Bean Fungicide strategy

[Ian at Bayer]

Can any of the current or ex manufacturer agronomists tell us why the labels have become so restricted please? It seems as though products have a couple of major crops on the label then the rest are on EAMUs. I suspect that the answer is to do with the costs of submitting lots of data to CRD for a label rec compared to the costs of establishing an EAMU.

Pulses and other breaks are set for a revival thanks to Ecological Focus Areas, blackgrass and a few bad years for oilseed rape.

Thanks for the prompt Brisel. Yes, what you write is fundamentally true. When products reach the end of their approval period they have to be re-registered which invariably requires submitting substantially more data which is of course very expensive, especially for a wide range of different crops. As you are aware EAMU`s are not driven by manufacturers but they are very useful and valuable for growers of minor crops.

Phosphite CTL trace elements every 14 days

Job done ;-)

Surely the bravo ban on HC beans needs to be tested in a court of law?

Can someone expand a bit on the phosphite on beans for mildew.

Its not so cheap that every 14 days will not add up to a good cost? Do all brands show results. lots out in the market now?

What timing is your first application.

I think its overrated for mildew control and nutriphite is very expensive, I've tried it quite a bit, seen no real benefits and now don't use.

Do a bit of googling around Aliette fungicide from bayer.
There are many studies showing better results than metayxl in vine disease control. In bean downy mildew potassium phosphite really dries the lesions up. Mode of action is not completely understood, although it is an organophosphate and some research has pointed towards control of pathogenic root nematode control improving crop vigour and disease resistance in the process.

First application as soon as disease seen. Cost there are Cowboys in this market as it qualifies as a nutrient not a pesticide which is a farce
Under heavy pressure I would use the alternative mode of action of metalyxl

Has anyone applied a fungicide yet? Very first flowers are out now so will probably be into them around the weekend. 2 spray programme based on alto elite

Ian has pretty much summed it up...registration is getting tougher and extra data is sometimes required which my not be held, this may be expensive and takes time so to avoid delays there are times when re-registration continues and particular crop is omitted, which may be added at a later date.
