This is Rodney with Zebra scapes
Rodney Steidinger:landscaping. I have Cole with us. He's a part of the zebra
Rodney Steidinger:scapes team, and we're glad to have you here. He's been with us
Rodney Steidinger:for a bit, and we brought him on board on the spray department,
Rodney Steidinger:just chemicals, weeds and all sorts of stuff. So we all have
Rodney Steidinger:those issues with weeds in the yard, and there's so many
Rodney Steidinger:questions that come all over the media and all this stuff that,
Rodney Steidinger:you know, chemical, and is it safe for the pets? And, you
Rodney Steidinger:know, I look at chemical, I read it, and it's like, holy cow,
Rodney Steidinger:like I'm a diet. This cans in my house to the point that,
Rodney Steidinger:obviously they sell it. So does it work? And then the effect of
Rodney Steidinger:it, how long it lasts. So I've been around chemical my entire
Rodney Steidinger:life. In the Midwest, we get all kinds of spray. My dad did
Rodney Steidinger:chemical all the time. And over time, I've learned a lot about
Rodney Steidinger:chemical and how dangerous it is, and also the huge benefit it
Rodney Steidinger:has to offer. You know, the chemical we have, and then how
Rodney Steidinger:to mix it and all that important stuff. So I have you here, you
Rodney Steidinger:seem awful young, and just want to pick your brain a little bit
Rodney Steidinger:when you go to clients and you got weeds, how can we assure the
Rodney Steidinger:customer that what we're applying and the effect of it
Rodney Steidinger:and the benefit of it?
Cole:When I usually talk to a customer, the main thing I
Cole:always stress is that we're huge into, you know, plant health
Cole:care. We're huge into making sure that their animals are
Cole:safe, that they're safe, that that we are in accordance with
Cole:the label of any chemical or herbicide that we're using. And,
Cole:yeah, I would just, I always stress safety. Safety is huge
Cole:for us. As long as you know that I always give as much
Cole:information as I can when it comes to what chemical we are
Cole:using.
Rodney Steidinger:So, I mean, you talk about it, but let's
Rodney Steidinger:talk about break it down to we're going to spray your so
Rodney Steidinger:we're going to spray your yard for pre emergent. Everybody we
Rodney Steidinger:don't pre emergent is, to me, I believe pre emergent is very
Rodney Steidinger:effective. And I kind of look at two things, is it chemical, or
Rodney Steidinger:is it and how dangerous it is. The reason why is because pre
Rodney Steidinger:emergent will not kill anything right now.
Cole:Pre emergent is a is a non selective herbicide. So it what
Cole:pre emergent does really. The basis of it is it just does not
Cole:allow any seeds to germinate if applied correctly on your soil,
Cole:any seeds of a weed will not germinate if applied Well, we
Cole:say 60% or more, but And so when you're spraying four weeds, and
Cole:you're spraying that pre emergent, it is very effective,
Cole:I mean. And you can see when you drive down streets, the yards
Cole:that have pre emergent and the yards that don't, yeah. I mean,
Cole:it's just, it's a vast difference.
Rodney Steidinger:So, and that's also critical timing,
Rodney Steidinger:yes, timing
Cole:is very critical when you're applying the herbicide.
Cole:Every herbicide is different. I mean, here at Zebra scapes, we
Cole:are licensed to, you know, to apply that chemical. So,
Cole:certified applicator. So, you know, following everything in
Cole:accordance to the label is is very important, especially me
Cole:and Johnny were both the certified spray text here we
Cole:went to school. The number one thing they stress is, the label
Cole:is the law. Yeah, the label is the law. And that's just, we
Cole:follow the label to the T and whatever the label says you're
Cole:going to get, that's the best result you're going
Rodney Steidinger:to get. So pre emergent, is it a chemical,
Rodney Steidinger:or is it not a chemical? Because it won't kill anything. It won't
Cole:kill anything. I would say it is a chemical and it is a
Cole:chemical, but when, when following the accordance of the
Cole:label, it is safe. It is very safe if you're if you're
Cole:following everything to the T and you're taking all the
Cole:precautions and the steps necessary.
Rodney Steidinger:So you, you know when clients ask me, I want
Rodney Steidinger:to spray pre emergent after you're done spraying, when can a
Rodney Steidinger:pest be outside like or should a pest be inside? Obviously you
Rodney Steidinger:want it inside when you're spraying so they mess it around
Rodney Steidinger:with you. They mess it around with you, running, running
Rodney Steidinger:around, because when it sees water, I'll chase but you're
Rodney Steidinger:done spraying, what is a safe way and what you're
Cole:not worried about at all. So the pre emergent we use,
Cole:specifically prodiamine, the label says it is safe when dry.
Cole:So that can mean a lot of different factors. I mean, it
Cole:depends on how long it takes to dry. It takes to dry, yeah, but
Cole:I always recommend two to three hours. And usually in that
Cole:period, you know, it will dry by then. But I always say, hey,
Cole:take a walk around. Look to make sure nothing's pulled up. Make
Cole:sure you're done. You know, just take those precautions. But
Cole:usually two to three hours, the chemicals dry and the dog
Unknown:is safe to go outside. But realistically, 10 minutes is
Unknown:dry, right? 10 minutes is dry, yes, but we like to be safe,
Unknown:just in case. No y'all
Rodney Steidinger:want to cover your grounds. I mean to me, you
Rodney Steidinger:spray because you're and it's dry immediately. And then, if
Rodney Steidinger:you really look into it, how much do you have to absorb to
Rodney Steidinger:affect you? Is more than they can. Yeah, it's more than they
Rodney Steidinger:can. So I do the same thing. Tell clients, hey, just. At a
Rodney Steidinger:time is to cover your basis, the amount of to absorb it, to
Rodney Steidinger:affect them. Because it's not
Cole:you need a, you need a heavy dosage. And, you know, and
Cole:again, it's, it's mixed with, with water, because, you know,
Cole:we don't want to, you can't, according to the label, you
Cole:can't just have that high of a dosage, yeah. And so you really,
Cole:you really need a high dosage to get. I mean, see something
Cole:happen right then and there. Yeah, but yeah, usually, it's
Cole:usually, like, you said, 10 minutes. It's really good to go.
Cole:But I just say, hey, two hours, two hours today.
Rodney Steidinger:No, it's good. Better be safe. And then
Rodney Steidinger:also, you give the customer reassurance, because they are,
Rodney Steidinger:like, they start questioning you 10 minutes or whatever. Yeah,
Rodney Steidinger:don't seem realistic. But, I mean, we sprayed and the dog
Rodney Steidinger:there's the effect is so minimal, or even at all, when it
Rodney Steidinger:comes to pre emergent, and that's what I was strong. So if
Rodney Steidinger:you, if you're just really don't want chemical, like, just don't
Rodney Steidinger:apply it, and you're
Cole:pre emergent, is what I would do, because that just
Cole:eliminates the tree, the weeds, at a 60 to 70% chance of
Cole:anything germinating, if you spray at the right time and
Cole:multiple times a year. I know we talked about just the climate
Cole:change and everything, and down in the valley, they're spraying
Cole:three times a year. Yeah, I know you came to me and said, Hey, I
Cole:think we need to offer three times a year. I think we I think
Cole:we do. I think three times a year is adequate. And here it's
Cole:a weed factory here in Prescott, and Prescott Valley especially.
Cole:I mean, we just have fields full of them, yeah. And so I would
Cole:definitely recommend that three times a year that application,
Cole:just because, you know, you get better coverage. Let's say you
Cole:missed a spot, or let's say it didn't sink in the soil Well, or
Cole:there was rain or runoff, or just a lot of different factors.
Cole:And I think you know, why not? Three is better than two, so
Cole:it's more than two. So why not? Yeah,
Rodney Steidinger:it is it better to be that way than all
Rodney Steidinger:you have a week. Because all it takes, like you said, the
Rodney Steidinger:weather, the moisture coming in, the winter, does it come in, and
Rodney Steidinger:the amount of money for the third spray is so minimal than
Rodney Steidinger:seeing weeds and coming out and spot spraying and all that. So
Rodney Steidinger:the factors you think about it pre emergent is, yes, it is a
Rodney Steidinger:chemical, but it's so diluted down that it won't kill
Rodney Steidinger:anything, yes. So if you're on the fence, well, spray three
Rodney Steidinger:times a year, and then that will just minimize the weeds at a
Rodney Steidinger:astronomical amount. And from then, and if the first time
Rodney Steidinger:you're spraying pre emergent, you're not gonna see great
Rodney Steidinger:effect, right?
Cole:Yeah, like we the first time you spray. Well, are you
Cole:talking about in the, you know, in the beginning parts of the
Cole:spring?
Rodney Steidinger:Yeah, yeah. Some people say, Oh, I was under
Rodney Steidinger:the impression there's a first time you ever sprayed, pre
Rodney Steidinger:emergent. You're not going to get the greatest results as you
Rodney Steidinger:did if you did, yeah, second year,
Cole:yeah. So it's, it's, honestly, it's a process of
Cole:building that just that constant spraying, and your yard almost
Cole:begins to change over time, as you see that the first time,
Cole:you're not going to see the you know, as good as you would if
Cole:you've been doing it for a year or two years.
Rodney Steidinger:Good, because if you have a broken root in the
Rodney Steidinger:ground, it won't kill it. It won't kill it.
Cole:No, you're eating a post, which is you're eating
Cole:something. You're gonna need a
Rodney Steidinger:selected kill site to kill that. Yeah, so it
Rodney Steidinger:will if the roots already established, the seed already
Rodney Steidinger:germinated, pre emergent, will not kill it, so at all, and it
Rodney Steidinger:will grow on that point of it. So now, when you come to
Rodney Steidinger:chemical like, you have weeds and you want to spray, what,
Rodney Steidinger:like, what's your safety factor of your PPE and how, how harmful
Rodney Steidinger:is this?
Cole:You know, when it comes to chemical the effects usually
Cole:don't happen till years down the road, especially if you're
Cole:constantly spraying, if you're constantly inhaling it, you
Cole:won't, you'll see the effects down, you know, 20 years down
Cole:the road. But with proper PPE, again, according to the label.
Cole:You know, that's we take, that we take those precautions. You
Cole:know, we always read the label beforehand. All right, this is
Cole:the PPE required, and we usually go above and beyond the PPE that
Cole:is required, which is, that's the only time you can, you can
Cole:go against the label as if it's better than what the label says.
Cole:Yeah. So, yeah, we, our guys are gloved and masked up, and they
Cole:have glasses and goggles, whatever they need, depending on
Cole:the type of chemical that's being used. It's just, it's,
Cole:yeah, we it's very important, very important. We don't we want
Cole:to. We want the safety of the customer, but more important, we
Cole:want the safety of the client, of the of the employee as well.
Cole:You know, down the road, we don't have breathing problems,
Cole:or, you know, I can't remember things, or, you know, something
Cole:like that. So it's very, very
Rodney Steidinger:Yeah, something you got to watch.
Rodney Steidinger:Well, number one, a customer, they spray, what one time a year
Rodney Steidinger:they're applying a year there, yeah, you know, eight hours a
Rodney Steidinger:day, constantly, day after day after day. So, yeah, it's very
Rodney Steidinger:important to have all the mask on. So how critical is for a
Rodney Steidinger:client to say, get the dog inside, close the windows up.
Rodney Steidinger:You know, I'm leaving, like, where's the caution? Where?
Rodney Steidinger:Like, hey, it's safe. Just a spray, and we'll go on. What's
Rodney Steidinger:your thoughts on that stop interrupted right now,
Cole:when I, when I first walk up to a client's house, the
Cole:first thing I do is always ask, Do you have pets? Do you have
Cole:dogs? Do you have any. Sort of animal that likes to roam around
Cole:on your property, because if, and if it's yours, please keep
Cole:it inside. Keep those windows shut. Yeah, just, just like
Cole:you're saying, we just, I, oh, that's the first thing I do is
Cole:when I walk, is keep the window shut extremely is that, I don't
Cole:want you know if there's a drift coming in with with the wind,
Cole:and you're drinking your tea, or, I don't know your maybe your
Cole:coffee, whatever you like, whatever you prefer. You know,
Cole:some chemical gets in that tea or something. You know it
Unknown:affects you at all.
Cole:Um, no, not really. It's such a small dosage, it won't
Cole:but again, we're very we want to keep things safe. No,
Rodney Steidinger:I want. I want. I'm just challenging you.
Rodney Steidinger:We want to be 100% always challenging me. Oh, but overall,
Rodney Steidinger:that small amount of chemical will not affect Yeah, because
Rodney Steidinger:you're diluted down and you spray the moisture. But still,
Rodney Steidinger:it's a safety factor. It's not only a factor. It's just knowing
Rodney Steidinger:the thought you have chemical on you, which I would strongly
Rodney Steidinger:recommend. Yeah, that being closed and the windows being
Rodney Steidinger:closed around it, because the drift is the issue.
Cole:The drift is the wind pickup. The wind pickup just
Cole:that coming through the windows. You don't want to be breathing
Cole:that in. But again, it's such a small doses that it would take.
Cole:It would take years of just breathing in every day, and
Cole:then, you know, maybe down the road, like respiratory problems.
Cole:But for a client, I would say, the precautions we take and the
Cole:chemical you we use, you're you're in good hands, and you're
Cole:very safe. When we're applying it out
Rodney Steidinger:yard, you spray weeds. They have pets,
Rodney Steidinger:when's a good time to let them out with post emergent.
Cole:Post emergent depends on the post you're using. But
Cole:again, the label says, when it's dry, it's safe. The one we use,
Cole:same thing, when it is dry, it's safe for the pets. So whenever
Cole:dry is, you know, but I always
Unknown:Yeah, in Arizona, minutes, but let's say two to
Unknown:three
Unknown:hours, two to three hours just to be safe, yeah? Well, that's
Rodney Steidinger:great insight. And then, you know, a
Rodney Steidinger:lot of people are 100% get a chemical, and I understand, and
Rodney Steidinger:that's why I still say really think about pre emergent if you
Rodney Steidinger:are 100% chemical. Percent chemical, because overall it is
Rodney Steidinger:such a light dose of chemical compared post emergent. Post
Rodney Steidinger:emergent is still very safe with everything happening. You know,
Rodney Steidinger:you put the PPE on and all that stuff is critical. And a lot of
Rodney Steidinger:I learned over the years post emergent and pre emergent,
Rodney Steidinger:believe it or not, they get immune, right?
Cole:Yeah, the soil can get like, it's strange. The soil
Cole:almost builds up resistance or immunity over over time. And so
Cole:we work in it's called IPM, integrated pest management.
Cole:You're always reevaluating and seeing, okay, maybe we need to
Cole:make some changes here. Maybe the soils, you know, it's built
Cole:up a resistance over, I know, maybe a course of three to four
Cole:years, and it's no longer working. We might need to switch
Cole:herbicides, you know. So, yeah, I would say if, if you've been
Cole:doing it for a while, you're noticing, wait, it's not given
Cole:the effect that it was in the beginning, you know that that
Cole:could be, that could, you know, maybe, mean, we just, you need
Cole:to switch chemicals, or, you know, a variety of different
Cole:things. But yeah, the soil can definitely build nothing meaning
Rodney Steidinger:towards it. What's the how many years are
Rodney Steidinger:you talking or applications, I say,
Cole:from what I've seen and from what Johnny has seen, or
Cole:other spray tech is it lasts for anywhere from three to five
Cole:years, and then you start noticing a slight decline, yep,
Cole:a slight decline, but three to five year period, I mean, it's
Cole:golden, yeah. So yeah,
Rodney Steidinger:yeah, that's, that's, that's what we do. I
Rodney Steidinger:mean, we, you know, we'll look back when someone says, Hey,
Rodney Steidinger:we're not seeing the effect. And usually we like, Wait, when did
Rodney Steidinger:we switch that chemical over? We'll go back then right away,
Rodney Steidinger:hey, switch it over. Like you said, we just added the
Rodney Steidinger:chemical. We mix it up a tiny bit or a lot, and then we go
Rodney Steidinger:back and, you know, rotate three different ways and talk to our
Rodney Steidinger:our rep on what we should offer for that chemical. But Cole was
Rodney Steidinger:great having you a lot of insight. This is valuable
Rodney Steidinger:information for safety and also for pest as weeds and everything
Rodney Steidinger:that happens around our yard, and to keep them at a minimal as
Rodney Steidinger:possible, and, number one, as safe as possible. And that's
Rodney Steidinger:important, but also the confidence that a client is
Rodney Steidinger:confident that they're safe and they're going to get the
Rodney Steidinger:results. Because you see something being sprayed, it's
Rodney Steidinger:like, is this going to work? And all those things go through your
Rodney Steidinger:mind. So it takes a lot of education, a lot of classes that
Rodney Steidinger:you take. How often do you take these classes? Throughout the
Cole:year, throughout the year, I always, there's not really a
Cole:class I take, but I always touch up on things. I'm always
Cole:rereading my labels where you're looking at, you know, the test,
Cole:practice tests and then, but usually you renew your CEUs once
Cole:a once a year,
Unknown:yeah? So yeah, every year you have
Cole:to. You have to, because something changes like that. But
Cole:by law, yeah, by law, yeah,
Rodney Steidinger:for us to have our license and be able to
Rodney Steidinger:spray, that's all critical information, yeah? But anyway,
Rodney Steidinger:thanks for having you. Is pleasure, and we hope this is
Rodney Steidinger:better, very beneficial. And put your comments below if you have
Rodney Steidinger:any questions or any just to. Agreements, thanks.
