Winter Beans Pre-Em

Zippy768 · Oct 15, 2020

So Blackgrass, Cleavers and Charlock are the main issues.

For Blackgrass, Kerb is the only effective option. And needs to be pre-em? (Blackgrass isnt awful)

How well would a Nirvana work on Cleavers?

Could I get away with dropping the rate of Nirvana and boosting with some straight Pend and still keep on top of the Charlock?
Will anything take out Charlock later on?

Presumably I could do Kerb and clomazone which would leave me with the charlock issue.

In osr in the past on these fields I didnt bother trying to sort the charlock. Would leaving charlock in beans be a massive problem?

Few day workers with decent gloves on.

Blackgrass- either Kerb pre em or Crawler post em. Kerb has some broad leafed activity on weeds like chickweed that Crawler doesn’t.
Cleavers - clomazone pre em only
Charlock - harder to call this one but ignore it at your peril. Nirvana is expensive but would do a better job than straight PDM. Post em you have bentazone but that is not cheap and unreliable.

Kitchen sink pre em(with glyphosate if left late) to avoid post em expense & likely failure. As stated, charlock destroys yield in winter beans.

Fudge. Charlock more serious than i thought then.
A kerb, Nirvana and clomazone mix is big money.

What's the advantage of kerb/clomazone mix over pdm/clomazone - apart from the blackgrass aspect

PDM has a reasonable weed spectrum. Much wider than Kerb

If only Blackgrass and cleavers were your main problems, amg and speedwell about as well.
Would u go just kerb and clomazone. I.e drop the pdm altogether?

Yes, I would. Don't forget the charlock though! Bentazone is not reliable and needs to be on when the weeds are small in warm weather, which will have you clenching your butt cheeks in a cold March...

Haha only half of the bean ground suffers from charlock and only half suffers from bg. Unfortunately a quarter suffers from charlock and bg

. Gonna be a hefty mix

with spring beans if they are bad i use bentazone
after a frost can be very effective

if they are low level the pollen beetle usually stops them seeding

Defy very good on charlock and vol OSR.

2 litress each of Kerb, PDM, Defy here.

I wouldn’t omit the pdm myself unless I was using defy. You need kerb, and clomazone and it’s just a choice what the other partner is. Basagran can be quite good on the right day, don’t let the weeds get too big.....

Zippy768 · Oct 15, 2020

Is Defy ok on beans.
Presumably the later I drill, lessens the weed pressure?
Sprayed off and ready, but seed not arriving till Monday......just as the weather changes

Brisel · Oct 15, 2020

I’ve never used it on beans. It has an EAMU for cleavers and others.

It’s very early yet as far south as you imo. I’d be leaving it a week up here.
