Edge on liberty link canola

Anyone using this what rates are you using on the edge if cut what restrictions as far as recropping next year are you following

Isnt edge weak on barley the same as liberty? How does the $$$ compare vs liberty?
Is this to replace the liberty or just enhance control?

[macdon02]

just using it to enhance control using 17 lbs in fall and 12 lbs in spring. Cost is 12/ac on spring rate, not looking for complete control just set the weeds back for 1-2 weeks so liberty will work better. Tired of spraying second time, am doing this because I seed canola first then oats, only have 400 acres wheat out of 6500 ac. I am hoping to seed w wheat this fall on to the edge ground or oats next year, but both options are making my guts turn. Think I might be stuck with barley that doesn't pencil(i hate chasing the malt carrot) or I guess i could try peas? Any thoughts appreciated.

Never put peas after canola. The best is wheat. Canola does not host mycorrhiza fungi and peas need this fungi .The lack of this fungi has least impact on wheat.As much as 30% yield loss can be achived growing peas after canola. If you're needing a better weed kill with liberty find yourself a good foliar nutrient one that has everything in it. It will help the plant intake the chemical. It masks the chemical. As well foliar applied is worth 10x more then ground . So if your lacking any nitrient the foliar will help out there as well. Just make sure it's compatable. One pound foliar applied is the same as 10 pounds soil applied. As far as the malt carrot reduce your spring applied N rates.I would try no more then 80 lbs/N. Then foliar apply N later on with herbicide if needed. Over loading the ground with N is wasteful as well keeps your crops green longer. As much as 50% of N applied in spring will never make it into your plants ( theory behind the greenseeker and many other documents). Reducing N will let the plant mature more naturally and a small amount of N applied foliar will not increase protiens just help in plants health and devolpment.

There could be a reason for that, foliar is closer to 5:1 providing it's in a form that doesn't burn the leaf and is plant available, there's alot of snake oil out there. Providing you have good organic matter levels and good moisture through the season and you're not making edge or any other form of trifluralin, or triallate a habit you shouldn't have alot of problem, maybe some tiller loss on erroded hill tops. But a guy has to ask if all the hassel, cost and yield loss, rotation restrictions is outweighing the couple of bushel difference you'll see by going with an RR canola. The yield gap has closed alot in the last couple of years...and no I don't work for a seed co.

Thanks guys sorry for sounding cynical but you know.lol The reason I switched to invigor is because rr volunteers are starting to give grief. All IP acres and the only way I get liberty to work is on later seeded canola just doesn't cut it on early seeded crop. Not warm enough when first app goes on and not enough up when burn off is done. Not sure if you follow the problem, I don't seed alot of wheat or barley 400 ac of cps on 6300 this year no barley. My rotation is half oats half canola, with a little w wheat when I get it in. RR worked great in this rot. cleaned out w.oats and set things up nice for oats. But last year sprayed some ll fields 3 times, centurion and 2 shots liberty(not doing it again). Just looking for new angle on problem, and oddly enough it isn't the grasses causing the biggest problems, been using prepass every spring and now switching to fall app on oats dessicate religiously, frontline in crop, trying to throw everything at the land to get it clean. Lambs quarters, hemp nettle, cleavers, odd ball crap.. yellow whitlow grass, pygmy weed, as I get one problem cleaned up new ones show I guess this is to be expected just thought maybe switching away from group 2 in cereals to more preemerge activity would get better results. thx

Oats will be hit the hardest by edge. I don't think you'll ever get away from RR volounteers even if you never grow it ever again, but your prepass should keep those away until you need to spray. Switching from frontline into 3/4 rate prestige or that new stuff, Stellar I think, will notch up your control on those harder to kill weeds, Infinity might work too but I think it's a little overated for the price and it seems to be a little hit or miss. I would be curious to see what Arysta says about fall applied everest on your ww, it might open up recroping restrictions with that.
