Hi-Yield Nutsedge and Horsetail Control is a selective post-emergence herbicide that kills both horsetails and nutsedge on your property in both cool and warm season grasses. The product is absorbed into the plant in 1-2 days and you will see browning or yellowing of the plant within 10-14 days. Each pouch of the product weighs 0.03 oz. and the herbicide works best when mixed with a surfactant, like Hi-Yield's Spreader Sticker. This helps the product penetrate through the waxy coating of the nutsedge and all the way through the target weed.
Is there an ideal outdoor temperature that Hi-Yield Nutsedge and Horsetail Control should be sprayed?
When can I pull it out the garden? Just wondering if the product will work if it’s 70’s outside or if it needs to be warmer. I have used this product several times and can’t seem to get rid of this horsetail. At what point can you safely remove to weed after spraying to ensure no further spreading of the spores?
Per the label: For post-emergent control of Horsetail (Equisetum arvense) apply after Horsetail has leafed out. This product will control Horsetail that is less than 6 inches tall and suppress Horsetail that is greater than 6 inches tall. Herbicide symptoms are likely to show within 2 weeks as a necrotic ring at the base of the plant, even though the leaves and stems remain green and a deep leathery green in color.
