    Back to peas again, but maybe not too soon in the rotation?

    Just got done applying "fun"gicide to the peas. A half section running north and south. Sprayed in crop for weeds with Odyssey in 2013 and 18. The last time there were pulses on that half was in 2013, lentils on the west mile of the half section and peas on the east side...split pretty much half and half. Before that peas were on the north quarter in 09 and the south quarter 2010. The half section has been treated the same since(rotation and chem apps...its farmed as one field). There was noticeably, maybe even remarkably, less root rot symptoms on the west side this year.

    I think there is way more at play here than blaming Odyssey, Viper, Solo and a reduced rate of Pursuit.

    I can't see Imazamox(Viper and Solo) persisting like products containing Imazethapyr(Pursuit and Odyssey). Some years dry conditions not allowing breakdown of actives and other years too wet conditions encountered after spraying might have as big a roll to play on current and subsequent crops as the herbicides themselves.

    There's other active ingredients in herbicides sprayed in previous years that affect pulses as well...then hit them on the head with one or both the Imi herbicides incrop and some adverse weather conditions and BAM...you got to wonder why the peas look "hurt"?

    The damage claims came up in the Durum thread too...durum is supposedly safe to seed the year after application but if the breakdown of the actives(Imi) never happened in the season of application because of excessive dryness.....maybe that temperamental shit durum can't handle the carry over either.

    Any thoughts?

    The blame from most in industry is put on rotation , then “wet “ weather .
    Well that is not the case .
    There is no way , ever, that one single rain event after the peas are seeded should cause root rot . This rain was June 9-10. 7/10 on the Sat night , 7.10 on the Sunday morning. No rain in May , hot and dry before and obviously since . Sprayed June 6th .
    Peas on 6 year rotation effected . Peas in 4 year rotation look perfect .. untouched.

      It’s many compounding factors

        One farm has pasture since time began we broke it last summer and seeded the whole quarter peas. Same lovely yellow. They are full of shit, I'm agreeing with Furrow on this one. Oh, a spot I didn't spray green and few wild oats. I would have been better not spraying and had dockage than pay for a useless product and have nothing.

          We have a neigbbor who is new to peas. He has a fantastic looking pea crop.

          Seems once the pathlgens that cause or contribute to root rot Aphanomycese, Fuarium, Rhizoctiniaa, Pythium are present and then the environmental stresses of weather and herbicides are added there is a potential recipe for a disaster.

          The infamous "Disease Triangle" with the addition of herbicide stress....

            I would put money on sprayer residue, it only takes a couple of grams of express to stunt a 100 acres of peas. I even know a guy that has 2 sprayers, 1 only sprays canola and peas and the other sprays cereals and express. He has the same opinion, once it has sprayed express like product it can never be cleaned out. We yellowed and stunted 500 acres of peas once with the white residue in the tank and booms. Cost us 30 bushels per acre.

              Breadwinner, just for the record, I have never used Express or Tribenuron. Unless it's in something I'm not aware of.

                i spray express every year for burn off
                have never saw a problem in peas
                for what its worth, i would not put odyssey in my sprayer
                too many guys here have also wrecked a tank full or two of invigor canola following using odyssey

                    I thought express was registered for peas if you seeded deeper than 2 inches.?????
