Glyphosate weed killers kill through a systemic progress. This means that the liquid enters the leaves of the plant and works its way down through the plant’s entire internal system, all the way down to the roots. The glyphosate is the poison, and it kills every part of the plant from the inside, from the leaves down to the tips of the root. The bottle of weed killer automatically dispenses out pre-measured amounts of the concentrated product. Although some thought is still required whilst making up the diluted formula, it’s easier than a classic free-pour dispenser.

The output can be adjusted, producing either a spray or a fine jet.

Gallop eliminates most annual and deep-rooted perennial weeds and grasses, which is good news. Mare’s tail is frequently killed as well.

Some weed killers don’t start working until several weeks or even months after they’ve been applied.

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. Like most weed killers I’ve tested, this product does contain glyphosate which isn’t wildlife friendly.

The 1 litre super concentrate formula we reviewed treats a maximum area of 90m2 so gives you plenty of coverage even on fairly large areas. However, some online reviewers state that they had to use more than the recommended concentration of solution to water to obtain any results.
