Clethodim 2e to selectively kill grass in clover plot

[birdog]

The folks at Drexel told me if you mix 2-4db and cleth together to use cleth at the max rate. Apparantley 2-4db will reduce or weaken the effectiveness of cleth.

I was needing to kill NWSG in my pollinators. A Purdue study can be found on line. Good info but what they say to do was use Clethodim full strength and then two weeks later second application full strength. Killed 75% of 16"mature grass. As posted make sure its not yellow nutsedge instead on grass.

AND DONT FORGET TO ADD SURFACTANT!!

FTR...cleth label says no more than 1 application annually, no more than 16 oz. in an app, and no more than 16 oz. per acre, per year on clover

Yes, and the college research said different. When I get time will try to find and post. Did not have any effect on CRP pollinators.

I don't question that, but the label is the law. Only reason I posted the info.

Have the information from Purdue I followed printed out at farm. This is some good info I found on line.

What does what mean? The label is the law when it comes to herbicide applications.

I'm pretty sure if you have a commercial applicators license and don't follow the label on a pesticide you can lose the license.

In and around water I can see that.

Herbicide manufactures are dealing with many variables and easier to say no more that 16 oz a year knowing lawyers think they have deep pockets.

I sprayed my clover plots today with a 16 ounce per acre solution of Cleth. I’m anxious to see how it turns out. I’m never sure how many gallons per acre I should use. I believe the label says 5-40 gallons per acre. I was 10 per. I feel like my sprayer is getting good coverage at that rate, but time will tell.

I always recommend calibrating your sprayer. Otherwise you're just guessing.

Mine is calibrated, but the total amount of applied solution (water and herbicide) is dependent upon your speed and PSI settings. I could go 2mph at 20PSI and my tank would cover 2 acres, or I could run 8mph and the same tank would cover 5 acres. I’m never confident on total solution applied per acre. I see lots of references of guys using at least a 25 gallon tank per acre solution, which seems high to me. I guess I’ll find out in a couple weeks.

Nozzel is a nother variable when spraying. I always spray 10 GPA because I need to haul water. I get good coverage for most aplications but if had well would like to try 15 to 20 GPA when spraying stresed or tall vegtation.

Speed and sprayer psi are all a part of the calibration process.

I used the 1/128 method to calibrate my sprayer. I need 20ga of water to cover 1 acre with my tractor set at 2300rpm in low gear.
