Leather jackets

[herman]

I sell a product called Greenland. You can only get it from us. Refer to previous posts. Works on LJ's, Wireworm, Slugs and Nematodes. Is a mixture of a particular type of Garlic and Salacilic acid (Aspirin).
It is a "crop tonic"! I use it at 1.0ltr/ha (5ltr @ £100). To reduce the problems of hard water I also supply Reactor water conditioner along with it plus instructions for use. This has worked from Orkney to Wales without any problem.
One thing it doesn't control is Cutworm larvae but there is at least one other method of shifting them.

Could this be used on potatoes for slug control ?

Yes but Breakthru better on that front especially after dehaulming.
Greenland would also have a big effect on Wireworm plus an effect on nematodes but rate would need to be higher due to dilution effect of that amount of soil.

Breakthru, have you checked your PMs recently?

I have poor spring barley establishment in notill long term combineable
slugs slow growth or leather jackets or combination of both
i do find a lot more leather jacket in fields compared to pre notill when never saw any in cultivated land

Use the old Dow method. Piece of 4" pipe battered into the ground about 9" and then fill with salt water. Next morning lift out the pipe and you will find the dead bodies on the surface for ID.

They're hardy things, i'm not sure a roll would do much at them in all honesty, if it did enough to squash them it would probably compact the ground something chronic..

your not trying to "squash" them. your trying to firm up the ground so they can't burrow back into it and they "dry out" in the sun and die

Yours must be different, ours don't come to the surface just graze an inch or so below.

@Breakthru do you have any data supporting the effectiveness against leatherjackets?

How does it kill them?

Was thinking the same a couple of days ago, I have a couple of patches in some spring oats and wheat, did wonder if leather jackets are responsible, willneed to put some slug traps out to see what is responsible

Entered into CRD under another name years ago against slugs. Anything that says kills will be highly unlikely to get out. Both it and Breakthru for slugs with anecdotal effects on flea beetle in OSR are crop tonic and foliar feed respectively.
The reason I was mentioned above was there was a whole thread on LJ's previously.
The thing I find most interesting is like everything else on the internet 99% of people only post to complain something doesn't work. It seems very difficult to get the many people these things work for to post a positive result.
I sell to a lot of people on this forum but also through word of mouth because of this forum. Look at the number of members and the number of posters and that may give you a clue.
How it works, bit of a mystery, Told it is a particular type of Garlic from central France. Maybe they don't like Salicylic salt/Aspirin and or it is the synergy between the two??
There are trial results but due to CRD they are under wraps.
We started many years ago using it in organic grass as not being able to use Dursban. Then certain other clients preferred it to Dursban due to its Chernobyl effect on wildlife and sprayer operators.
As there is no alternative we don't need to spend a fortune on data gathering, you try it if it works you will use it again, simple as.

Could you tag some members that have used it and see if they will comment on how effective it was for them

Where ever I look find leather jackets
got borage ( not a lot coming up too cold and wet in May ) find the leather jacket easly
in spring barley also

Will this breakthrough product kill cheafers?

Will this breakthrough product kill cheafers?

Greenland doesn't touch Cutworm larvae unfortunately so doubtful if it would
do them.
Two methods could possibly work. On grass use salt, may drive them to the surface where the birds will get them. Try the trick with the pipe driven into the ground and filled with some salt water.
Breakthrough has been used in OSR stubbles where both lJ's and Slugs were present. Only heard it done a couple of times but what happened was the 2kg/ha potato rate was used in the evening when slugs were active.
Defo on the slugs but what happened was it forced the LJ's to the surface where crows et al devoured them. Seems they don't like the soil conditions same as slugs. There is also anecdotal results on Flea Beetle. They come in have a quick nibble then move on as there is nowhere comfortable for them to hide.
We really don't have these mega problems up here so only working at arms length where very occasionally people let you know the results of what they have done.

Not sure if that comes under GPDR rules. My retail website keeps no database of clients specifically for this reason. Costs would be enormous.
There are people on here who have used it successfully from Orkney to S. Wales and no doubt they will watch LJ strings but whether they post or not is up to them.

Done a bit more research
crane fly lay their eggs on grass
my fields had spring barley volunteers last autumn so could have attracted the crane fly
am now going to investigate other fields
may have to look or what is used as cover in the autumn
or was 2020 autumn just a bad crane fly year
and the cold dry April cold wet May made us look in fields more slow growth

As a matter of interest in the autumn did you see many crane flies, if so do you remember if they looked small and immature or just your usual giant daddy long legs? Our experience 5 or 6 years ago was it was the small ones that caused the damage and they even created havoc in second year leys. Just before the demise of Dursban and pallets of it went to the West of Scotland.

There are two separate threads about LJ's here the other under cropping so suggest looking at both as if the replies seem a bit disjointed I certainly am confused as to what replies to make without repeating myself.

Are you sure that they are leather jackets not Bionamid (St Marks fly) larvae.
They are a bit longer, thinner and have bristles at one end, but very similar, if you are not aware of the difference you would just assume that they are leather jackets. look for big black slow moving flies on still days around St Marks day.
They are something that we are seeing a lot of in notill ground, but only seem to bother spring crops, especially game cover.

Use the old Dow/Dursban trial. 1ft of drainage pipe hammered into the turf 6".
Fill it with salty water and in the morning you will see Lj's, wireworm, slugs etc dead on the surface. Repeat across a large field. that way you can identify your problem or not as the case maybe.
