Leather Jackets - update

We've had reports from one of top agricultural pesticide manufacturers which we thought may be of interest.

  • Autumn last year leatherjackets were reported at their highest for many years
  • Now they are warning that there is a high risk of damage as the size of the grub is larger than usual for this time of year.
  • Initial reports are indicating high levels of populations in grass at this time of year
  • People should keep their eye out for any damage and take action if needed

Leatherjacket activity is often indicated by large numbers numbers of rooks & crows etc feeding on larvae. 

A solution to these wee beasties for managed amenity turf is Pyrinex coming in a 5lt pack - which can be applied now and used for up to two treatments in the year.

If we hear any more we will keep you updated.

  • I have a customer who is having a complete garden renovation, and i'm planting the borders when the landscapers have finished. - I got an email to say that I would need to plant badger proof plants, as they'd ripped up the newly turfed lawn, - i'm presuming they were after chafer grubs brought to the surface by the old lawn being removed?

    I've never known badgers destroy plants, unless they were in the way of their paths, - anyone else with experience of anyting not to plant?

  • interesting. a lawn ive just sprayed with moss killer has visitors and im wondering if they are feeding for these , not just trying to dig holes ! ?

    is it toxic to Bees ?

  • I have often experienced them digging up new plants and trees, but it is to get to the bugs, worms etc that have been disturbed by our digging the soil. It seems to be especially prevalent at this time of year. Just check each morning and replant before the usually undamaged plant dries out. I think they have a target meal rather than speculative digs, so if successful at first they will have done with their dining at that restaurant and move on to another. Not much comfort when they pull up 200 whips though!
