    I've got several patches of Common Knotweed and Japanese Clover in my yard and was wondering what selective herbicide would work best for taking them out? Thanks!

    UAP's "Chaser" (ester) wipes 'em out in one shot. The regular "weed-b-gone" stuff ain't gunna do much.

    A chemical will knock out knotweed but usually won't fix the problem entirely. When knotweed is present that means you have poor soil conditions.

    what is 'prostate knotweed'?

    Would this require a prostate exam to diagnose??:)
