A lawn has plenty of space for weeds and offers an ideal breeding ground for many species. Once these have spread, removal is usually difficult. That is why there is Banvel Quattro, previously marketed as Banvel M. Before you decide on this path, you should find out in detail where and how it works and how to use and dose it.
Table of Contents
Banvel Quattro is a weed killer (herbicide) specially developed for use on lawns and meadows. The product is also permitted for non-professional use by law, provided that various specifications/conditions are observed. This includes, among other things, the application and the dosage. It is available for pouring and for spraying.
ingredients and effects
Two main substances make the Banvel Quattro weed killer an effective herbicide: dicamba and MCPA (herbicidal substance). These ensure that a kind of artificially induced growth acceleration of the weeds takes place. The plants themselves do not register this, so there is no automatic/natural nutrient uptake as is normally the case. As a result, there is a lack of nutrients and the weeds die down to the roots. The effect refers only to the two-germinated plants. The mononucleated lawn/grass is spared. Since not all dicotyledonous plants/weeds react equally well to the growth effect, the length of time it takes for the effect to set in or for destruction to take place does not always take place.
There are thousands of weed species and not all have the same structure, which is why not every weed killer can work. Neither does Banvel Quattro, which can be successfully used purely for the elimination of dicot weeds. However, there are also strains in this category that respond less well to the formerly named Banvel M. The following list provides an overview of the various weeds and the expected effectiveness:
Very effective and fast-acting, for example against:
- Ackerdistel (Cirsium arvense)
- Wild radish (Raphanus raphanistrum)
- Wild mustard (Sinapis arvensis)
- Binsen (Juncus)
- Nettles (Urtica)
- Broad and buckhorn plantain (Plantago)
- Fingerkräuter (Potentilla)
- Speedwell (Veronica)
- Gooseberry (Bellis perennis)
- Goosefoot (Chenopodium)
- Garden cuckoo flower (Cardamine hirsuta)
- Gundermann (Glechoma hederacea)
- Hahnenfuß (Ranunculus)
- Clover such as sweet clover, white clover, trefoil or wood sorrel (Trifolium)
- Löwenzahn (Taraxacum sect. Ruderalia)
- Schafgarbe (Achillea millefolium)
- Vogelmiere (Stellaria media)
- Knotweed (Persicaria)
- Wicken (Vicia)
- Meadow Sorrel (Rumex acetosa)
Less effective for:
- ground elder (Aegopodium podagraria)
- Horsetails (Equisetum)
- Bärenklau (Heracleum)
- Meadow chervil (Anthriscus sylvestris)
Little to no effect
Banvel Quattro is added to the water in liquid form. This can be normal irrigation water or it can be filled into a spray pump such as that offered for spraying plants. In order to achieve the maximum possible effect and to use it optimally, you should also adhere to the following application specifications:
- Temperature between 15 degrees Celsius and 25 degrees Celsius (the warmer, the faster effectiveness)
- Application months between April and August
- Five days after the lawn cut
- Lawn/grass must be dry
- Ideal: no rain for at least six hours after application
- Do not use if there is a risk of night frost
- Next lawn clipping no earlier than five days after application
- do not use on new seedlings in the first year
- One application per crop per year
- Be sure to use the correct dosage
- Thoroughly clean the spray/pour container with washing-up liquid after use
- Do not allow leftovers to run into the sewage system or bodies of water (risk of a fine of up to 50,000 euros)
Before Banvel M or Quattro is used and dosed, it must be shaken vigorously so that any substances that have settled on the floor and/or walls are loosened and all ingredients are optimally mixed. The following dosage must not be exceeded because the product falls under the Plant Protection Products Act. An enclosed measuring cup facilitates exact dosing.
- Basic rule: one milliliter Banvel Quattro per square meter
- Spray pump: Dissolve 50 milliliters in five liters of water and spread over 50 square meters
- Watering can: add ten milliliters to ten liters of water and distribute over ten square meters
After applying Banvel Quattro, the lawn and meadow clippings should not be used for feeding for the rest of the year.
This herbicide is a chemical agent that can cause soil pollution. If it rains before the end of five days after use, there is a risk that it will get into the groundwater, which is why the legislator insists on strict compliance with the dosage specifications. In principle, it should only be used if chemical-free and environmentally friendly products have not brought the desired success or if overgrowth can be controlled quickly and reliably, so that there is no time to experiment with possible home remedies, which is usually longer need until an effect becomes visible.
storage and disposal
In addition to the application and dosage of Banvel Quattro, storage and disposal are worth mentioning. The product should always be kept in its original packaging so that there is no risk of confusion with a less harmless product. The place of storage should be frost-free, dry and cool. Empty packaging should be disposed of via the recyclables collection, while packages with product residues should be treated as household chemicals and accordingly handed over to the appropriate collection points.
