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!!

Casoron 4G Herbicide should not be applied near trees that are less than 6 months and it should not be applied where granules can stick to foliage or accumulate at the soil line around the base of the tree per the product label.

We would advise waiting till Casoron 4G Herbicide has completely dried before letting pets back in the area typically after 4-6 hours. The product is also not labeled to be used around lake, ponds, or rivers. We would recommend staying 25 ft away from any bodies of water and do not water in to the point of runoff.
Casoron 4G Herbicide shouldn't kill established grass. However, we would recommend you using it in a small test area first just to be sure before using it as an entire broadcast over your enitire lawn. You could also contact the product manifacturer Chemtura at 800-423-8569 to get a more definitive answer.

Used Casoron successfully past 5 years but don't want to waste if too early without rain; or be too late
We recommend that you contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region. Typically pre-emergents such as Casoron 4G Herbicide need to be down before soil temperatures reach 55 degrees

The rate at which you apply Casoron 4G will be dependent on the weeds you are targeting and in what type of areas and around what type of plants you will be treating. You will need to look over the Casoron Product Label to find the rates specific to your needs which can range between 100-200 lbs of Casoron per acre.

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.

We apologize but are not familiar with that spreader as we do not carry it so do not know the settings to use. The rate at which you apply Casoron 4G will be dependent on the weeds you are targeting. You will need to look over the Casoron Product Label to find the rates specific to your needs which can range between 100-250 lbs of Casoron per acre.

Can I apply Casoron on the ground underneath all the dirt and soil when making my raised beds? My thought was to eliminate weeds from coming up through. Also does it work on morning glory and blackberry bushes?
We would not recommend Casoron 4G for raised beds or flower/ornamental areas as many species have not been tested over and it could cause damage to the plants. A better option would be Snapshot for a granule to put down in beds as long as they are not vegetables. Snapshot TG is ideal for ornamental and flower bed areas to prevent a wide range of grassy and broadleaf weeds from emerging. Normally you will want an application of this to the top of the soil though as if you only treat deep in the ground you will not have a barrier on the surface where your first weeds would start to grow and appear. Since a pre emergent is designed to create a wall like barrier in the soil, it needs to be applied after all soil and plants have been put into place as disturbing the soil after application will remove the barrier.

Casoron 4G Herbicide is not labeled to be used around bulb plantings, so we would not recommend this application. Gallery 75 DF can be used around ornamental bulb plantings 2-4 weeks after planting but prior to emergence of annual weeds. Per the product label: Gallery also may be applied following bulb emergence but prior to flowering and after flowering. For fall planted bulbs, apply Gallery 75 DF in late winter or early spring to weed-free soil surfaces. For bulbs, make a single applcation wtithin 30 days following planting and prior to bulb emergence.
