I bought some cleth last year for the first time to treat grass around my spruce and pine. The kind I got is shown below. I mixed 0.8 oz into a 2 gallon hand sprayer. I also mixed in 1.0 oz of crop oil. I did not hurt my trees, but i also didn't hurt my grasses much at all. I could tell I set them back a hair a month later, but I never did get a kill. Temps were right, dew was off, I think I just mixed it too weak. Never had water problems in the past, but I'd be willing to just buy some clean water if anyone thinks that was the problem. Can anyone tell me how much cleth concentrate and crop oil to put in a 2 gallon batch ? I've read the book front and back multiple times and cannot figure it out. I've got a piss pile of work into laying out and planting these spruce and I want to make sure they get the edge they need to get moving. www.keystonepestsolutions.com/index.php?main_page=product_info&products_id=477&gclid=CjwKEAjw5M3GBRCTvpK4osqj4X4SJAABRJNCxrYt4anB9iODZ6RusFBPUx2dYXoCsfuEaWbD4ST1TxoC8Qfw_wcB |

How big of an area did you spay? All of these chemicals give an amount per acre.
Fyi, point .8 in 2 gallons is towards the low end of the recommended rate for spot spraying. You had half of the recommended amount of crop oil.
Spot Treatment
When using hand sprayers or high volume sprayers utilizing hand guns, mix 1/4% to 1/2% (0.33 oz. to 0.65 oz. per gal.) PS Clethodim
and treat to wet vegetation, while not allowing runoff of spray solution. For uses requiring crop oil concentrate, include crop oil
concentrate at 1% (1.3 oz. per gal.) by volume. For uses requiring non-ionic surfactant, include non-ionic surfactant at 1.4% (0.33 oz. per
gal.) by volume).

First of all, what grass are you trying to kill?

First of all, what grass are you trying to kill? I can’t ID the grass. I know it isn’t a sedge, and it ain’t canary. Beyond that, all I can say is it’s shorter and only gets about 2’ tall. |

Quack or Fescue maybe? It won't kill either. But You probably need to up your rate anyways. And any grass over 1"-2" tall won't kill either very easy. |

Here’s a picture of it. If the leaves feel rough like sand paper its quack. Won't kill it with Cleth. |

With trees that small can you cover them with a 5 gallon bucket and spray roundup or what ever ?

From my experience you need to spray grass early in the spring before they get big and mature to have any luck. We have been spraying spring and fall on a bunch of trees with success however last year got busy and didn't spray early enough in the spring so we sprayed June and had zero effect on the grass. Most of ours is timothy grass not sure if that matters or not.

Thanks for the feedback guys. This has been bugging the shit outta me since last spring. I made a special trip to hit this the moment it was warm enough.

To Mo's point, do you need to weed wack around the trees and then spray when the grass is short? Even in the spring I think you may need to clear last years growth so you can get a good coating on the new growth.

So your saying it may be unnecessary, but is there a type of grass or herbicide where doing that would be something you would not want to do? |

I've had the same results with Clethodim. I think I just sprayed the grasses too late in the spring and it didn't get the kill I was hoping for. I can't remember offhand what concentration I used, but I know I followed the directions. I was trying to kill the grass out of a clover/chicory plot and it didn't work nearly as well as it does in the magazines.
With spruces and pines I've found that if they can survive the first summer they are going to live. I really wouldn't worry about spraying them unless you were mostly looking to get out of the house.
