For control of susceptible woody plants and to prevent or control regrowth from cut stumps, Helena Crossbow Herbicide states 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. That would be 4 gallons (512 oz) to 96 gallons (12,288 oz) of kerosene to make a total of 100 gallons. That would break down to 5.12 oz of Helena Crossbow to 122.88 oz of kerosene to make a 1 gallon spray mixture

No Crossbow Herbicide would not be safe to apply in creek beds at all.
Helena Crossbow Herbicide can be applied in any area you have weeds that need to be controlled that are listed in use areas on the label. The sun does not have a direct effect on the time it takes for weeds to die as long as the mix rates are applied per the product label however applications should be made in early morning or late afternoon evening so avoid any accidental injury to desirable grasses.
2,4-D compounds are systemic herbicides and will translocate slowly down to the roots. Helena Crossbow containing the 2, 4-D active ingredient would work with the same mode of action however St. Johnswort (goat weed) is not listed on the product label as one of the weeds it will control therefore we cannot advise on the efficacy it would have on the weed.
Some alternative options that are labeled for St. Johnswort (goat weed) would be Bonide Poison Ivy and Brush Killer BK-32 Concentrate (Dicamba and Triclopyr) , Chaparral Herbicide (Metsulfuron methyl) or Alligare 2,4-D Amine Herbicide( 2,4-D). Also using a non selective glyphosate product such as RoundUp is commonly used to spot treat harder to kill weeds.
Review the product labels for application rates and information on Tank Mixing Herbicides if allowed for better results.
St. Johnswort is best treated by spot spraying when it is in flower (Nov–Jan) because it can be easily seen then and is at its most sensitive period to herbicides. Spraying should begin six to eight weeks after substantial rain and when St John’s wort reaches the 50% yellow bud – 50% open flower stage.
If you would like to get your soil tested, we recommend consulting with your local extension office.
Once Helena Crossbow Herbicide has dried it is safe for chickens to return, typically after 4-6 hours.
Helena Crossbow Herbicide is not labeled for Japanese climbing fern or Old World climbing fern. Unfortunately, there currently are not any selective herbicides labeled to control these invasive vines. Using a non selective such as Roundup QuickPro that contains atleast 41% glyphosate is recommended and repeat application will be needed. Avoid contact with desirable plants by directly spraying or brushing the application onto the vine.
Please review this article from Alabama A&M Extenstion Office for more information.
The label for Helena Crossbow Herbicide does not mention using it with the method of hack and squirt.
You would not want to apply the Helena Crossbow Herbicide to any plant you didn't plan to kill completely. The systemic nature of the product would very likely move into more areas of the plant than just where you applied it. Products that are plant growth regulators would typically be used to reduce spread or new shoots/growth from plants that have been trimmed. The Sucker Punch RTU is a popular choice to stop "suckers" - new sprouts from a cut branch or stump. You can review the full Product Label Here prior to purchasing to see if you feel it would fit your needs.
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.
Crossbow Herbicide is not labeled to control cattail. You may check out Roundup Custom Aquatic Terrestrial Herbicide as it may be applied to ditches to kill cattail. Please refer to product label for further instructions.
Helena Crossbow Herbicide will damage ornamental plants such as flowers, shrubs, and trees, so you should not apply it within the drip line of those plants. Crossbow also has soil residual, so you would not want to apply this where you intend to transplant new ornamentals, either. Keep in mind that Crossbow is labeled for control of horseweed (marestail, an annual weed), but not horsetail (a perennial weed).
You could use Sedgehammer Herbicide for control of young horsetail in areas with turfgrass or around woody ornamentals.
Helena Crossbow Herbicide is not labeled to control wintercreeper/Euonymus/spindle though the active has been used for control. That is a kind of evergreen plant, so you would likely need to cut the plant down and then immediately treat the cust with glyphosate or triclopyr to prevent regrowth.
Keep in mind that a product that can kill the wintercreeper can also harm your vinca minor (or other groundcovers) and the crepe myrtle. So physical removal and/or careful spot treating with a non-selective herbicide will pose much less risk to the desirable plants.
Although not directly listed on the label, Crossbow contains Triclopyr which is known to be used on wintercreeper, we just cannot confirm that it would kill it since off label. Products containing Glyphosate are also used for treatment.
Crossbow Herbicide could injure desirable ornamentals plants. Care should be taken to avoid any contact and very carefully spot treat the weeds directly in these areas.
Hay may be harvested 14 days after applying Crossbow.
Other than wearing normal work gloves to protect your skin from scratches and sharp parts of the plant when handling it, there would not be any need for gloves from a chemical standpoint as long as the surfaces aren't wet from an application of Helena Crossbow Herbicide. If everything is dry you can handle the treated bushes like normal to dispose of them.
