用一次pre， 一般也就管 6-12w. 不用提早下pre。
pre是在weeds萌动之前，给个重击。主要是控制那些2,4D杀不掉的，比如，crabgrass
， bluegrass.
pre的窗口期大约1周。 之前之后都会有些漏网的。用selective herbicides控制就行。
有了clover不用急。现在clover占着地，可以抑制其他的weeds. 等到您的lawn发芽后

1.除野草。游士的帖子里没有将如何药物除掉双子叶杂草，只说他发狠一次挖掉了上千
颗蒲公英。
鉴于他也说那种对付婆婆纳的除草剂的效果不大，麻烦草神SSA大侠推荐一种除掉这些
双子叶杂草的有效的除草剂。只要除草的，不要那种weed & feed 的（记得以前有人说
过这种weed & feed其实不好）。
