Yellow rust 9Never grown it. Do I look up the disease resistance for you?
That would appear to be a suspect move, the issues arose Tuesday/Wednesday and Corteva released their statement WednesdayYellow rust 9
Brown rust 5
Septoria 6, 5.8
Last time it appeared on recommended list 2 years ago.
What disappoints me is my Elatus Era which we had in stock was taken away on Wednesday and replaced with Univoq on Thursday. At the time I wasn’t aware of sprayer issues and thought it must have been swapped for sound agronomic reasons. Maybe it was. But I’m feeling a bit angry about it. I am just doing a bit of asking on here before completely losing my rag, or not.
Corteva are saying that they have had no trouble with their products in France or here when they were used for T1 so are trying to find the problem! It’s just a case of wait and see but I will be keeping any invoices for any rubber products on my sprayer from now on until they have sorted out the problem.Sprayed Wednesday ant Thursday
Washed out at night
Had problems with o ring in the return system check valve which may have not cleaned out properly
Not as yet had problems with dcv s
now finished using univoq straight 100 litres per ha Househam spirit with dcv drip stops
If we use it again next year I will mix spray up in advance in a can and put rubber rings and diaphrams in soak or a week or two
Even if corteva say they have changed the formulation
did any one trial it last year or has the formulation changed
in the past there have been problems with
Folicur blocking jets
sportak rubber degradation
betenal rubber degradation
Any others ???
