Using Roundup

[Boondox]

We're facing an invasion of burdoc (sp?) on our hills. It's a tough invader, about six feet tall on a single trunk often over an inch in diameter at the base. The leaves are huge, and the seed pods are spiky ping-pong ball sized things that get caught in my dogs' fur so tightly they have to be cut out. I tried cutting the seed pods off before they matured, but the plant just sends out twice as many.

Can I use Roundup on a weed this big? If so, do I have to drench the entire plant or..?

I doubt that Roundup will kill it with one application. I would suggest Crossbow.

Roundup is tricky to use, but it works well if you do it right. There are many dilutions available to the consumer and it is easy to buy the wrong stuff. Some is already diluted and is very expensive, but it appears to be cheaper than the super concentrate. If you only want to spray a dandilion in the driveway, I suppose "ready to use" it is the way to go. Better to spend the bucks on the super concentrate and mix what you need if you want to do a large area or fenceline. It works best if you spray early in the spring when plants are small, young and actively growing. I mix a cup of sudsy ammonia to 4 gallons of water, (the young plants are hungry for nitrogen and it gives the Roundup extra punch) I hear that adding diesel fuel also helps but I have not tried it yet. As the plants mature, and growth slows down, the Roundup is less effective. Roundup, used by itself, without nitrogen or a sticker-spreader of somekind, on mature plants, is not very effective. There are lots of herbicides available, it is wise to know how they work and what the drawbacks are, especially in a garden area.

I would try it - Roundup is by far the most widely used herbicide in these parts because of its effectiveness on a wide variety of weeds. It can be supplemented with other herbicides (such as Goal) to further broaden its spectrum. As Treeboone says, I would get super concentrate (41%). You no longer need to add sticker -spreader as Roundup now already contains it. Apply just to the point of runoff. This time of the year, I mix 3oz./gal. Earlier in the year, 2oz. is enough. You may want to invest in a backpack sprayer (very handy), or a 14 gal. Shurflo electric stapped onto the hood of your tractor.
Gempler's has some good books on weeds and weed control as well as spraying equipment.

Round up just put out a new product for brush and other hever plants maybe it would work better for you.Just called the wife she just used some.She said it even says in the distructions that on thick stemed plants you may have to apply it twice...Good luck...
