Casoron 4G is a selective pre-emergence herbicide that prevents many 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.

APPLICATION INSTRUCTIONS
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.

5 stars for Casoron
By Dorothy on 04/15/2017
This was a gift sent to my son to rid the hill from weeds and having to maintain each spring, but I used this product in Montana when my home had small gravel surrounding it. Spread this all around as spring was arriving and NEVER were there any weeds growing all around my home or down the driveway. Everyone wondered how I did that!!

Just wondering if I will still get new raspberry sprouts after I used Casoron to control weeds in my raspberries.
You can use Casoron 4G Herbicide granules around estblished raspberry plants. Per the product label, "For control of annual weeds...Use only on established plantings and do not apply more than 100 pounds per acre. Do not apply during new shoot emergence. Thoroughly incorporate granules into the surface through watering-in." So you would apply either before or after new shoot emergence of your raspberry plants.

Mulch was used to keep weeds from spreading or does it need to be directly on soil to work?
Casoron 4G Herbicide is best applied directly to soil and then watered in to create the barrier needed to prevent weeds from emerging. To help get the Casoron granules to the soil in mulched 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.

Unfortunately we do not have a product that will control for up to 2 years, but we do carry Eraser Max Super Concentrate Herbicide that will prevent regrowth for up to a year. It will kill any weeds that are actively there since it is a non-selective post, but also prevent regrowth of weeds just like Casoron 4G Herbicide
The ?Casoron 4G Herbicide? product label ?states: Do not plant rotational crops, on which dichlobenil is not registered, in treated soil within one year of application. It is not labeled to be used in soil where vegetables will be planted so we cannot recommend you do so.

According to the manufacturer, Casoron 4G Herbicide is not corrosive to metals. This product should only be applied in the labeled places and must be watered in immediately after application to avoid the active ingredient becoming volatile. Please be sure to thoroughly read the product label, as this product does contain very specific safety instructions.

I have large flower beds that get grass in spots. The main plant in them is ivy, growing on the ground. Will Casoron kill the ivy?
Casoron 4G Herbicide does not kill anything actively growing as it is a pre-emergent only. It does not list that it will prevent any type of ivy as it states ivy as tolerable on the label so safe to use over.
