Pre-Emergent Down!

It's a little early in Pennsylvania, but the pre-emergent went down last weekend.  I use generic Barricade (prodiamine), so the pre-emergent duration is very long anyway.  At this point, I'm definitely covered into late October.  I'll add a bit more in September or so to come up to my yearly allowable amount (1.5 oz per acre equivalent) and protect the lawn and gardens through December.

Historically, I've found Barricade to be about 90% effective against the worst weeds that I want to stop--most notably, P. annua and P. trivialis.

While I was at it, six ounces per thousand square feet of whole milk went down.  It seems to enhance performance just a bit, although I wouldn't bother unless you've already had your soil tested and the soil tuned to optimum resources.

I took my soil tests some time ago.  Now I just have to send them off.  I'll get there.

I did find a few P. annua patches in the lawn, and I've since sprayed those with Tenacity (synthesized bottlebrush plant extract).  They should start dying in ten days to two weeks, although a complete kill in spring is difficult.  At the very least it'll control the issue until fall when I can get a reliable kill.

I absolutely must take lawn and garden photos for posting.  The last two warm days have accelerated things here amazingly, and the daffodils are in full bloom.
