This Resolva product is a systematic, non-selective, and non-residual weed killer. It seeps into any foliage it touches and travels down into the root system where it destroys the growth enzymes. As a result, it kills the weed and prevents future growth which is what helps makes it so effective. The weed killer comes as a concentrate which you dilute down and can then spray/water onto your weeds. Just a little note here, this stuff can hang around in your sprayer/watering can even after rinsing them out, so never use the same watering can that you use for your plants!

However, some online reviewers state that they had to use more than the recommended concentration of solution to water to obtain any results.

Simply wait a little longer and see what happens.Since 1 January 2021 decisions in the EU and UK may mean the final expiry dates for a single MAPP number are different in Northern Ireland (NI) which follows EU rules, and Great Britain (GB) which is operating an independent PPP regime. When the only difference is the expiry date, the same MAPP number is retained in both regimes. This will result in more than one retrieved row for the same MAPP number; each with different expiry dates and 'extent of authorisation'. The latter entry will show whether the specific expiry date applies to GB or NI. Allow about seven days for the methodical action to get deep into the roots if applied to areas with dense covers, such as perennial weeds, before digging or cultivating. Application can be done by sprayer or a watering can that’s fitted with a very fine hose. We always recommend using a sprayer if possible as the diluted weed killer goes a lot further.

It does take a while to dry – up to 48 hours.Flazasulfuron works on weeds when they first start growing, as well as when they are in their ‘adolescent’ stage. It’s absorbed by the roots and then works its way through the rest of the plant. Some people also choose to use homemade natural weed killers, using a solution of white vinegar, salt and liquid dish soap. Alternatively, residual weed killers will stop all plants from germinating, and non-selective weed killers will kill everything they encounter .

It’s a naturally occurring acid in geraniums. This acid is generally considered effective at controlling the growth of smaller broadleaf weeds (under 15 cm tall). One thing to note about this weed killer is that it doesn’t work especially fast. To kill the roots, it needs around 3-4 weeks. While the weeds do start to wilt within a few hours, it takes 7 days before I actually felt the weed killer was working! Despite the slower results, it does work as well as others on the market, and it’s very easy to use.
