Application Information

Timing of Applications:

Apply PS Clethodim post emergence to actively growing grasses according to rate table instructions. Applications made to grass plants stressed by insufficient moisture, or hot or cold temperatures, or to grass plants exceeding listed growth stages may result in unsatisfactory control. Do not apply under these conditions.

In arid regions where irrigation is used to supplement limited rainfall, PS Clethodim should be applied as soon as possible, after irrigation (within 7 days). In arid regions, a second application of PS Clethodim will generally provide more effective control of perennial grassweeds than a single application. Make second application to actively growing grass 2 to 3 weeks after emergence of new growth.

Cultivation of treated grasses 7 days prior to or within 7 days after application of PS Clethodim may reduce weed control.DO NOT APPLY PS Clethodim if rainfall is expected within one hour, since control may be reduced.

    5 of 5 stars  Used on Food Plot
    By Stevep in Pulaski, TN on 06/15/2015
    Verified Purchase

    I purchased Clethodim herbicide to put on my deer food plot of Alpha Rack Plus where the local grasses were taking over. The first week I could see the grasses starting to die. The second week they were dead. Works great. Purchasing from DoMyOwnPestControl was easy and fast. I ordered on a Sunday online and had the product a few days later with standard shipping. The price was the same or better than competitors.

QWhat is the mixture rate of Prime Source PS Clethodim Herbicide per gallon of water?
I want to kill the grass in my clover food plots. They have become over run with the grass that grows wild in the woods. I will be suing a 4 gal. back pack sprayer.


The mixing ratio of Prime Source PS Clethodim Herbicide is 0.33 to 0.65fl. oz. per gallon of water for spot treating. We would recommend using a surfactant if necessary.
