It is exclusively for non-agricultural land, but can it be used for fields?

The Agricultural Chemicals Control Law stipulates that fields, flower beds, vegetable gardens, planters, and other places managed by people are “agricultural land,” and other places are “non-agricultural land.” To use it on agricultural land, it must be registered as a pesticide (regardless of the content of the ingredients of the product). Since this product is not registered as a pesticide, it is “only for non-agricultural land”. Therefore, please refrain from using it in fields, vegetable gardens, flower beds, etc. There is no problem with safety.

I have a pet, is it okay (safe)?

The main component that kills moss is grapefruit seed extract (GSE). As the name implies, it is extracted from grapefruit seeds and not chemically synthesized. Grapefruit seed extract is recognized as a food additive by the Ministry of Health, Labor and Welfare and is widely used in various foods. As a matter of course, the safety to humans and animals is strictly examined, so it is safe to use it in a familiar place and even if it gets in your mouth.
addition, it does not contain components such as inverted soap and copper like general moss removers. No chemical synthesis preservatives are added for the purpose of maintaining quality. A safe and secure moss remover for pets as well as humans.

Can it be safely used for Nostoc commune for the lawn?

Basically, it’s okay, but if the tip of the leaf is cut with a lawn mower, the color may change from that part. Also, please refrain from using this product because such lawns may connect to agricultural land.

Can it be used for grave stones in the cemetery?

It can be used without problems for general tombstones such as granite (black granite, white granite, etc.). However, it may cause stains when used on marble. Just in case, spray a small amount on an inconspicuous place and check that there is no change before using.

Is there an expiration date?

There is no expiration date for the undiluted solution of moss cleaning spray 500ml diluted solution and moss cleaning concentrate. GSE (Grapefruit Seed Extraction), the main component of moss cleaning, has excellent antibacterial properties, so it will not deteriorate in the product and lose its effect. However, please use it as soon as possible after opening. Do not store the diluent for a long time and use it up. Please keep away from direct sunlight.

Does it work on Nostoc commune?

 Yes, it does.  The spray type is effective, but please use 5-10 times dilution of concentrated liquid type. You can get better results.

Again, it has formed loose clumps. Is this working?

Even if the Nostoc commune colour changes (from green to light brown) after using the moss remover, it will turn to loose clumps when it rains. After the discoloration, the Nostoc commune becomes unable to photosynthesize, and it gradually gets smaller and smaller and dies. It takes a long time to get rid of it, so please remove them with a broom if you are concerned about appearance.

Does it work on liverwort?

Yes, it does. But using Liverwort spray is faster to get rid of and more effective. Please use Liverwort spray.

Is it effective forBryum argenteum and Bra hymenium exile

Yes, it is effective. It turns brown and dies (suppresses reproduction). It does not disappear, so if you are concerned about appearance, please remove it.

Is it safe to use it on moss on trees?

 Trees will not die with the use of moss cleaning. However, the moss cleaner is a product for non-crop fields only, and it is prohibited to use under the Pesticide Control Act

Is it OK to use on the exterior walls of my house?

Yes, it’s OK. It won’t damage the substrate or discolour. If you are concerned about it, try it out before using it. Please leave it for a while and do not rub it after applying. If the moss has small rhizoids, they will fall off naturally when it dies. In rare cases, there may be a rain stain on the SURFACE where the moss was. Please note that it does not work on the rain stain.
