My canola will only do 40. Killing it with buctril m

[Klause]

Bromoxynil doesn't do much on brassicas.


We sprayed our flax Thursday night then curtail m. Then got a shower. Checked in thr am before we went to farm progress weeds all turned over and flax still straight as an arrow heehehehe

Tweety, it went into decent moisture but have been losing ground in that department steady. "Need a soaking rain"...repeat,skip,repeat,skip,repeat...

And the rest of the MCPA Ester story.
Label recommended flax rates. How much MCPA Ester:

BucM 280g/l @ .4 l/ac = 112g/ac

MCPA Ester 600g/l @ .28 l/ac = 168g/ac

CurtM 280g/l @ .61 l/ac = 170g/ac
@ .81 l/ac = 229g/ac

I was after hemp nettle and the MCPA label says we need .42 to .61 l/ac or 252g/ac to 366g/ac for suppression. How safe is that for the flax? BuctM at label rates in ten gallons/ac water flattened our flax. I was going to add a couple of ounces of MCPA Ester for extra kick, but didn't.

Is it surprising BucM isn't very effective?

Regarding rain, I decided to grow a drought beard, not shaving until I get an inch of rain in one shot. ;-)

I just can't figure out why flax gets dinged so hard sometimes and other times not. Doesn't coincide with growing conditions moisture even using high water volumes - whatever. Maybe it just comes down to humidity, i just don't know.

Farmaholic, to get the hemp nettle better, MCPA K is supposed to be better. I dunno about for flax. But I found a booklet from the 80's of my dad's which confirmed this. It called for a mix of Pardner with MCPA K for hemp nettle control.

[cottonpicken]

I agree tweety.

Actually klause my experience is buctril works better than curtail on canola volunteers. My curtail flattened the flax also. Gets back up in a day or two. Most important is spray earlier than later I find later flax spraying to do damage.

[farmaholic]

Thanks freewheat. Don't see much MCPA K or NA in retailer chem sheds.

yea , curtail only has mcpa and lontrel , pisspoor unless you need lontrel for perennials . would be weak on volunteer canola . I think it is the humidity that burns flax worse . I sprayed flax early one morning while still wet , really gave it shit

[Guest]

we held back one jug buctril , added 3 jugs ester 600 on a quarter , we will see in a few days , doesn't look bad yet

[Hopperbin]

Been 3 days since spraying the first 6 quarters. 2 curtail 4 buctril. Both have about the same bending over of flax plants in various degrees throughout the fields. Big difference in how the weeds are dieing. Similar wilting buctril more I think. Buctril fields weeds are turning white curtail fields only show wilting. Time will tell who wins. But sure looks like buctril has the lead.
