I use the same philosophy as Meskie when it comes to crops and weed control, especially mustard. When the crop canopies over most weed issues go away. Not all, but if the ground is weed free within reason then not much gets through the canopy of mustard. I would think canola would be much, much better. I was spraying clethodim the other day on my mustard because I had the wild out issue last year on this barley stubble but there are years when mustard gets no in crop at all, the burnoff and Edge herbicide does the job till the mustard canopies over. Canola grows faster and bigger than mustard so should be less concerns. Regarding cut worms, do they chew the leaves partially or leave stems with no leaves? I have never had to deal with cut worms so don't know the evidence to look for but I thought they chewed off stems and were prone to leaving plants standing but dieing off. It definitely looks like grasshopper damage but when we had crop loss like this in around 1988 and 2003 where we sprayed grasshoppers to keep them from stripping the field bare, it was obvious. You could find 10 dead ones in a square foot after spraying and they were an 1" long when the barley was around the 4 to 5 leaf stage. Even yesterday, I don't see that many grasshoppers, and 5/8" long is the big ones and not the majority, most are 1/4". It is hard to believe its grasshoppers but chewed off leaves and the fact they are present would seem to say so. Mustard is big enough now so hoppers won't be clearing the land, but sprayed some more yesterday to keep what's there from becoming adults and laying eggs. I may have a more widespread issue with hoppers in my flax to watch. Mustard is looking nice right up to where the plants are cleaned off. Still waiting for the plants in the wetter ground around sloughs and low spots to get going. It's not insect damage in the one picture, just how mustard and flax progresses when wet. My independent opener drill can't quite seem to get even germination across its width.   |

Coverage is key when spraying, with all chemicals, but especially with liberty because it works primarily as a contact herbicide. Upping the gal/ac of water used is generally helpful for good coverage, but not necessarily. It is the chemical that is doing the work, therefore good nozzles are the most important to get uniform coverage of chemical on the plant. If the water volume is increased enough, the spray solution will begin to run off the plant, thereby reducing chemical effectiveness. (this has been proved by testing)
I'm thinking that most of the newer nozzles are of good quality, giving a good spray pattern. But if a guy wants to put down a high volume of water per acre and travel at something like 15 mph, you are going to need a fairly coarse nozzle to do that. This will not give good uniform coverage because most of the droplets will be too large. Tests have been done that show some of the droplets actually running off the plant because they are too large to adhere to the plant.
For optimum coverage you want the majority of droplets from the nozzle to be as small as possible , yet not so small that they float away in the air. This is around the 350 micron size.
As some others have mentioned, we find that weather conditions affect Liberty effectiveness as much as anything else. Hot sunny weather works the best for us.

I use Hypro guardian air 05. Alternate forward backward across the boom.

Oatking, I bet it's closer to 50 days here from start of heading to swathing. Canola is usually 4 weeks of flowers and swathing 4 weeks after last flower. But the plants are in rapid growth stages here with the longest days of the year upon us. All bets are off when we'll be combining this year!

We have barley just starting to head out, I’m quite surprised, it’s really sped up the last week since it cooled off and now that we’re got some rain it’s really picked up. It seemed to be at a standstill for quite awhile when it was so hot, looks better each day, time will tell if the heat and drought hurt the yield I suppose, but there’s a lot that can hurt the yield yet. If we could get another nice rain in 2-3 weeks we’d probably be good for the year.

Hmmm, wouldn’t you know it, it’s gone from too dry to too wet, low spots in the canola area starting to turn yellow. Overall it looks pretty good though.

We always said that the bushels made from the rain will offset the drowned out low spots. Canola is flowering around here out cereals are heading out. Wheat likely spray for FHB starting Sunday or Monday. Got a lot of our hay cut and likely be ready to roll up starting monday. |

We put our first field of barley in on May 4th and I thought it was advancing like never before, but it's still only flag with a few Beards showing here and there. Must really be givin'er there Kevlar.  |

I've got a seed corn field that won't turn not yellow. That's not good.
I give it a 50% chance of being condemned.

Must really be givin'er there Kevlar. We started our barley on May 15 and last was the 20th, pretty much all started to head out except for one quarter that we tried Connect on, it must be a little later variety, the rest is Conlon which I think must be an earlier one as we usually seem to have some of the first barley to head out in our area. |

Rains have followed the same pattern all year. That area of my farm is doing well. Other part is suffering ! The dryness sure sucks you’re energy out !

I still take too dry over too wet. May watch things wither and die but I've never had a drought take out my fences like a flood does.

We finally got a good rain the other day. Roughly 7/10. Previous rain was just enough to get cement wet and was 3-4 weeks ago. I have a field of soys just east of my yard and there’s a couple small patches where nothing is growing. Soybean seed was still there. Waiting for this shower.
