Cleth And Dawn....How Much?

[tootall71]

Going to be spraying cleth for the first time ever to try and get control of some annoying ryegrass before it takes over in one of my clover plots this year.

I have a 4 gallon backpack sprayer. Wondering how much Dawn to mix in with the Cleth. I'd rather not spend the extra $ on crop oil, so any help would be appreciated.

Open to any other tips on eliminating ryegrass in an established clover plot as well....

Give it a good squirt or two. I think Paul said about tablespoon in a 15 gal tank. I always just give it a couple of good squirts "after" filling the tank then shake it good. I figure it's soap I cant over do it. Rinse the tank good when your done.

I use 1/8 tsp per gallon so a 4 gallon sprayer would be a 1/2 tsp.

I wouldn't be afraid to put 3 oz of gly in 4 gallons of water with the cleth. If you get a low dose on the clover it may stunt it but won't kill it in the spring. Just don't spray heavy in one area. Wouldn't worry about building gly resistance since the cleth will be working on the grass at the same time.

Most back pack sprayer are 3 gallons. If 1 tsp = 0.125 oz, so how will adding 0.4 ounces of dish soap to a 3 gallon mix have any impact.

Would really like to understand at this level of chemical concentration, and type of equipment ... the advantage is?

I would just dilute the cleth and spray ... why over complicate this process?

Hey, if the tree huggers can clean an oil soaked duckling in a teaspoon of Dawn rather than holding it by the head and spinning it, it has magical powers.

For the 1/10th of 1 cent it costs, I'm using it.

Let's just say that, without an adjuvant, it's likely that most of the spray solution you apply to a plant is going to roll off the leaf. The reasons are myriad and almost vary by plant type.

Research provides clues into what type of adjuvant to use. Most recommendations are for the finished spray solution to contain a quarter to 1% of the total finished solution as the specified adjuvant. Read the herbicide label with particular attention to the target weed(s).

Interesting ... thanks for the info.

Dawn will be your surfactant/sticker for the clethodim. The dawn will break the surface tension of the grass and allow the clethodim to stick or adhere to the grass. It doesn't take much, so a couple of squirts in the sprayer will be perfect. Make sure you add the dawn after you fill the sprayer or you will fight suds really bad.

BB ... thanks for the simple "Mr Science" explanation ... makes sense now.

I always understood you should clean your sprayer out at the end of the season with some Dawn dish soap ... keeps bad stuff accumulating in the off season tha t clogs lines & spray heads.
