Weedmaster would not injure tolerant grass unless the product was over applied, applied at time when temperatures were over 90 degrees or if it was applied at a time the sun was directly over your yard.
Weedmaster is not labeled for use in residential lawns therefore would not recommended for weed control as injury could occur.
Weedmaster should not be applied by aerial application when sensitive crops are growing in the vicinity. Please refer to page 4 of the product label where Wind Speed, Susceptible Plants and Equipment are discussed.
Weedmaster – while not specifically labeled to kill ginger plants – likely would harm them due to the plants being similar in nature to other broadleaf weeds the product targets. If you need to kill grassy weeds safely in areas you have ginger planted, you could use a product like Grass Out Max. However if you have broadleaf weeds you likely would need to hand pull or carefully spot treat them to remove them from the ginger area.
Weedmaster should not harm bees when used as directed and they are not sprayed directly. We would recommend applying early morning when they are less active to limit exposure.
Weedmaster is not labeled to control Hawkweed. Unfortunately we do not carry any Range and Pasture selective herbicide to control Hawkweed therefore we would recommend contacting the Local Dept of Agricultural or Cooperative Extension for recommendations on treatment advice in your area.
Weedmaster should be used within 24 hours of mixing with water.
If you are just spot treating with Weedmaster herbicide, then you can use 1 oz per gallon of water in a hand pump or backpack sprayer. For broadcast applications, you will use 1.5 - 4 pints of Weedmaster in 5-40 gallons of water per Acre, depending on the stage and density of the weeds you are treating. There is a full table on the product label. So for larger areas, you will need to calibrate your sprayer to determine how much area you cover per tank.
Unfortunately, Weedmaster is not labeled to help control coffeeweed. Instead, you can use Nufarm Weedar 64, which is labeled to help control coffeeweed and it can be used at a rate of 1/4 to 3 pints per acre. Please read the product label for complete application instructions.
