How To Use A Weed Killer for St Augustine Grass
The label is the law, especially with herbicides, so you need to follow the mixing directions on the label exactly as they’re written. Most yard spraying is done from either a backpack or a tank, which means you’ll do the mixing in the tank or backpack.
Once it’s mixed, start spraying at the foundation of the house and work your way outward in a spiral pattern. If you’re spraying a field, a back-and-forth pattern will work.
提示：无论您使用哪种，始终将除草剂带的带束一两英寸重叠。
Are Weed Killers for St Augustine Grass Safe Around My Pets And Children?
No. Herbicides typically have toxic ingredients that are safe in small amounts but becoming increasingly dangerous as the exposure mounts.
小孩和宠物尤其敏感to toxins. Keep them away from the area being treated until it is completely dry or the dust has settled.
警告
Weed killers are not safe for use around your pets or children. Please exercise caution when using any of these products.
