    Does anyone know the rough particle size of that white cloud of emulsified herbicide when you add water to say speedzone or momentum fx2 ?

    i want to prolong the life of my diaphram pump, so i figure, if the particles that make up that white cloudiness in a tank mix are below say.. 75 micron, i could put a 100micron fuel filter between the tank and pump.

    dont care what units you have it in, i can convert.
    and i am spraying very low volume , so flow wont be an issue.

    may seem like overkill, but i know for a fact the pump life would drastically improve.

    if all you guys with permagreens found that say, a 150 micron fuel filter, would let all the emulsified herbicide through, and fit one prior to your pump,
    you would see an amazing increase in pump life.

    anyone with a chem background, or just knowledgeable, have even a rough guess as to the size?

    looks like the range is 1-30 micrometers. so 0.001 mm - 0.030 mm

    so my 75 micron (0.075mm) fuel filter should work.

    Let me guess--you are an engineering major, right?
    Go for it. However i am dubious that this system will work. Please let us know.

    hahaha ya, electrical; good call. I put the filter on and sprayed some lawns today, so far so good:), I will PM you if it works perfectly once i've ran many different products thru it.

    Hey! you ever use a thickener/drift reducing agent? My sales rep told me to go to walgreens and get the stuff they use to thicken up liquids for people who can't swallow easily.... he's a moron, it's just corn starch and maltodextrin. looks like it would mess my system up good.
    What about like, propylene gycol? u know.. the stuff thats in everything from cough syrup to shampoo that thickens it up.

    you know if dimension will block dandelions? label doesn't say.

    I'm just full of questions today arent I? :confused::laugh:

    Dandelions are best killed in fall--use Lesco Threeway. Never heard theat Dimension worked on dandelions.

    Propylene glycol? Sure it is in my shampoo, but it is about 20th on the list of ingredients.
    If you want to thicken your solution on windy days use a drift retardant.

    ya ya ya.. i use a carfentrazone + triclopyr + 2,4-d ester mix to kill all weeds; dandelions included. was talking pre-emergent.
