How to apply Barricade (Resolute 65WG)

amoncurAugust 8, 2014

I purchased the generic form of Barricade (Resolute 65WG) and am not 100% clear on their instructions for application. It comes in granular form, and indicates the granules should be mixed in a spray tank, but also indicates that the product has low solubility in water. How is it going to dissolve in the spray tank if solubility is low, as it also states that the granules must be mixed thoroughly in the spray tank? Or is it not supposed to completely dissolve?

Here is the label: http://www.doyourownpestcontrol.com/SPEC/LABELS/resolute65wg_label.pdf

When they say to agitate the tank (with product already added), are they saying "shake it really hard"? Is that what is meant by "agitate"?

What is a "carrier" (mentioned in their mixing instructions)? Is that the water I use to mix the product in?

I am in Arizona and will be overseeding in mid October with perennial ryegrass. For the application of Resolute, I will only be mixing with water, no other herbicides. My yard is ~1400 sq ft.

Here is a link that might be useful: Link to Resolute Label

While low, it's high enough that a few tablespoons per gallon can dissolve with no issues. I use pretty much the same stuff and it dissolves easily.

Low solubility generally means that there's a limited weight of material that will dissolve per gram of water.

>>What is a "carrier" (mentioned in their mixing instructions)? Is that the water I use to mix the product in?

In this case, yes--it's the water.

In general, a carrier is whatever you're using to evenly distribute and spread a given product.

>>When they say to agitate the tank (with product already added), are they saying "shake it really hard"? Is that what is meant by "agitate"?

Pretty much. I don't shake mine, I put the granules in, then use the hose to mix it as I'm adding water. A little extra mixing is usually required after the sprayer is full.

Thank you so much! Very helpful!

In the label section "Poa annua
Control in Established Bermudagrass Overseeded with Perennial Ryegrass (Arizona,
California, Nevada and Texas Only)" it states to use .58 - 1.0 lb/acre of product. My lawn is ~1400 sq ft, which is 0.032 acres. So, I should be using .019 - .032 lb of product (0.3 - 0.5 oz). That's hardly anything - is that correct?

Sounds right.

If it helps, on my ten thousand square feet (seven times your size), I use a grand total of 15 tablespoons per year.

Which is practically nothing compared to that huge jug. :-)

Keep in mind I think Barricade does stop rye from sprouting, but I could be wrong on that. Check to make sure it either doesn't stop rye, or that the amounts you're using are low enough to wear off before seeding. A 2 month shield doesn't involve very much product at all--I tend to target an 8 to 9 month shield.

Thanks, page 8 has a section specially labeled "Poa annua
Control in Established Bermudagrass Overseeded with Perennial Ryegrass (Arizona,
California, Nevada and Texas Only)" and indicates the amount above...seems pretty specific to my situation so I hope the rye comes in nicely. Unless I'm missing something in the indications?

Overseeded with perennial rye in this case means already established. Above, you mentioned you were going to overseed in October.

Pre-emergents only work on sprouting seeds, they're not herbicides and won't kill established plants.

So here, I'm not really sure what they mean.
