<p class="MsoNormal">We have a surprising range of sprout times from Virginia up to northern PA/jersey as well as other mountainous regions, so that does not surprise me yours hasn't sprouted. Where I am in Philly it is a few inches tall already. So there
is certainly no problem waiting until yours has sprouted and then let it get a couple inches.<o:p></o:p></p>

<p class="MsoNormal">I have used a few different herbicides including glyphosate and clearcast, but have no personal preference. It takes a long time with each different one to get a preference, and I did not have that, so I have no particular recommendation.
My recommendation really was just about the strategy to start early. Mugwort can take over a field if ignored, and spraying only in the fall after it seeds has not shown me any particular usefulness. So if you hit it when it is young short, it is easy to
avoid hitting other plants, helps suppress mugwort height, and does kill a fair percent of the plants.<o:p></o:p></p>

Could you elaborate on the current stage of the mugwort your addressing. In Central PA, mugwort emergence is in the future.<br>

What material are you using?<br>

> I just wanted to say that in the past I have had success reducing mugwort invasions by spraying at this point of the year when it is still short and a lot of the natives still haven't even shown their sprouts. Now I got maybe as little as 20% killed and
the rest grew back, but that 20% was very helpful in thin areas. Also, the mugwort that did resprout grew shorter and was significantly easier to manage later in the season when I hit it again. If you have ever waded through a field of 5 ft tall mugwort
trying to spray it with a backpack sprayer, it is not easy. Anyways, just some advice.<br>
