Casoron 4G is a selective pre-emergence herbicide that kills variety of weeds and grasses. Casoron 4G controls weeds before they emerge from the ground, by forming an herbicidal vapor barrier in the upper layer of the soil when activated by rainfall or irrigation water. Casoron 4G should be applied before weed seed germination and emergence from the soil (usually from mid-winter to early spring). A single application will usually provide season-long weed control.

Perennial Weed Control
Apply CASORON 4G as a soil surface treatment in late fall from November 15 to February 15. Old weed growth should not be removed before application. Do not make surface application to areas which have been cultivated during the fall or summer prior to application.
Annual Weed Control
Apply CASORON 4G either in early spring before seeds of annual weeds germinate or after cultivation has removed the growing weeds. Distribute granules uniformly over the soil surface. If treatment is followed by application of 1/2 to 1 inch of water by overhead irrigation, the lower rates are recommended. Shallow incorporation immediately after application is recommended in southern areas. In other areas, shallow incorporation or sprinkler irrigation is suggested when applications are made during periods of high temperature.
Nut Sedge Control
CASORON 4G can be used for control of nutsedge in non-crop areas only. Apply recommended rates and incorporate immediately to a depth of 4 to 6 inches. Seasonal control of annual weeds will also be obtained with this application.

February 28, 2011 Ruth asked:
QOur church has a gravel parking lot in AZ. What pre emergent can we use to prevent tumbleweeds from coming?
ACasoron Herbicide will be a good choice to control Russian thistle (aka tumbleweed). Treating gravel lots can be tough because it is hard to contact the soil and the soil is usually very dry. To help get the Casoron granules to the soil you must heavily irrigate the area after the application. Casoron is a mild soil sterilant, so it is very important not to put it in areas where it will contact desirable plants or in areas where you will soon want to grow new plants.

QWill your product diclobenil kill bamboo?
My neighbors bamboo is growing under my fence and I want to get rid of it, however I have plants growing along my fence line, will I have to dig my plants up or can I dig down around the plants to put this diclobenil in the ground. HELP What do you recommend? HELP HELP HELP
ADichlobenil, the active ingredient in Casoron 4G Herbicide, is not labeled for bamboo and may not be an effective solution for your needs. We recommend that you contact your local cooperative extension office and speak to the master gardener on staff for further advice. Bamboo can be VERY difficult to eliminate but the master gardener may have some helpful tips for you.

Keith from Springfield, Illinois asked:
can this be used to treat sewer lines to get rid of roots?
ANo, Casoron 4G Herbicide is not labeled to be used in sewer or septic lines to kill root systems and advises against that use on the product label. However, we do have Hi Yield Root Killer that is labeled for that type of application and use. Hi-Yield Root Killer dissolves the roots that are intruding into the pipes without harming those trees and shrubs outside of the lines. This product will not corrode sewer or drain pipes that connect to septic tanks and will not kill the necessary bacteria needed for septic systems to function. Please read and follow all label driections.

John from North Idaho asked:
QHow far away from pasture grasses should Casoron 4G be applied to remain safe for haying?
A Casoron 4G Herbicide when applied as directed will bind tightly with the soil. The most it has been proven to drift is up to one foot. It is best if applied when a heavy rain is NOT present in the following day or two after application.

Janie from Port Ludlow, Wa asked:
QWe have a large yard. Is there a weed control product (Caseron) that lasts a year?
If so, which month is best to apply? The Caseron does not last an entire year. I know you need to put it down before the weeds begin to grow again, but I'm hoping we don't have to apply it twice a year. It sure helps prevent weeds growing; which saves on Roundup usage. Thank you for answering the question and any advice you might have.
A Unfortunately there is not a weed control like Casoron that will provide you year long prevention from weeds growing, the only products that provide year long control are bareground herbicides such as Pramitol. Casoron is labeled to give season long control, but you will need to reapply because it does not have and post emergent qualities. Dimension 2EW gives pre and post emergent control for labeled weeds.

Sue from Warrenton, Or asked:
QIs Dichlobenil mainly a pre emergent?
Will this also kill vegetation? Dichlobenil 2% is also sold by a major brand as a vegetation killer, but then sold also as Casoron as a preemergent only. I find this confusing. I would like to a product that does both actually.
Dichlobenil in Casoron 4G Herbicide is a pre emergent. There may be other ingredients in the vegetation killer product that make it a pre and post emergent. We would recommend to contact the manufacturer of that product for the active ingredient.
May 8, 2014
Sue from Warrenton asked:
QDoes the active ingredient dichlobenil only act as a preemergent?
There's another product by Lilly Miller with the same ingredient that's sold as a vegetation killer at 2% and I've used it as a vegetation killer in the past, so I'm a bit confused.

Dawn from Gig Harbor, Wa asked:
QI spread Casoron 30 days ago. My puppy mouths grass and weeds. Is it safe?
Casoron was spread on our vacation lot at Ocean Shores, WA 30 days ago as a prevention for new weeds. There are random weeds and grasses that had already emerged all over the lot. My 7 month old Golden Retriever puppy mouths everything. He will pull weeds and shake them, pull at branches of woody shrubs, and sometimes eat long grasses in the treated area and nearby areas. Is it safe for him to be in this area. Package says no livestock grazing for 12 months??
Casoron 4G should not harm pets when used as directed. You are right, this product is not to be used in grazing areas. Since you said that your puppy eats the grass, we recommend contacting Chemtura 800-423-8569. The manufacturer will be able to give you more specific advise on their product.

Pat from Wa asked:
QCasoron vs homedopot
the 25lb bag of Casoron on your site is 109$; Home Depot carries lillymiller Casoron 8lb bag for 25$. 3 bags from HomeDepot = 75$ for 24lbs. what is the difference between the Home Depot Casoron and your listed Casoron for the extra 30$ ?
A We apologize but we do not carry the version that Home Depot carries since all we carry are professional grade products, therefore we cannot accurately compare the two products for you. You are more than welcome to contact the manufacturer of the Casoron 4G we carry to see if they can tell you the difference between the products. You can reach Chemtura at 203.573.2000.

Fran from Leavenworth, Wa asked:
QCan Casoron 4G Herbicide be used around established roses and ornamental grass
Casoron 4G Herbicide would work great around the roses. We would not recommend to use it around ornamental grasses, because it could cause injury. Casoron 4G Herbicide works by causing "tissue damage" to the roots. Since, grasses are rooted shallow, this product could stunt the ornamental grass growth.
