Spectracide UNITED INDUSTRIES CORPORATION Weed Killer,40oz

Works perfectly.

this is pre-emergent safe for grass - it goes on before the weed comes up. it doesn't do great job "killing weeds", but does kill some (others temporarily receed) nothing kills noxious weeds even surface sprayed grass killer will not, that's why their called noxious it is best done with a hose so the solution reaches the root (also it can kill some weeds already up better that way) if you have left over from last year it still works scotts weed and feed (great product to prevent grabgrass - but also not perfect) should also be used

The spectracide weed killer concentrate is quite effective. This season, for some odd reason had helped in growth of crab grass extensively, so in no time crab grass flourished all over the neighborhood. I had used this product several times since last year and it was keeping weeds from over growing, but then all of a sudden since my last treatment, the growth of crab grass occurred, and I think because a day or two after its use, rains came and washed it away, or probably saturated its effects. I usually use a spray with my water hose and spray on, it's easy and quick. But I may be wrong but do not have the time or energy to spray with a bottle.

I still have my dad's vintage glass bottle from the 1950s to dilute the concentrate. This product has been effective with near total weed eradication after only three years at a new residence. It was a 'weedy' nightmare to begin. Thank you!

I can't tell you whether it works or not yet, but the dilution instructions are ridiculously complex. Requires you to know exactly what weeds you have, and your lawn type. You have to be both a botanist and a chemist to get it right. In the end, it's much easier to use a pre-mixed solution than this. I wish I hadn't bought this.
