What's your preferred trace element mix?

[FarmerBruce]

We put Mn on our cereal crops with most sprayer passes, particularly barley on our lightest soils. Once symptoms appear the leaf loss can be quite horrible.

As is happening here now!!!

Same here. High pH soil, since I've increased the amounts of mg I use bushel weights have improved and I feel yields have aswell.

I'll use 5kgs of epso top 3 times.

MagphosK.

Not sure this contains any manganese but I agree it is a Rolls Royce product that would be ideal on smaller areas than aren't enough to justify an IBC. Used it a lot and would recommend.

Liquid. Life's to short to be titsing about with bags of powder.

I agree.

What is your soil index for Magnesium? I appreciate the difference between theoretical soil supply and plant availability.

 

[Farmer Roy]

Cotton Mix 7777, about $3 / l in a 1000 l shuttle

7% Iron, 7% Zinc, 7% Calcium, 7% N, foliar at 4l / ha

based on doing foliar trials & responses

Some ones but mainly 2s

I prefer not to use them. Except for Yara SupaMan on peas, not that we have ever had Marsh Spot problems in the past, but it would be expensive mistake if we ever did.
Edit: Oh and I used to use Boron in rape back in the day.

I would like to apply more foliar Sulphur, not just as a nutrient but also for its fungicidal activity on sugar beet and also cereals and OSR. Anybody doing this and what products do you use and timing please?

I'd guess you'll need something like thiovit powder.
As an experiment I did try using thiovit in the autumn for mildew control in barley but the year I did it there wasn't any mildew about anyway.

As a side note I do think the lack of sulphur in the atmosphere is increasing the disease burden. I've noticed how quickly machinery goes green and roofs get covered in moss too, which is something that didn't happen 20 years ago.

Used to do thiovit and opus

Apparently the French are doing lots of research into sulphur as fungicide because if a push by there government to use less Chems and the loss of multisites.

Not sure what rate would do a job on fungus but we IIRC we would sometimes be 5kg of sulphur and 3 of manganese, had to spray it out even if it was pushing with rain!

I've done that mix before N and S blends became the norm when sulphur was only just starting to become deficient in crops.
That mix at TO ish timing and another 5kgs at flag leaf to ear emergence would really make a crop of wheat go lovely and dark!

 

[Secret Agronomist]

Tempted to try it again as mildew control is getting expensive using cyflamid, not sure what rate I would need for fungicidal activity.

Cyflamid is good stuff. Used to use it in combination with an azole where I had big thick crops.

Might aswell use proline, especially in wheat and then you have a bit of action against eyespot aswell.

Till now we've been largely epoxy based, tracker at t1 and Adexar at t2. Relying on the boscalid for the eyespot as more likely R strain up here , or is it w strain, the opposite way round from you guys though! Maybe we worry too much about eyespot though, but been bitten badly in the past. Suggestion for this season looking like, entargo and revystar at t1 the more revy at t2 for high yield sites, so not me then!
