Yes, Crossbow Herbicide can be used to kill dormant blackberry bushes and vines. You would apply to thoroughly wet upper and lower stems including the root collar and any ground sprouts. Treat at any time when the brush is dormant and the bark is dry. Best results have been obtained with late winter to early spring applications. Do not treat when snow or water prevent spraying to the ground line. You will use 1.5 gals./acre broadcast application or 1 to 1.5% mixture. Please refer to the product label for complete mixing and application instructions.
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. It does not list lilac as a tolerable species.

If you are planning to use a product like Crossbow Herbicide you would typically want a late summer/early fall application for some of the best results with a post-emergent heribicide. Wild carrot can be difficult to completely get rid of due to their seed cycle, so dilligence and product rotation will be needed, if possible. I have linked for you below a really helpful guide on Wild Carrot and it goes over its life cycle, timing and ingredient recommendations from Michigan State University through their tests and what they found successfull.

It is also a vegetation management product, which means that it is not very selective, so it will kill almost anything that it is sprayed on, including the edible plants.

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 possibly harm holly but it is not labeled for this plant so we cannot recommend it for controlling/killing it. Holly shrubs would need to be treated like trees, in which case you would cut the shrubs down to stumps and then treat the fresh cuts. Crossbow Herbicide is labeled for the control of most kinds of unwanted trees. On page 5 of the label you can find directions on how to use for conventional basal bark and stump applications.
Crossbow Herbicide could harm alfafa in a hay field, especially if applied when temps are above 85 degrees.
