Product Overview

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!!

    Great Herbicide

    By Stacey on 06/03/2018

    We spread this herbicide through our juniperus every year at the end of winter and it keeps the Crown Vetch from growing without fail!

    Great for preimergence

    By D.b. on 09/06/2019

    This is the best I have found for keeping growth out of areas like landings, paths etc. It's well worth the money.

Q
Can I apply Casoron 4G around bulbs?
A

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.
