While Crossbow is labeled to to treat woody plants and vegetation, privet hedge is not specifically listed on the product label as a controlled weed. We would recommend contacting your local cooperative extension office to confirm whether using Crossbow Herbicide would be appropriate for this treatment, or for product recommendations that have been proven to be successful for others in your area.
Yes, Crossbow Herbicide is still being absorbed in the plant throughout that time period. We do normally recommend that you prune the plant before you apply Crossbow. It is recommended that you wait at least 30 days before pruning the plants once Crossbow has been applied. You can still cut the plant down after application.
Crossbow Herbicide can stay in the soil up to a year after application. We would recommend that you wait before planting in that area or to plant elsewhere.
Crossbow Herbicide is labeled for the control of most kinds of unwanted trees. On page 5 of the label you can fine directions on how to use for conventional basal bark and stump applications. For larger or established trees, cutting the tree and making a stump application will be the best way to treat.
Crossbow Herbicide is applied at a 1-1.5% mix (1 1/3-2 fl oz) rate for high volume foliar applications to control woody plants (elderberry and blackberry listed on the product label).
The manufacturer of Crossbow Herbicide does state that this product is rainfast in as early as 2 hours after application. It is common for most herbicides to be rainfast in 4-6 hours after application, which is likely why you saw that information given. We apologize for any confusion.
If temperatures drop below 55 degrees after Crossbow Herbicide has been applied, this may lengthen the amount of time it takes to kill the weeds.
Crossbow Herbicide is labeled for non-crop areas and could harm lilies. Depending on what you are treating for, you can use a product like Image 70 which is labeled to be applied over landscape ornamentals.
Crossbow should NOT be applied to water areas to treat cattails as it is extremely toxic to fish and not labeled for that usage. We do carry Rodeo Herbicide is a very popular glyphosphate herbicide for the control of aquatic weeds and plants including mature cattails.
Crossbow Herbicide is a very good option for briars. Please consult the product label to make sure it will be safe to apply around the other vegetation (if any) in the area.
Crossbow Herbicide can harm Bahia grass. Depending on what you are treating for, you can use Southern Ag Lawn Weed Killer with Trimec.
It is recommended that you apply Crossbow Herbicide when the blackberries are actively growing. This is most likely to occur for a period after full leaf in the spring to early summer when moisture and temperature are favorable.
Crossbow Herbicide is only labeled to be applied in non crop lands per the product label and it can last up to 12 months in the soil and inhibit seed germination or plant growth. We would recommend checking directly with Dow to confirm if you can plant in treated soil in February. Dow can be reached at 800-992-5994.
Crossbow Herbicide should not harm established trees if it is not applied directly to them. Take care to apply when the wind is calm to minimize drift.
The product label for Crossbow Herbicide does not address girdling specifically, so we would not be able to give you specific advice on this application. Per the treatment instructions for Conventional Basal Bark and Stump Applications: "...Mix 4 gallons of this product in diesel oil, No. 1 or No. 2 fuel oil, or kerosene to make 100 gallons of spray mixture. Spray the basal parts of brush or trees to a height of 15 to 20 inches from the ground...For better regrowth control, cut the larger trees and treat the stumps."
Yes, Crossbow Herbicide is safe as long as it's used as directed on the product label and your pets stay off the treated area until it has completely dried.
Crossbow Herbicide lists on the product label that it is toxic to fish and may be toxic to aquatic invertabrates. Drift and runoff may be hazardous so treatment should be kept at least 15 feet away from the shoreline to prevent getting into the water. A better option would be something actually labeled for use around aquatic sites such as Diquat or Rodeo.
Crossbow Herbicide is a post-emergent, and can be applied anytime the weeds or woody plants are actively growing.
Crossbow Herbcide is a post-emergent herbcide and will only kill the weeds that are actively growing at the time of application. If there are weeds under the soil that have not germinated yet, those weeds will not be affected by Crossbow. To treat weeds that are in the soil that have not germinated, you would need to use a pre-emergent in the spring/late fall before the soil temps reach 55 degrees. Another option is to continue to treat with Crossbow as the weeds emerge.
Crossbow Herbicide could harm very young grass and states on the product label not to use on newly seeded grasses until grass has established a good root system and is tillering.
