I've bought some glyphosate from my allotment society. I'd assumed I was
getting Roundup but it's something called Touchdown IQ which is
glyphosate but as sold to commercial growers. I've been advised to
dilute it 10ml in 1 gallon as per Roundup for use with my dribble bar.

It is very wasteful to use it with a dribble bar. You get a lot better
kill with a spray wand and will use much less weedkiller as a result.

but an increased risk of drift surely

It is generally not a problem provided you set the spray for moderate
sized drops you can hit things very accurately. Wait for a low wind day.
The only risk is right at the end when it takes in air and generates
very fine spray mist. That will drift much further.

If you are doing any size of allotment or garden at all a decent
sprayer with a wand is a very good investment. Just remember to clean
the thing thoroughly afterwards (or reserve it for weedkillers only).

I intend to use it just the once to get my new allotment under some
control. After that I'll do it by hand.

Thanks Martin.

I'd still get a basic wand sprayer you really won't regret having one.

Although I know a lot about weedkillers and pesticides the amount I use
per year is actually very small. Just the right amount at the right time
and in the right place - minimum inputs is the rational solution.
