The product label indicates that Casoron 4G may injure conifers if applied in a way that contacts the foliage. We recommend that you wear protective clothing, cut the vines, and then treat the fresh cuts with a brush killer such as Fertilome Brush Killer and Stump Killer or RoundUp QuikPro for best results and to reduce risk to the desirable trees.

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.

Please be sure to thoroughly read the product label, as this product does contain very specific safety instructions.

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
