Sprayer tank cleaning between crops

[wellingtonfarmer]

How many dishwasher tabs do you use? Pendamethlin is my biggest cleaning problem

Do you need to worry too much about Pdm? Surely as you use as such high dosage rates once you have emptied rinsed and filled sprayer back up any residual pdm is going to be very extremely diluted it won’t affect following crop?

The best thing to do with PDM is use the encapsulated form of it although I admit there is still some staining with some of these.

But it doesn’t seem to work as well?

Went from atlantis/pacifica on wheat to herb on beans.
Gave it a triple rinse with Al clear in the second rinse.
Probably overkill. Took me way over an hour

Rarely tend to use any products here, just rinse, rinse, rinse with copious amounts of water. The recirculating lines are the one thing to be aware of most I find.

I'd be interested to know what rates people use these products at when cleaning tanks.

Just looked up Tank & Equipment Cleaner and see it says 500g per 500l water. Instructions say half fill tank, add T&EC then top up. At that rate a 4000l sprayer would need 8 pots. Surely it doesn't need a full tank full to clean the sprayer?

If you've been spraying su herbicides on cereals, then want to spray sugar beet. I use a tank cleaner such as All clear / tank cleaner
Usually with the rinsings I have a stubble field which I would opt to spray on.
If not, does All clear / tank cleaner have any effect spraying back onto original crop, in this case cereals ?

When we grew beet here back in the Golden Years, I bought a 600l mounted sprayer purely for spraying the beet, didn't cost much and saved hours cleaning out after cereals etc. At 80l/ha it was a win-win as it allowed a single set of nozzles on each of the sprayers.

Trouble is, the Sprayer testing regime may make it impractical?

I think many potato growers run two separate sprayers, one potatoes and one for cereals. Avoidance of a mistake can save an enormous amount.

Thats what I do, the tractor that plants and harvests the potatoes can lie on a sprayer in between to do all the arable, and the one that does the destoning gets the pleasure of the other sprayer.

I think I was once told 3 rinses is best. My 4000 litre tank has a a 450l was tank so I like to do 3x 150l rinse.

how would you like 25000 ltr of wZter and 25 ltr of tank cleaner all clear through , before going into veg to eliminate any trace

Having heard of the tale of a neighbour who was not fully aware of the dangers of SU herbicides, it seemed a sensible option...


Also saw the effect of SU's on a following stubble turnip crop here...

Use it with sil-wet.

Interesting this time , had to take out some tulips in barley , had su , baled one filed chopped other and both Had sturnips in them , one was good ,after baled other was held back , chopped ,so wonder if any residue in straw also ,as another field what was chopped and no su was good too ,
using hiatus if need be now ,

'twas a long time ago, but I moved to old fashioned chemistry for cereals when I was putting in ST, then beet. Tried a chisel plough cultivation as an experiment, with a field where I had used SU. ST came where the soil was inverted a bit, but the crop was not good. Plough was OK, but the cost!!

That's odd. I've had rape failure after spring barley treated with SU in one drill miss the length of the field, rest of the field was fine. I struggled to explain that, I guessed that in the miss the SU hit the soil where it wasn't broken down, unlike the rest of the field where the barley plants broke it down? Was it barley in your example? If it was could be allelopathic effect of chopped straw, combined with the SU residue caused a poor crop but the effect of either on their own was not enough to notice a difference?

Quite happy I don’t do veg now. That could take a while

Somebody's been floating a SP Househam 30m in Farmers Guide for months, with the strapline "Cheap enough to keep for Beet spraying"

It's the staining that bothers me most.seems to stick to the steel tank much more than the plastic one on the previous sprayer.

I use one sprayer for everything. Bateman Hi Lo. The problem we hard when we used a separate sprayer for beet was sediment built up in the lines no matter how well you flushed it. It would dry out over winter then flake off during the next season causing bother with the nozzles.
So we just use the Bateman for everything. I normally washout the 2000 litre tank with 2 x 100 litres of plain water. If I’ve used an SU I’ll do that then go back to yard to refill wash tank with another 200 litres, add all clear for the first 100 litre wash leaving it in the lines and system for half an hour or longer, spray out then then wash out again with 100 litres clean water. So it’s only SUs that require a trip back to yard to refill wash tank and pickup the tub of all clear. Make sure to flush the filter during the wash to clear out any partially dissolved particles. Sometimes I’ll take the end nozzles off the lines and blast them out.

So, when using tank cleaner / All clear, do you spray it out back onto crop or onto a stubble field to dispose of rinsings ?

 

[DrWazzock]

I spray it back onto the crop. But not on a weedy part in case it neutralises the chem I’ve applied. I’ve never a weedy patch where I have sprayed it onto the crop and haven’t seen crop damage. On a field scale, a litre of all clear sprayed out on a hundred metres isn’t much to worry about I think, though others might know different.

 

[DrWazzock]

I think it looks better on the records spraying out onto the crop.
Backing up to a bald bit and letting the All Clear go on that would never do would it?
