I used to spray Liberty at 7.5 but I was getting bad results. Then my Nutrien guy asked how many gpa I was doing and he said minimum of 10. And recommended 12.
This year one field had 5 passes that the lambsquarter looked untouched. Just a browning of outside of leaves. Can’t figure that one out. I’ll respray tomorrow.

I thought maybe cutworms but the land is cleared off right up to the edge of where I seeded and couldn't get closer due to mud. Don't think cutworms operate in mud. With the wet spring and rain we had I am having issues with crop growing around the lows spots - too wet. Have some crusted over places also. Cutworms tend to be more patchy I beleive. This is a line of bare dirt like a fire would move.
Second picture is the flax, first is mustard. I drove the flax field a few times since seeding since I lost a cleaning wheel off the drill so was out looking for it a few times. The low spots being bare I figured was just too wet, so didn't think much of it. A week later I come back to spray weeds and now the higher ground is cleared off. The mustard I hadn't driven that area since seeding, was out the day before with blade fixing ruts about 500 yards from this area but had no reason to drive over the ridge.

My agronomist wants me to spray liberty at 20 gpa, coverage is key. I sprayed it at 15 gpa. Can't get anything done spraying 20, 15 worked good.

If the crop and weeds aren’t very big 15 gallons/acre would be lots

Any post application here 15 gpa is normal. Roundup post used to be 10 gpa max but even that is 15 gpa, 12.5 gpa minimum.

Had cutworms in canola once where they had a front like that. They were racing each other for the next green plant. |

Looks more like cut worms to me also but don’t have much experience with hoppers.

Got a small field with half inch hoppers. There was a flock of gulls feasting on the buggers this morning. Might have to spray if they survive this wet spell.   |

Haven't had to spray Liberty for a few years but always did at least 8, best results 10+ on a warm day. Any post application here 15 gpa is normal. Roundup post used to be 10 gpa max but even that is 15 gpa, 12.5 gpa minimum. Interesting, I use from 3.5 to 5.5 gal/ac when applying Roundup pre, post, whenever. |

I don't know if it's to do with the humidity or what. Everyone says coverage is key in post applications.

Glyphosate has always worked best at 5 gallons for us. No matter what we did with Liberty it was never anything better than weed suppression. Always looked like it hammered the weeds but they would just come back.

Never had a problem with liberty at 10gpa and is all I have ever sprayed at. Should have two hour of sun left when you are done too, late or night spraying of liberty does seem to work well with it.

We actually find liberty works better at 10pm than 10am. Sprayed it in the dark lots of times finishing up a field and has always worked. In all the years we have used liberty I can’t remember it not working for us except a couple times we started too early in the morning. You could see where we started the tank to where we ended for weed control. I always thought liberty was to suppress the weeds long enough till the canola cabbages over and covers the ground. That keeps any new weeds from growing. We use enough roundup that it’s nice to use a different chemical on our canola. And haven’t found a canola to out yield an invigour for us yet. |

From the start of heading out on wheat barley or oats to swathing and or harvest , what do you figure is the typical time frame on average? I use 35 days to swathing . So about a month. That would put us in the red river valley around July 25 ! That is crazy early! Wondered what your assessment is on your crops ? |
