Per the GrazonNext HL Herbicide product label for Seeding grasses:
Preemergence: Grasses may be reseeded in the fall following an application of GrazonNext HL applied in the spring or early summer.
Postemergence: During the season of establishment, GrazonNext HL should be applied only after perennial grasses are well established (have developed a good secondary root system and show good vigor). Most perennial grasses are tolerant to GrazonNext HL at this stage of development.
GrazonNext HL Herbicide is applied at 19-34 fl oz per acre per annual growing season for bullnettle. The label recommends to use 3 gallons of water every 1000 sq. ft., which would equal 130 gallons of water for each acre.
GrazonNext HL Herbicide is only labeled for use in the following locations: Range-land, Permanent Grass Pastures, Conservation Reserve Program (CRP) acres and Wildlife Management areas. It should not be applied by a lake as it is toxic to aquatic invertebrates and may be toxic to fish. Drift or runoff may adversely affect aquatic invertebrates and nontarget plants. You could use a product like Rodeo Herbicide as it is labeled for use in and around ponds, streams, lakes and other bodies of water including bodies of water that are located in wildlife habitats.
In order to know how much GrazonNext HL Herbicide to use, then you need to know how much area your 200 gallon sprayer covers. It is most important to use the correct amount of product and consider the water a carrier. For ragweed, for instance, you would use 1.2 to 1.5 pints (19 to 24 fluid oz) product per acre using a minimum of 10 gallons of water per Acre.
No, GrazonNext HL Herbicide is not labeled for crabgrass. We carry a full line of products for crabgrass control that can be found here.
GrazonNext HL Herbicide is a post-emergent herbicide so it can be used any time the weeds are in an actively growing state.
While GrazonNext HL Herbicide is not labeled to treat for burweed, there are several university articles that state 2, 4-D is a great active ingredient to treat for burweed. You could also use a product like Dismiss Turf Herbicide which is labeled for burweed, and can be used in warm and cool season grasses.
Per the product label for GrazonNext HL Herbicide
Preemergence: Grasses may be reseeded in the fall following an application of GrazonNext HL applied in the spring or early summer.
Postemergence: During the season of establishment, GrazonNext HL should be applied only after perennial grasses are well established (have developed a good secondary root system and show good vigor). Most perennial grasses are tolerant to GrazonNext HL at this stage of development. GrazonNext HL may suppress certain established grasses, such as smooth bromegrass (Bromus inermis), especially when plants are stressed by adverse environmental conditions. Plants should recover from this transient suppression with the onset of environmental conditions favorable to grass growth and upon release from weed competition
GrazonNext HL Herbicide will kill sweet and white clover as well as horsenettle. It would not selectively kill the nettle and not the clover.
Unfortunately the GrazonNext HL Herbicide is not labeled to get rid of chamberbitter. If you need a pre or post-emergent herbicide, please let us know what type of turfgrass you have and how much area you are treating so that we can make an appropriate recommendation for you.
As long as you apply on a non windy day to limit drift of GrazonNext HL Herbicide and do not spray the corn directly or allow overspray to contact it, there should not be an issue applying to the fenceline around a corn field.
GrazonNext HL Herbicide would be best applied during the day, (ie in the morning) so that it has time to dry. This will prevent any issues that can occur such as disease that can thrive in moist conditions when you apply at night and it does not have time to dry properly.
GrazonNext should only be used on pastures and other areas approved on the product label, not on residential lawns.
GrazonNext HL Herbicide is labeled for use in pastures. Animals should be out of the area during treatment until dry, typically 4-6 hours.

GrazonNext HL Herbicide is not labeled to control baby's breath (Gypsophila paniculata), specifically. However, the label does list annual common chickweed, which is in the same family (Caryophyllaceae). This Extension article has more details about mechanical control and suggestions for chemical control, which does include 2,4-D as a recommendation. You could also use a non-selective herbicide like Gly-Pho-Sel Pro to spot treat this plant.
If you are asking about using compost that may have GrazonNext residual in it, per the product label: Do not use hay or straw from areas treated with GrazonNext HL within the preceding 18 months or manure from animals feeding on hay treated with GrazonNext HL in compost...Do not use manure from animals that have grazed forage or eaten hay harvested from treated areas within the previous 3 days, in compost, mulch, or mushroom spawn.
So even if it has been 18 months since hay was treated and fed to the animals, you would still need to wait at least 3 days to use the manure in compost or mulch.
GrazonNext HL Herbicide is not labeled to be used in residential lawns. There are different factors involved that would determine how damaged your St. Augustine turf would be after application and if there is any chance at recovery.

GrazonNext HL Herbicide is applied at 1.5 to 2.1 pints (24 to 34 fluid oz) product per acre for buttercups.
