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

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!!

My 13 year old dog was exposed to it many times during the day for 5 straight days before I found out it was not safe for dogs. Do you have any suggestions that I can relay to the person that requested this chemical?
If the pet was not in the area during treatment and while wet, it is safe for their return. If your dog had direct exposure to the product and/or wet surfaces, we recommend that you consult with the manufacturer regarding safety. OHP Inc. can be reached at 800-659-6745.

Casoron 4G Herbicide is pet safe if used as directed. Pets should be kept out of the area while the product is being applied and watered in, but can return once dry.

If Casoron 4G Herbicide is applied according to the label it will not be harmful to your pet. According to the product label, do not enter or allow persons or pets to enter the treated area until granules are thoroughly watered in and treated soil has dried.

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??

I don't have enough ground to roll my spreader. Weeds grow up through the stonewall and into the arborvite
Casoron 4G Herbicide is best applied with a spreader that can be set to a rate per area. We do have a few options for hand spreaders here as an alternative to push spreaders.
It has rained
Per the product label on Casoron 4G Herbicide it requires it to be watered in after application to incorporate granules into the soil. So the rain would not hurt the appliation. You would just need to let the application dry completely before allowing your dogs back into the area.

If not what steps do we take to get the lawn back?
Since Casoron 4G Herbicide was applied to the whole lawn, it will likely stay there for at least a year so you will not be able to reseed until next year. If you have any additional questions, we would recommend contacting the manufacturer directly. Their phone number is 800-423-8569.
