Product information "Roundup - Rapid concentrate - 900ml - for 400m2"
- Concentrate
- Effect after 3 hours
- Herbicide
- Acts also against moss
A total weed and moss control agent based on pelargonic acid, an active ingredient found in nature. The formula of this herbicide is highly concentrated and works by contact. Roundup rapid quickly eliminates weeds and mosses by dehydration. After application to the plant, the plant cell wall will be affected, causing the plant cells to deflate. This leads to complete desiccation of the plant tissue. Treat on weeds (annual and perennial) and mosses on unpaved permanently unplanted areas. Visible results can be expected after about three hours. Quickly biodegradable in the soil. Sowing and planting possible after 1 day.
When to apply Roundup?
- On a calm, dry day
- Temperature between 12°C and 25°C
- Do not apply if there is a lot of wind
- Do not apply if it rains
- Do not apply if it is very cold
- Do not apply if it is very hot
Make sure you apply Roundup to the leaves. It is important that you spray the entire leaf, but make sure the liquid does not run off the leaf. The best time to apply Roundup is when the leaves are green and still growing, usually in spring and summer.

- Weeds: 45ml/1 L water /20m²
