Casoron 4G Herbicide is a pre-emergent only and will not kill anything actively growing. Yucca is very tough! First you want to cut the plant down as much as possible. Then you can apply a stump remover like Fertilome Brush and Stump killer. It will take 1-6 weeks to kill the root system. You will still have to do your part by removing the stump. Fertilome Brush and Stump Killer will kill the root system and make the stump stop sprouting but it does not make the stump disappear. The exact wording on the product label is "To kill Stumps and prevent sprouting, apply the undiluted product with a paint brush or backpack sprayer to completely cover the freshly cut surface. Do not reuse paint brush. Wrap in several layers of newspaper and discard in trash."
You will need to wait 6 months before planting any sod after applying Casoron 4G Herbicide
While it would not be an issue to apply it when temperatures are in the 60s, Casoron 4G Herbicide is a pre-emergent herbicide, so usually summer is not an appropriate time to use this product. This is generally used in spring an fall to prevent listed weeds from germinating. If you would like to tell us more about your application needs, then we may be able to recommend a better product for you.
Yes, Casaron 4G Herbicide is registered for use and for sale to Arizona.
Casoron 4G Herbicide is not labeled for use in lawns and could possibly injure the turfgrass if applied. We are not aware of a pre-emergent herbcide that would prevent acorns from germinating due to oak trees also grow sprouts from the roots. Our recommendation for control would be to cut them off as close to the tree as possiblle at all and there is not a product we are aware of that can be applied to prevent them.
You can contact an local arborist or the Master Gardener with the Cooperative Extension Office for recommendations on any control methods they have found successful for your treatment.
Casoron 4G Herbicide is used to control weeds around blackberries and other similar species plants so it would not do anything to stop the neighbors blackberries from coming over onto your side of the fence. There aren't any herbicides that could prevent that from growing except those that would kill your neighbors plant.
The coverage for Casoron 4G Herbicide will vary depending on the weeds you are targeting (annual, perennial or nutsedge). For approved application sites listed on the product label, apply 100-150lbs per acre for annual weeds, 150-200 lbs per acre for perennial weeds and 250lbs per acre for nutsedge.
Since Casaron 4G is not labeled for use in a pond and is toxic to aquatic life, you will want to stay away by at least 25 feet from the ponds to keep any runoff from coming into the ponds.
We recommend that you contact the Casoron manufacturer directly as they are the experts on their product and they may be able to offer you some useful advice in this situation. You can reach Chemtura at (800) 423-8569
Thank you,
No, Casoron 4G Herbicide cannot be applied to aspargus or any other edibles.
An alternartive recommendation would be Monterey Vegetable and Ornamental Weeder that is labeled for asparagus as a single application.
Per the product label for asparagus, apply after ferns are removed but before spear emergence.
The product label for Casoron 4G Herbicide advises not to enter or allow workers to enter the treated areas until granules are thoroughly watered in and the soil has dried.
Normally, if the edible vegetation is not listed on the product label as an area safe to use the product around, it is recommended to keep the application at least 10 feet away from the area. We would suggest contacting the manufacturer directly for more information at (800) 659-6745.
A great option for tumbleweed pre-emergent control would be Casoron 4G Herbicide. 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. This product can be applied in late fall to prevent weeds as well.
Casoron 4G is a great pre-emergent product that is labeled for nutsedge in non-crop areas only. It is also legal for use in California. For annual weeds, 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. For perennial weeds, 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.
Products that could have the same active ingredient as the Casoron 4G Herbicide could have a different formulation of the ingredient or precentage but we do not carry any that are labeled for use in sewer pipes so cannot say for sure. The Casoron label specifically states: Do not apply this product as a sewer treatment.
This product is a pre-emergent granule that has to be watered into the soil to create the barrier and be effective.
Casoron 4G does not state on the product label that it is safe to apply around astilbe or perennial geraniums. We would recommend checking directly with the manufacturer to confirm if it can be used, they can reach Chemtura at 203-573-2000.
Casoron 4G Herbicide is a mild soil sterilant so can persists for some time in the soil. It would be recommended to wait at least 6 months to 1 year depending on how much run off affected the area.
Casoron 4G is not labeled for Mediterranean sage at all. We are not aware of any pre-emergents that are labeled for use on sage to prevent it from coming up or coming back. Most applications are done with a post-emergent herbicide that is used throughout the growing season to control it as it comes up. A product like Gordons Pasture Pro is labeled to control Mediterranean sage and can be used at up to 2 oz per gallon of water. Gly Pho-Sel Pro Dry 75 also lists sage in general on the label and can be used per the label at up to 7 oz per gallon. Gly Pho Sel is one of the highest percentage glyphosate (Roundup-type) products on the market but it is a non-selective herbicide so you will want to be careful with application if desirable vegetation is nearby.
No, Casaron 4G is NOT labeled to be used as an aquatic herbicide and will kill any aquatic life in your pond. Unfortunately we do not carry an algaecide to be used in small koi ponds. We recommend that you talk to a local koi pond supplier.
