Crossbow Herbicide is specifically designed to kill brush, vines, woody plants like trees, and broadleaf weeds without harming grasses when used at the labeled rates. It will not, however, kill or control moss as moss only grows in areas where you have too much moisture and poor soil conditions where the PH levels are off and the soil is too compacted. Renting a core aerator and running it through the area you have heavy moss concentrations will greatly help. If there are any tree branches keeping that area shaded that you can trim back or cut off then you will want to do this as well so you help keep the area dried out to prevent new moss regrowth. You can spray a moss control product like Lilly Miller Moss Out, however changing the conditions causing the moss is always the best way to go so that repeated sprays aren't necessary in the long run.

Q

Is Crossbow Herbicide safe to touch or cut the dead poison oak plant?
Once poison oak has died after spraying with Crossbow (say 2-3 weeks after), is it safe to touch the dead poison oak or is there residual urushiol in the plant? Looking for the safest way to actually remove and dispose of the dead plants. Thanks!

A

Even after killing the poison oak with Crossbow and is "dead", it still contains rash-producing oils and is recommended to avoid direct contact. Wear rubber gloves and handle dead plants carefully. Dispose of plants and rubber gloves in tightly sealed garbage bags. Thoroughly wash clothes in hot, s…

Clean garden tools, too, either by wiping them down with rubbing alcohol or by washing in hot, soapy water.

The product label for Crossbow Herbicide only lists that it can be used in non crop areas and specifically states: Do not apply directly to, or otherwise permit it to come into direct contact with cotton, grapes, tobacco, vegetable crops, citrus, flowers, fruit or ornamental trees, or other desirable broadleaf plants and do not permit spray mists containing it to drift onto them. Gordons Ornamec would be a better choice. This will eradicate grassy weeds but not clover. You may need to spot treat with a glyphosate product carefully like Killzall for the other weeds or manually remove them.

Bamboo is extremely stubborn, so it can take several steps to remove it completely. You can use Round Up QuickPro at the highest listed usage rate to help eliminate bamboo. You will be required to cut the bamboo down to a short stump and then apply the Round Up QuickPro. It can take several applications to achieve the desired results.

Through our research, glyphosate based products treat the problem best, however those products cannot be used in grazing pastures with animals. According to the Crossbow product label: Except for lactating dairy animals, there are no grazing restrictions after using this product. They should not be present during the application and while the surfaces are wet but can return when dry.

Crossbow Herbicide is labeled for what is called a cut stump treatment. A cut stump treatment is where you hack or saw or cut the tree or bush off down at the stump level and immediately drench the roots and/or cut stumps with a concentrated dose of Crossbow Herbicide. The important thing here is to immediately drench the cut stump after cutting, so you want to mix the product and have it ready to go immediately after cutting it. It may require 2 treatments.
