Zinc seed treatment to replace Deter ??

[Syed Shah]

Just visited a farm where grower has been encouraged to use Zinc seed dressing to control Aphid (BYDV) in cereals. Totally disagree with that. Any comments?? .

 

[AndrewM]

seems more likely that they are trying to replace the £ margin on deter than its effectiveness against aphids. can't see zinc doing much

 

[MNBVCXZ]

Possibly......
BYDV = rooting issues!
Zinc = increases rooting?
Can’t see it having a great enough effect.

There's various papers about it but nothing overly relevant to uk cereal production!

Are we talking controlling the insect or the virus? If zinc controls viruses, the medical profession ought to be told.

 

[Syed Shah]

Virus and it’s impact on yield

 

[Brisel]

Hmm. I smell bullsh*t. Who is doing the encouraging? Sales rep agronomist? What does this cost/ha?

An attempt at mitigating the symptoms of the virus is dodgy with little science behind this to justify it. Better to use other methods like delaying drilling etc.

I'd have gone sulphur and silica

Totally agree. I have asked for the data.

Was BYDY that bad before the days of Deter ?

aphid resistance to the foliage applied insecticides was significantly lower.

I see the new barley “BYDV tolerant” varieties still recommend full pyrethroid programme !

 

[Syed Shah]

It’s all about risk management strategy, buy tolerant variety ( not going to be cheap anyway ) , then spray with pyrethroids to control aphid , use trace elements to improve crop health , biostimulants to improve crop tolerance , please buy all products from us and if yields poor then it is down to weather or pests resistance to existing chemistry. Sorry it’s not my fault

The first thing my chiropodist wife does with verhuca patients is put them on zinc suppliments. Works best on children where they often disappear without any other treatments.

Of course, as with zinc for BYDV, there is no scientific evidence to back this up, but in practice, it works.

 

[Syed Shah]

How much zinc do you apply , how often and on which cereals? I am in process of putting together all the information so I can share with AHDB for their comments. I have been reviewing several agronomists gatekeeper / muddy boots recommendations and I am finding it hard to convince myself recommending on other farms. It will be nice to know what steps / research methods were used to be ascertain that it (Zn) works. If you have any yields maps etc lease can you share ?

Zinc coating controls rust but thats on steel work though!!!

 

[Hindsight]

Yes, but what about virus in steel work? What impact does Zinc have on that?

 

[JCfarmer]

Yes, but what about virus in steel work? What impact does Zinc have on that?

Ah well now thats another story. The virus in steel work known as the 'BENDS' which is the most common and often passed on by bad tractor driving or nutty cattle, I have proven beyond doubt zinc is totally useless.

Makes children disappear eh? Sounds useful stuff

Applied zinc to a field this spring that had evidence of BYDV patches ......... it really did seem to help, patches picked up no end over the following few weeks, yield was no worse that surrounding filed that had no evidence of patches
