fly does any one know ?? (If I am hijacking please redirect :-[....
KT,
It's very late for cabbage rootfly (usually June).
When did you plant - appreciate you're up north!

They have been transplanted for 6-8 weeks, they are about 8 inches diameter from leaf to leaf.
I have been given 8 savoy plug plants today. I've put them in the ground with a little rhubarb leaf in the bottom, then surrounded the plant with lime.
Hi KT,
sorry to hear about the dreaded root fly, did you not use cabbage collars? I cut unused rubber carpet underlay into 5 inch squares & then cut a slit in to the middle & sit it around the base of the plant. Another thing I do to combat that other scurge, club root, is transplant the seedlings into compost that I sterilized 3 days previously with armillatox. I know it`s not supposed to be used for this but I ain`t dead yet. When the pots have filled with roots transplant into a bigger one again with sterilised soil. This works for me , & I have not had any club root or cabbage root fly problems for 3 years.
Adrian.

Managed to keep about 10. They appear to be healthy enough.
Just a thought here, and put me right if I'm completely off the mark, but does anyone think it would help to put a dollop (that's the technical term for a large plip) of vaseline around the base of the plants when they're young to keep the fly off.
Would this harm the plant?
Would this harm us when we eat them?
Mine are only about a pencil thick at the stem - when is it the fly is likely to attack?
Hi, sorry to read about your problem, I always puff some derris powder in the planting hole and on top of the soil when planted, this seems to work.
Bit late for this advice but it might stand you in good stead for the next time.
When planting out (all brassicas) I form the hole and flood it with an Armillatox mixture (same smell as Jeyes).
Alternatively I plant the plant then flood it with the mixture (it is less messy this way)
I think the smell lingers and keeps them away
oh no just looked it up in a book :o I think i,v just planted some s greens with the grubs in the roots. I grew them in pots in my garden and noticed the grubs
when a rootball was exposed where would i get this armillatox? and if i watered it on then put a collar around the stem would it stop them from climbing up? or are the collers to stop the fly going down to lay the eggs that turn into the grubs
marg
right I,v swotted up on CRfly and inspected the two ailing plants and found a couple of grubs on one of them, think i might have got the others when i discovered them!have drenched all of them in diluted liquid derris so fingers crossed. the seeds were sown in august so were not around in june ???
i,v spare one in the garden which are all healthy if small so am potting them on to fill the gaps
thanks KT if you hadn,t posted about it I,d have forgotten about them and let them run riot
