Has anybody used Grazers for Slugs& Snails or for Caterpillars?

Grazers Slug & Snails Deterrent Spray

I couldn't find an ingredient list.

Has anybody used this?

 

I've still got some from about 5 yrs ago I think it was about 10 quid a bottle back then.
As with all these organic remedies you have to apply it every couple of days and even then it's difficult to prove that it works or it doesn't.

 

I use the Grazers concentrate.

Seems to help.

 

Contains Calcium Chloride : likely to be as effective as Sodium Chloride (table salt); which is 18p for 300grammes in Lidl, just add water to taste

 

I don't think I would spray my plants with salt water.

 

I agree *, nor would I pay c£10 per bottle for a substance with unproven merit.
It remains a fact that we still need a safe,reliable, efficacious, cost-effective method of protecting our crops from molluscs.
*with exception of brassicae, which tolerate salt, effective for control of caterpillars, and sap drawing pests.

 

But it's not salt.
If it was it would damage plants, it doesn't seem to damage anything it's just that the jury is out on how effective it is.

 

I suspect the answer to that lies in the concentration of the salts in the solution. Both substances are used in food processing, the residue of the calcium is thought to be positive whereas that of sodium is thought not. I have little doubt that sufficient of either salt, if applied to the mollusc directly, would result in death, or a great reluctance to move ,( for the squeamish.) The problem is that if one could see the varmint, direct physical retribution could be effected. What we really need is an effective bait to attract and then neutralise the errant sliders, to replace the metaldehyde used successfully for more than a century.
So far, non has been offered. Ferric phosphate does not work as currently offered. Perhaps reformulation with a filler more tasty than durum flour is needed, to draw them in. I intend to blend some with oatmeal. Will report in due course.

 

I've been using the Ferric phosphate pellets and I find they do work up to a point, with Metaldehyde you could see the results the next morning, with this you dont.

But that dont mean its not working.

Yes a trip out on damp evenings is a good way to lower numbers and I usually cut them in half (slugs) or throw snails somewhere where they can do what they like without affecting anyone.
