Crossbow Herbicide, although not specifically labeled for Autumn Olive, should knock it out. It may take multiple applications.
In order to kill a tree that size, you would get the best results cutting the tree down to a stump and treating the fresh cut stump directly. If the trunk diameter is less than 6-8 inches, then you could potentially do a basal bark treatment with Crossbow Specialty Herbicide.You would mix 1.25 to 5 ounces per gallon of solution, mixing in diesel No. 1 or 2 or kerosene, then spraying the basal part of the tree up to a height of 15-20 inches off the ground. If you do not need this much product, then could also use Fertilome Brush Killer and Stump Killer.
Yes, Crossbow is labeld for clover.
Crossbow Herbicide can injure the desirable tiger lilies if contact is make with them through spraying/drift. It is not labeled to control them so would not be recommended for that purpose. The best option for spot treating in beds is a non selective herbicide such as Avenger or RoundUp QuikPro, taking care to avoid spraying the ones you don’t want controlled, or you can hand-pull.
Crossbow Herbicide is not labeled to be used on residential lawns and can harm some types of turf. A better option for creeping charlie would be 3 Way Max.
Crossbow Herbicide could harm Liriope. Liriope is listed on the Fusilade II label as an ornamental that it can be applied over.
Crossbow can be toxic to fish and may be toxic to aquatic invertebrates. We recommend to keep at least a 10-15 foot distance (or more) away from the pond/body of water during treatment to protect any aquatic life.
Yes, Crossbow Herbicide can harm desirable flowers and some grass depending on the type.
Yes, Crossbow Herbicide works best applied to the foliage of target plants.
Applying herbicides such as Helena Crossbow Herbicide in higher temps can cause burning/injury to your turf and would not be as effective since the weeds are heat stressed and would not absorb well.
Unfortunately, chameleon or Saururaceae, h. cordata, is an invasive species that is very aggressive and difficult to control. Because this plant spreads from underground rhizomes, you will not be able to control it by pulling or mowing. I have not been able to find any products that specifically list this plant on the label, and there is very little information from US sources on management of this plant. We would recommend trying RoundUp QuikPro, a non-selective herbicide with two active ingredients, or Southern Ag Brush Killer. These are excellent active ingredients that will damage most plants. You would want to give either product 10-14 days to see results. Be sure to give the plants enough time to die completely before tilling or disturbing the soil where they were growing.
You do not want to reseed any sooner than 3 weeks after application of Helena Crossbow Herbicide.
Crossbow should not harm established trees but may damage younger trees if applied directly to them. To avoid injury, do not apply directly on or within the drip line of smaller trees and avoid the foliage and any exposed roots of mature trees. It is best to carefully spot treat the target plants to avoid injury to your desirable trees.
Crossbow Herbicide can be used now, if necessary, as long as temperatures are above 45 degrees. Crossbow Herbicide will be effective in 45 to 85 degrees Fahrenheit.
According to this extension article a product containing triclopyr or 2, 4-d would work on killing palmetto plants. Our Crossbow Specialty Herbicide - 2, 4-D & Triclopyr has both active ingredients and would work just fine. It could take a few applications to fully eradicate.
If Crossbow Herbicide or any product gets into your eyes you will want to contact the Chemical Emergency hotline in regards to what actions you need to take. You can reach Chemtrec at 1-800-262-8200 or you can also call the manufacturer directly at 901-761-0050.
The best method to remove woody plants and shrubs is to first cut down them down to their stump and apply Helena Crossbow Herbicide on the fresh cut or spot treat as best as you can. If enough of the solution contacts the young trees roots it could injure them.
Typically any wildlife living in that area is going to move out while you are doing any clearing, walking, towing, or spraying of a product in that area. Products like Crossbow are designed to be safe for people and pets once dry and the safety likely is the same for wildlife. This time of year with hot temperatures surfaces should dry quicker depending on how heavily you put it on the target plants. If you can find anything to do in that area for about 30 min after you spray to help keep the wildlife from moving back in for a bit they should be safe to return to their normal habitats and routine.
