Mixing Weed B Gon and CCO

jrodriguez90June 14, 2010

Hey all,

I have both Weed B Gon and Chickweed/Clover/Oxalis in concentrate form. To save time I wanted to put them into my sprayer together. First, can these products be mixed? Second, at what ratio? For example if I fill my sprayer with 2 Gals do I use 2 oz of each product, or 1 oz each?

Thanks!

The two products should not be mixed. The dilution rate for Chickweed Clover and Oxalis killer should be mixed at 1 oz of product per gallon of water. The dilution rate for Ortho Weed b Gon MAX is 2 oz of product per gallon of water (for northern grass types) or 1 oz of product per gallon of water (for soouthern grass types)

The products not only CAN be mixed, but Ortho used to provide mixing instructions. But too many people didn't follow the mixing instructions, and harmed their lawns.

The mixing is a little complex, as WBG Max contains 1.5% Triclopyr already, and you're trying to mix in 8% Triclopyr to get to a proper dilution. It's easy if you're good at the math, and you shouldn't attempt it if you're not good at the math.

Those instructions are for mixing CCO with regular WBG, not WBG Max. You will be overdosing if you use those instructions for WBG Max. Triclopyr burns grass for quite a while if overdosed.

How soon can one be used after the other? I used Weed b Gone on Monday.

Oops, didn't think of that andy. Good thing it didn't damage my fescue when I did it a month or more ago. I've seen no overdosing effects, other than dead weeds.

Just to clarify: the OP was asking about WBG (not WBG Max) and CCO. These can be mixed according to the label on the CCO concentrate, which is linked above.

WBG Max was brought up in the second and subsequent posts with the warning that it already contains some of the active ingredient found in CCO.

Hmmmm - interesting. Ortho hasn't made plain old WBG for two years, and any bottles older than that HAVE the instructions for how to mix it with CCO. So why is he asking? The only product left under the original WBG brand is WBG Spot Weed Killer for St Aug Lawns...
