感觉你那现在用可能晚了，这个是要天气刚刚开始暖和就用上的。 |

谢谢，我刚才也搜到那个网页。我拖拖拉拉现在还没买割草机，周末一定要弄了。

directed. Make sure you add some kind of surfactant like this one:

Or if that's too troublesome to get, just add a few ounces of liquid soap as
a homemade surfactant per gallon of solution.
As always, read and follow the labels carefully.

"Or if that's too troublesome to get, just add a few drops (say 1-2
teaspoons or 5-10 ml) of plain non-antibacterial liquid soap or dish soap as
a homemade surfactant for each gallon of solution."
I got the quantity of liquid soap per gallon wrong.
The active ingredient is "quinclorac" for post-emergent crabgrass control.
So if you can find any product with quniclorac as the active ingredient, you
should have a chance. Make sure the product works with your grass type.
For next year, remember that pre-emergent control (kill before crabgrass
emerge from soil) is much more effective than post-emergent control (kill
after crabgrass emerge from soil). |
