Looks like I have succumbed to this problem again!
I have noticed some of my sweet pepper have curled up at the growing tip whereas some other have not.
I think it is a result of an experimented on some of them where I altered my compost mix.
This year I am using Humax M-P and I have found it to be very fine so I thought I would add some seived rotted down horse muck which incidently had the consistency of a nice chocolate spong cake, I thought this would bulk up the fine compost and make it more loamy.
AS far as my plan went it did just that and it turned out to be a nice compost mix but it never entered my head that there might be traces of weedkiller in the muck.
When we first arranged with the stable owners to take their surplus muck we discussed with the owners about aminopyralid and they said they would never get involved with this stuff so much so the use shredded cardboard as bedding rather than straw/hay, so we agreed to take as much as they had and even set up a tipping area with easy access to save them tipping problems.
This was around 4-5 years ago and things have been fine that is until I conducted this experiment.
My guess is the stable have bought in some contaminated feeding from somewhere and the horses have eaten it with no ill affect, but sadly it would seem their droppings become affected in the process.
This is what my affected plants look like;
Not the best of pictures but I think there is enough detail to show you what has happened.
I thought it might be an aphid problem as some aphids can cause leaf curl and I did have some whitefly earlier on in the season, but I am fairly certain this is not the case as the new growth is appearing curled up as it opens and there are no aphids around.
Most of them are on my yellow sticky traps:
Even the spiders help with my insect control as you can see here:
(I extricated this bee so it is now flying around my garden)
Sorry for the lecture but I thought some of the newbies might be interested in the scenario so I put it up.
Just think of it as another one of those trials and tribulations we gardeners have to put up now that the EU govern pesticides & herbicides!
