How Lawn Pre Emergents Work

Let's start by taking a look at how pre-emergent formulas like Barricade herbicide help prevent weeds from showing up in your lawn.Herbicides in general use a variety of different mechanisms to stop weeds from growing, but pre-emergent herbicides specifically prevent growth after germination in the weed seed by inhibiting a particular vital enzyme in the seed. Because of this mode of action, it only keeps seeds from sprouting and does not control weeds that have already sprouted, requiring it to be used during very specific times during the growing season. It also means that it won't workin a lawn that has been freshly seeded, or rather that it will work to keep the weeds away but will also keep your lawn seed from sprouting.

Safety First!

When it comes to applying any type of pesticides, even herbicides, you must pay close attention to safety. As an example of what not to do, a local college greenhouse had been advised to mix a couple insecticides together for a particular problem in the greenhouse; both student workers who applied the insecticide had trouble breathing following the application and had to stay home for several days, a reaction that could have had far reaching health and legal consequences for the student workers, the university and the supply company that recommended mixing the products. Another example is testing done on inert products in glyphosate, or RoundUp, which had been considered a fairly safe for general use based on tests of the glyphosate. The study found that an inert ingredient essentially smothered human cells, killing them, including embryonic, placental and umbilical cells, causing miscarriage.

By doing something as simple as checking the warnings on the Barricade herbicide label, you will be able to find the information needed to safely apply the herbicide. One of the first things to look at is what personal protective equipment (PPE) you'll need before applying it. This information is on one of the first few pages of the label. For Barricade, you'll want a shirt with long sleeves, long pants, socks, shoes and protective gloves. A commonly used glove are nitrile exam gloves, available in the first aid section of most drug stores or major multi-department chain stores such as Wal-Mart or Target. Nitrile is by nature resistant to chemicals that can otherwise cause skin injuries or can be absorbed into the skin.

When you're done for the day or the season, it's very important to store herbicides safely. Keeping them where children cannot get to them whether it is in a locked cabinet or building, labeling and securely closing mix bottles to help ensure limited accidental exposure and makes it much easier to dispose of it properly.

Application

There are many tips and tricks you can pick up to make herbicide application go faster and more safely. Whether you're spraying a liquid or dispersing granules of Barricade, you'll want to wait for a relatively calm day. If you live in a high wind area, starting on the downwind side of your property and working your way upwind will help keep the herbicide blowing away from you. If you do have to apply in a breeze or wind, be very careful to control overspray onto a neighbor's property.  You do not want to get the pre emergent spray on landscaping that can't handle the application, so be careful!

Spring applications, which control summer weeds, should take place after air temperatures reach 65-70 degrees F during the day for four days in a row. Fall applications, which control winter weeds, need to wait until night air temperatures reach a low of 55-60 degrees for four days in a row. Figure out how many square feet you'll need to treat and then use that figure to determine howmuch Barricade to mix or distribute. You can find this figure on the label, usually in terms of how much to mix or distribute per 1,000 square feet or per acre (43,560 square feet).

Combined Products

Combined products are those that contain not only Barricade herbicide but also an additional lawn care product. One of the most popularare weed and feed products, which include a fertilizer component. These types of products can help save you time by requiring a single application rather than one of each product. Fertilizer mix products should not be applied on southern lawns or warm season grasses, as the fertilizer will burn the desired grass seedlings, causing significant damage to your lawn.

It is very important that you not try to mix your own combination solutions without consulting a landscaping professional. Much like the college greenhouse example above, mixing products without knowing exactly what they will combine into can create a significant health threat. If you want to know what has been tried safely in your area, try contacting your county extension office run by your state's land grant university.

Advantages Over Other Herbicides

Barricade has a low odor and forms a clear liquid, providing an esthetic advantage which is unlike many other herbicides that very often cast a yellow tone to areas that have been treated. Because it is relatively concentrated and does not take much to get the desired effect, it can be applied using a very low dosage. It is a relatively safeherbicide, and is not restricted in terms of who may use it and whether training, a certificate or a license is needed. Compared to other herbicide classes, pre-emergent herbicides help prevent work by keeping weeds from sprouting in the first place. It is very stable in solution, keeping it from settling out.

Now that you've had a chance to educate yourself about the basics of Barricade pre-emergent herbicide, you can start thinking about where and how to apply it to prevent weeds from popping up. By providing a good quality pre-emergent herbicide such as Barricade, you'll be able to enjoy your lawn more and weed it less.

Mark,

I live in NJ and my lawn service put this product down today along with fertilizer. Is it ok for me to throw down seed and topsoil over the next 7 days. I need to cover up many bare areas.

Thanks

    Hey Alan,

    I would give it about 2 weeks. Most manufacturers say 30 days, but in my experience, 2 weeks is enough.

Mark,

I live in Central Oklahoma and have a bad Poa Annua problem. I am going to use Barricade granules this fall to try and control it. The local paper says it is time to apply pre-emergent but according to your article I should wait until the night time temp is between 55 – 60 degrees four days in a row, which might not occur for another month. Does that advice apply to me? Also, how long does Barricade granules stay active?

Thanks

Mark – I have a yard full of Kentucky bluegrass which I want to get rid of. I have heard that Barricade is a great pre-emergence for Kentucky bluegrass, poa anna, etc. A couple of questions:
1. I’m not sure if my bluegrass is an annual or a perennial. Since this is the second year that it has germinated I’m guessing its a perennial. Will a good application of Barricade in late August prevent the bluegrass from germinating every year or will I need to use Barricate every August?
2. How many applications of Barricate this August do you recommend, i.e. a pre-emergence in August and a later application maybe in late September???
3. Also, I’ve struggled to find the right fescue grass seed for my yard. I’ve tried (1) Titan RX, (2) blend of 3 northern fescue seeds, (3) creeping red fescue, (4) Kentucky 31 fescue, etc. I have several shade trees in my yard which make growing fescue a challenge, but I have had some success. Do you have a recommendation of a good fescue seed? I live in the northwest part of South Carolina (Anderson, SC).

Thanks, Bill

Hi Mark – a lawn maintenance company sprayed pre-emergent/Barricade without my knowlege (or consent) on my lawn this afternoon, the grass is young (sod was laid 2 months ago). Is there anything I can do to minimize its negative impact on my young lawn? Thanks!

    If it’s sod, it will probably be ok…as most sod should be able to handle the Barricade since it’s typically “older” grass. I would just make sure to water it more than usually if possible.

Hi Mark,

I have a 2000 square feet lawn and was going to buy a 0-0-7 Pre-emergent from Sunniland (covers 20000 sq feet). Can I buy this product and store it for years in an air-tight container? I am not sure if shelf-life is an issue. Any thoughts?

Thank you!

    Yep, keep it airtight and you’ll be fine. I’ve never heard of it expiring if its stored properly.
