As in the title, does anyone run separate sprayers for Glypho and Broadleaf (Bin-die) applications?

I currently have 2 but one is a crappy wheeled one. Would prefer the backpack but is there residual effect from the Glypho even if it's cleaned out?

Gday Leon

I use separate spayers
I have one that has glypo in it pretty much always. Once I emptied it, cleaned it out and put bindie spray in it then sprayed a whole front yard of kikuyu. Ended up with the whole front yard pretty much on deaths door.

Luckily it was my front yard and not a customers. I will only use one sprayer for one type of poison now.

Thanks Glenn,

Exactly what I was trying to avoid!

On another note, how do you charge for domestic spraying jobs? Per hr, per tank, flat fee?

Glypho is easily water soluble, so in theory you could multiple wash a sprayer and you should be OK. (e.g. partially fill, shake violently, dump; repeat; partially fill, spray >2 litres of rinse through the wand; repeat; rinse, repeat). A couple of mls of Morning Fresh or similar in the first wash-out should assist in making it lemon-fresh and sparkly clean. :)

However, reality is a different thing.

Two sprayers is a better judgement. Sorry for reinforcing bad news, brother.

Charging for domestic spray jobs, I lean towards per linear metre multiplied by [(cost + difficulty factor) + margin]. Only you know your speed. Some stuff you can use a double headed wand on a back pack, but others need a 5 litre hand held for the entire job or for touch-ups. If you account for batch mixing time per back pack or hand held, on top of the linear rate, then you're on target.

Hope this is helpful.

Cheers - GardenGuy.

I would recommend 2 separate sprayers -- it is just so much safer & easier that way if they are not expensive pieces of kit.
AND if you apply NON-HERBICIDES ... have one that you use ONLY for that purpose.

True that Glyphosate is water soluble, and a detergent would help, but better to use an IONIC detergent (eg laundry detergent) as that will interact even more with the glyphosate to de-activate it.
The Morning Fresh is most likely a non-ionic detegent and will not de-activate the glypho.

Washup/decontamination after Bin-Die is a different matter.
From reading the MSDS, it is contains a hydrocarbon solvent and as such will tend to "cling" to plastic spray equipment (like oil/grease wants to stick to many plastic surfaces).
The best way to deal with this is to use a good detergent that will deal with oily/greasy things --- laundry detergent is once again not a bad choice.
One can also use washing soda (avail in supermarket as "Lectric brand") and some of the websites below advise that chlorine bleach is effective decontaminant.

There are also some specialist Ag-chem products on the market for sprayer cleanup - brands such as AllClear, SprayMate etc.

The following websites (which are written primarily for farmers) give some useful information and the methods for decontamination for the different herbicides/pesticides.

Be aware that Bin-Die contains MCPA in the ESTER formulation and take that into account when reading these docs.

I used to have three spray bottles when I was doing it. One for Glypho, one for broadleaf and one for insecticide/fungicide/Wetnforget (stuff that wouldn't kill plants if not completely cleaned properly) for shrubs, Roses etc. I was doing a fair bit of it for a while and didnt want to risk damaging any plants with residue, especially when I had my apprentice who may not have taken the same care as me with cleaning.

while i would recommend using separate containers
15ml/L of glyphosate 360 in a 10L container even if after rising out you have 100ml of mix left in the container this is only going to leave a mix rate of 1.5ml/L if you are going to use the same container remember to pump and use the wand so any residue in either the pump or hose is cleaned out i would recommend a strong detergent mix swished around then partly emptied through the wand do this at least twice then rinse out with clean water a couple of times remembering to use the wand to make sure it has fresh liquid in it otherwise the 1st thing you spray will probably die

I'm the same can be a big risk other wise. Pain in the bum carrying all the extra sprayers but its your safest bet.

Same for me,3 x 15lt for glypho,turf spraying and insecticide/fungicide
Plus a 5lt for expensive stuff like Sempre for small areas of nutgrass etc

When I did my chemcert they recommened 3 rinse cycles to make sure all residue is removed

I spray thousands of litres of glypho per year and amicide or similar with the same sprayer. Always rinse twice and flush wand several times. I would only use a separate sprayer for fung and insect.
