Willowherb?

[steveR]

I seem to have had a very successful year with willowherb and can see a lot of new seedlings growing on a wheat stubble, adjacent to a block of summer fallow land (now cultivated up) where it set seed, and blew...!

The stubble in question is going into a DD Spring bumblebird mix next, but I am wondering whether to spray the stuff out now it is still small, or will a Frost kill it? No herbicide option in the BB mix! If I spray, I will probably broadcast on some green cover instead.

Frost won’t kill it. Needs a decent rate of glyphosate, but is a bit easier when small but still wouldn’t go less the 2.5l/Ha+AS or Validate.

More or less sums up my thinking.... Thank you.

In tomorrow morning I think.

Awful stuff , get it whilst it’s small. Exterminate.

Done this morning, possibly a week or so late, so cranked up the dose!

I pulled up a mature plant a couple of weeks ago, and was amazed at the root structure.

I have a "crop" of BB mix that I hoped might self-set for next year, but I can see the discs rolling come March! See what levels of Willow herb overwinter as seedlings! There is a lot of ground cover, which might help, but the stuff is a survivor, as can be seen by many a building site or railway cutting.

Every single one will survive the winter without a doubt! (Unless it is help to slip from this mortal coil!)

Kyleo does a good job on it.

That is what I will use in the Spring on the areas I have overwintered willowherb.

Although, I do wonder if something like Polo would do for it?

And done, 2.5l of 490 with AS. Looked a little unhappy an hour ago, so the warm weather is helping knockdown I reckon.

Polo is 2,4D and MCPA. Do read the label before using it as it has a limited field of permitted use

In my defence... I did say "something" like Polo

All other suggestions gratefully received.

I usually roll after drilling to bruise it and then mix my pre em of roundup and liberator which seems to hold it.

In the spring the active in broadway star is good. You can consider carfentrazone ethyl if you have trouble.
