Rodney Steidinger:

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.
