Sprayer problem.

[Chae1]

Went to spray off some barley for a neighbour snapper glyphosate, chaperone wetter. Used that mix for him several times already without problems.

Yesterday started, most of nozzles blocked. Went home took them off unblocked them all and went to start again. Same again, most blocked within minutes.

So went home again, dropped contents of tank into Ibcs. Couldn't see anything floating about in tank contents. Removed all filters, Completely clean.

Any ideas what problem could be? It looks like a pink stringy material in nozzles. It's obviously bypassing filters. I know glyphosate is a good tank cleaner. But I have been spraying just glyphosate since early August.

Here goes a nozzle. They weren't all this bad.

Sparrows nest in the spray lines? (more likely slugs than sparrows but it is going to be grim imo)

Pod Stick?

How I hate days like that.
Wild guess - calcium or magnesium precipitating out of the water?
Mains water / borehole / roof water?
'Hard' water?
Is Chaperone an acidifier / water conditioner?

Had the same with half a dozen nozzles. Snapper and chaperone as well. Thought it was something I’d just done. Could the pink stringy be manganese?

I get something similar if I store mixed glyphosate+conditioner, but filters sucking it back into the tank usually sorts it out.
Were you in a hurry and forgot to flush your booms last time you used it?

How long has there been glyphosate in the system for? Diluted gly will become scummy and stringy if left in a warm place.

Has the adjuvant lifted off some residue in the lines or tank?

My tank hygiene has not been as good as normal. I would normally rinse out with clean water every time I'm finished. Been a bit smash and grab with harvest. Been jumping off sprayer onto a baler. So rinsing out been neglected.

Some Tank & Equipment Cleaner from Frontier will get it out.

Other suppliers are available

True, but DeSangosse products seem to be exclusive to Frontier. Any other good cleaners apart from All Clear Extra, liquid fertiliser, glyphosate and the above?

Caustic soda, used at the appropriate concentration. Hot water (i.e from steam cleaner) may help.

I wouldn't leave a sprayer sat with spray in it for any length of time if you can help it.

I always (try to remember to) purge my booms with clean water if I’m leaving the sprayer over night no matter what. Not so worried about the tank with the likes of glyphosate.

Leave out the adjuvant when using the glyphosate methinks.
Very hard water here and I’ve never seen generic glyphosate not to work.

Thought I'd got off with it! Last tank of round up of season.
I've been using rodeo from Monsanto

Just curious, you didn't have trice by fmc through your sprayer this year? It seems to coat everything inside the lines etc and terrible to clean out.

That tank and equipment cleaner is good stuff.

I have known people have a problem with a dirty tank or lines even after using all clear. You can't beat 'distance' between crops. I.e, you have been using a herbicide and fungicide mix on a cereal crop, then go and do another cereal crop with just fungicide before switching to say, OSR.

My 'spider-senses' don't like dirt cheap glyphosate products. Never have. Better to stick to brands and products you know well and with a manufacturer that will at least play fair if you have an issue.
