Why buy it now? The weather is already too cold for it to have a full

Many of the more stubborn weeds inc. Japanese Knotweed are considered to
be more likely to be affected by poison if sprayed as they are winding
down for the year as they take the stuff into the roots.

There is the alternative that you never hear of now which is to mix
the concentrate with parafin. Penetrates a lot better.

I've only heard that in relation to woody stump killers which iirc
are not glyphosate.

Glyphosate weedkillers are applied to growing green leaf and
translocated from leaves to roots; it's hard to see how adding oil would
increase leaf absorption.

It won't AFAIK - washing-up liquid often helps with glossy/waxy-leaved
plants such as ivy, and ISTR it being suggested for ground elder and
Japanese knotweed
