If the nuclear holocaust comes upon us, then what remains of the ecosystem will consist of cockroaches, bindweed, and Canadian Thistle. Really tough stuff with deep roots.

I've found that a combination of an auxin like 2,4-D and Roundup together works much better than roundup alone. Knocks it back much harder so basically only 2 applications per year, but has the risk of 2,4-D. In my experience roundup knocks them back for 6 weeks before new shoots appear.

Try hitting it at the "rosette" stage where it is just coming out of the ground about 5-6 leaves. You can broadcast spray 2,4-D with a good silicone spreader and save your grasses out there. Spring time application. Dilute gallonage - 20-30 gallons/acre equivalant. They have liquid in 1 gallon bottles here or 9 oz. soluble bags under the label "Dri-Clean, 2,4-D. This will give you a good start. Tough critter in the NE part of California in the cattle ranges.

prunfarmer...you seem new here-welcome. Just a heads up for you>> anything with 2-4-D in it shouldnt be used anywhere near the pumpkins. The chemical will kill them. The chemical, when sprayed by your nieghbor can/will gas off weeks later and move downwind and kill your pumpkins. Hoophouses sprayed with the weeds while sitting on the sidelines have killed plants a year later....just a heads up.....no 2-4-D when doing pumpkins.

I have never had problem with the Amine version hurting the pumpkins. Luck or is it special?

Glens right 2-4-D and Grazon are soil acitive. So they keep killing broad leafs for a season. But they be back in the spring, all though probablly fewer numbers. I have never used the Amine version. Round up is not soil active. So in my pastures I use Grazon, in the garden roudup and a maddox. I have to be careful getting cow manure, I always make sure it is aleast a year old or that the pasture has not been sprayed for a year.
