Where can you find 60% corn meal gluten in the Oklahoma City area? If you are to reply I would appreciate it. Thank You

Deana, sorry for the slow response. Most independent garden centers in the OKC area either stock the 60% fine ground Corn Gluten or can get it quickly from their wholesaler. Try Horn Seed, Marcum’s, Precure’s or TLC or let me know what part of city you are in and I can give you other garden centers near you.

Thanks for reading the column & have a great spring.

We read your recent article regarding weed control and want to be sure we understand correctly.

It is okay to use Round-Up (w/ glyphosate) on Bermuda grass at this time since the Bermuda is dormant.

We have an area of Mondo grass, so we need to stay away from that, correct?

We’d certainly appreciate hearing back from you (and our neighbors probably would too) as we have so much henbit, etc in our yard. We’ve been using the Scott’s products for over a year and just don’t seem to be getting ahead of the problem.

Thank you so much!

Linus,

Sorry for the slow response but you understood correctly that you can currently apply glyphosate(Round-up is most widely known brand) right over your Bermuda grass lawn without damage to the Bermuda now while the grass is dormant. The glyphosate will kill any green plant tissue including henbit and other winter weeds that are currently green. Do not spray on green Mondo grass unless you want to kill the Mondo grass. Do not spray the Bermuda grass once it starts to green up unless you want to kill the Bermuda grass. Thanks for reading our column.

Have a great spring!

1. pre emergence weed control-

BARRICADE
DIMENSION

a. Where are they sold?
b. Are they available both liquid and dry?
If so, is one more effective than the other?

2. Winter grass and weed killer-

GLYPHOSATE
ROUND UP 18%
ELIMINATOR 41%

a. Which should I use?
b. Is 41% too strong?

Would appreciate your help

Thanks,
Roger

Roger,

Thanks for reading our column & your questions.

#1 Barricade(A brand name for prodiamine) & Dimension should be available at most all independent garden centers. They will generally show as ingredients, not as the name of the product. I don’t know where you live so can’t suggest actual nurseries but manufacturing companies like VPG offer these excellent herbicides in their ferti-lome line as an example. Most homeowner products are offered as a granular to spread with your spreader but a wettable powder and liquid concentrates are available if you can locate them to spray as applied by lawn care companies. Both are excellent—Dimension can be used later in season after the crabgrass or other weeds may have already started to germinate. Now is the prime time to apply.

2. Round-up & Eliminator are both brand names (and there are many other brand names now that the patent has expired) for glyphosate. If you look at the ingredients list, shop for 41% glyphosate for best results at controlling green vegetation. Most effective if the blend includes a spreader sticker/wetting agent or you add one when spraying green vegetation you want to kill. Always follow label directions.

Have a great spring!

What is a local source for Barricade Prodiamine or 60% Corn Glutten Meal here in the OKC area?
I’ve applied Round Up to kill the winter weeds in my yard and I’m row ready to apply a pre-emergent to keep the crab grass from taking over.

Thanks, Fred

Fred,

Thanks for reading the column. The Barricade name can only be used by licensed brands. Barricade is Prodiamine and that name will show on the active ingredients list in more brands. I believe K&K there in Norman stocks that herbicide in the VPG ferti-lome brand and possibly The Greenhouse. It would also be available at OKC nurseries like TLC, Precure’s, Horn Seed, Marcum’s & many other independent garden centers. All these firms can order the 60% Corn Gluten organic herbicide if they don’t have it on stock since it is still a new product with limited public demand at this point. Now is the best time to apply your pre-emergent.

Have a great spring.
