    I have bought nu-film and used it but it gunks up my sprayers like crazy. Is dish soap as good? Also wouldn't a laundry detergent be a better adjuvent than dish soap because it wouldn't bubble as much?

    Try an organosilicone surfactant. Valley Green Organosilicone or Helena's Silwet L77 are awseome especially for low volume machine like the PermaGreen. No gunking & much better results than detergents or"spreader stickers" that contain drying agents.

    What kind of equipment? When you say it gunks up the machine--do you mean it plugs screeens--or too much foam? If foam is the problem--like with my Permagreen--then buy an antifoam product--it really works. The silicone based wetting agents like Lesco Hawkeye (About $65 for half gallon) really work--you need only about 10 percent as much.

    what do you think about Lesco Hawkeye silicone wetting agent? Cost is actually about $48 per half gallon.

    I think the label must be wrong--it recommends 25 to 64 ounces per hundred gallons. Far more than comparable products like Sil-wet. About 5 times too much. Cost would be about $18 to $48 per hundred gallons. Way above the cost of the weed killer.

    I do not use it in Permagreen, too much foam.

    With the exception of a scent additive, Hawkeye, Silwet & our Valley Green OS are all exactly the same product.

    We sell the 1 gallon jug for less than $48. $96/gal is insane. When we first introduced Hawkeye (I worked for Lesco for 17 years) I was excited by the performance. You should see the results of Eagle+Organosilicone for Apple Scab! But the price...Ugh.

    Send me your real email address & I'll send you a copy of the specimen label. I don't have it hosted on the www yet so no link.

    From our label:

    VALLEY GREEN ORGANOSILICONE BLEND may be used in aqueous tank mix applications for these uses as follows:
    • Herbicides – use product at 0.25 to 0.5% v/v mixing concentration.

    From the Silwet L-77 label:

    SILWET® L-77 SURFACTANT has been found to be effective in agricultural
    applications at .025 to 0.25% v/v concentration. <Strange range there -SJ>

    From the Hawkeye label:

    LESCO HAWKEYE may be used in aqueous tank mix applications for these uses as follows:
    § Herbicides &#8211; use LESCO HAWKEYE at .3% to .5% v/v mixing concentration.

    Aside from Hawkeye, .25% v/v = 32 oz per 100 gallons.

    So the recommended rates are about the same for all three. I feel that 32 oz is overkill unless you're dealing with a glyphosate resistant crop weed. Selective herbicide mixes for turf wouldn't require this much to be effective.

    No need for a label. I have 2.5 gal of "Improv" left over from last year. After that I usually buy Capsil from Scotts, at a local dealer.

    But the full rate is too expensive in a high volume water plus fertilizer plus weed killer mix. I use 3 gal per 1000 sqft.
