Turf Grsses and weeds out of gravel drives

[sunslave]

Hey everybody,

I live in Indiana,
We Hoosiers, have a lot of gravel drives, parking areas and what not.
I have used Round Up and Ortho brand "Triox" to keep the grasses and weeds from growing in drives with limited success.

The Triox really works, but one Quart mixed with a gallon of water only properly treats 75 square feet. and at $25 ~35.00 a gallon, that does not seem very cost effective.

Round Up works after the unwanted vegitation has sprouted. I don't want to spray every time it rains. <img src=icon_smile_blackeye.gif border=0 align=middle>

I want a one shot, one kill, (for 3~4 months) kinda stuff.

Any suggestions?

My suggestion is to hire a licensed applicator.

If you are willing to buy that crappy overpriced consumer Ortho product at $35/gallon of solution something is not right.

One needs insurance to apply these products commercially. Normal "lawn cutter" insurance does not cover the damage caused by the misapplication of pesticides.

There is no such thing as one-shot 3-4 months stuff, new weeds will sprout. That's why our business is maintenance, we maintain landscapes. Round up is most popular, I prefer the dry mix.

Sorry bucko but you need to get some education. A ****tail of 3 different products (all available at Lesco) will give up to 4 months control.

If your ornamental weed control program is a jug of Roundup you are way behind the times. Many new products have been introduced since the dark ages that will control a variety of different weed issues in many types of plantings. Only two visits per year (up north) are needed for almost complete control.

But unfortunately this is ROCKET SCIENCE and one can do a lot of harm to desirable plants if they have no understanding of how and why all these products actually work.

It will cost more if you are just using Roundup. The cost of the materials and labor to just spray round up every tow weeks is more vs. during it right way the first time.

Hello Everybody:

I'm Sure by Now there is Several Chemical Apps that Will Kill Weed Seeds when they Germinate. I Don't Know Now, this is Now out of My League?

In the Dark Ages (Mid to Late 80's) I Used Surflan, Surflan Kills Weed Seeds When they Germinate.

I Used 2 .oz of Each Per Gallon, Round up, Crop Oil (Surfactant) & Surflan! Yes it was a Little Steep on the Round up but...

The Little Orange Tint in the Surflan, Helped me SAVE When Spraying. If you like me when you are Spot Spraying you will go over Some of it Several Times!

The Orange Tint Went Away after the Rain Soaked the Surflan into the Ground. I did lot of Parking Areas, Cracks in Drives & So Forth!

The Surflan was Used in Beds Too, With no Affect on Woody Ornamemtals, I Used it Quite a bit in Beds, Most Others used Ronstar, I used the Surflan because of Me Spraying it So Much for Weed Killer Mix I Used, So I Bought it in Quantity.

Always Read the Label? <img src=icon_smile.gif border=0 align=middle>

Surflan is old school. The plant the makes surflan blew up a while back and the price is through the roof if can even find a jug on a shelf somewhere.

Orange stain on sidewalk NO good No good.

Hi Sunslave,
There are many pre-emergent herbicides on the market that are effective in weed control. It does'nt surprise me that the Ortho and Round-up has'nt worked for you. Retail solutions of Ortho are weak and many weeds have developed a tolerance to Round-Up(glyphosate)especially nutsedges.

If you do not have a Pesticide applicators license, call someone who does. Some effective pre-emergents are Pedulum(pendimethalin), Snapshot(isoxaben+trifluralin), Regal OO(oxyfluorfen+oxadiazon), Treflan (trifluralin) and Surflan (oryzalin).

The orange dye is kind of unattractive when sprayed,but is beneficial as far as knowing WHERE you have sprayed and it washes away quickly. The good thing about Surflan is that it can be tank-mixed with Round-Up to provide both post and pre-emergent control.

You have to be VERY careful with pre-emergents. They cannot be applied to the root zones of newly planted grass or plants and most are not recommended for bedding plants. However, for gravel applications it should work fine. Like I said, if your not licensed, contact a professional who is, they can suggest the best method for you.

Ahhh, love to be spraying this stuff all over the place. Can anyone honestly say they are doing their clients a favor by introducing this into the soil around their houses? Do they have children? If so, how can you sleep at night.....

Product: SURFLAN AS
Active ingredient: ORYZALIN 40.4%
Other ingredients: 59.6% Propylene Glycol <b>(ever hear of antifreeze??)</b>; other ingredients withheld as trade secrets by the manufacturer. Type: Dinitroaniline HERBICIDE(systemic)
Mode of Action: Inhibits seed germination; interferes with cellular respiration and may inhibit microtubule polymerization/function, which is important to numerous vital cellular activities.

TOXICOLOGY
Oryzalin, <b>is considered a possible human carcinogen by U.S. EPA</b>, which has ranked it group C, meaning that there is evidence it causes cancer in animals. <b>Tumor formation was observed in rats at the lowest dose tested</b>, including both benign and malignant thyroid, skin, breast, and other tumors (Caltrans 1991). Oryzalin is also suspect as a carcinogen because it is structurally related to 2,4 diaminoanisole sulfate, a chemical which causes similar malignant tumor formation in test animals. Other related compounds have shown carcinogenic properties (EPA 1989).

<b>The liver, blood and blood forming tissues are the targets of damage caused by oryzalin; it is toxic to bone marrow (Lappe 1988). Animal tests have revealed adverse changes in blood chemistry, cholesterol levels, anemia, liver, spleen and bone marrow (Caltrans 1991)</b>.

<b>Oryzalin contains a contaminant (inadvertant byproduct of manufature) ingredient, N nitrosodipropylamine (NDPA), a confirmed human carcinogen</b> listed by the Office of Environmental Health Hazard Assessment under California's Proposition 65 (EPA 1986b). EPA is concerned about the toxicity of ammonium 3,5 dinitro 4 di(n propyl)amino benzene sulfonate, another contaminant of oryzalin (Caltrans EIR 1991).

<b>Lab animals exposed to oryzalin showed chromosome mutations (EPA1989).</b>

Prolonged exposure may cause irritation or allergic reactions in some individuals. Higher temperatures may generate a vapor level sufficient to cause irritation and other effects when inhaled. (Elanco Products, no date[recent])

Stone,
Would love to hear the contents of the Lesco "****tail" that you describe. Any clues?
