All right, Mr. D. Let’s talk about systemic
insecticides. Real popular now, these days, a lot of people are usin’ ’em. Some folks
are not usin’ ’em. So, let’s talk about ’em. – They’re just a, they’re another tool, there.
In my opinion they’re a very useful tool. – [Chris] Yeah. – Systemic insecticides are highly soluble
in water so the plants can take them up through their vascular tissue and it enables you to
be able to treat extremely large trees that you can’t spray. – [Chris] Mm-hmm. – It also is very selective about the insects
that it kills. You don’t broadcast it out there so it’s not killin’ a lot of different
insects. – [Chris] Right. – It’s killing primarily the insects that
suck sap. – [Chris] Mm-hmm. – And aphids and scale insects. – [Chris] Okay. – It’s really good on those types of insects.
When you’re in a situation like that and that’s what you need, then I don’t think you can
go wrong by using systemics. Many of ’em you could, will only take, you’ll only need one
treatment a year. – [Chris] Right. – To break the lifecycle. But they’ve been
around for a long time. Some of them are more toxic. Have higher mammalian toxicity than
others. And so, as with any pesticide, be sure that you follow, read very carefully
and follow the label instructions when applying these products. Some of them, the mammalian
toxicity is not any worse– – [Chris] Mmm. – Than some of the other pesticides. But they’re
a very, very useful tool. I believe in using technology and systemic insecticides are a
product of research, you know, years and years of research and technology and I believe in
using it. And the University of Tennessee also agrees with me. – [Chris] Yes. – As do other research based universities
and institutions. – Widely recommended. Widely recommended. – [Mike] Very, very widely recommended. – Now, what are some of those systemic insecticides? – Imidacloprid is one. – [Chris] Mm-hmm. – I’ve got a list of them here. Let me make
sure. – And that’s probably one that most folks
would know. – Right. – And Joellen, you’re probably familiar with
a lot of these as well, right? – Some, yes. – Mm-hmm. – [Mike] And some of the more common ones
is Orthene, Acephate has systemic activity. – [Chris] Mm-hmm. – [Mike] Imidacloprid, Merit, and Safari– – [Chris] Mm-hmm. – [Mike] Are some of the more common products
that are out there, insecticides that are out there. The active ingredient in Safari
is, what? – [Chris] Dinotefuran. – [Mike] You said that real good. Yeah, uh-huh. – [Chris] Familiar with it. – [Mike] And Imidacloprid, Bayer’s Tree and
Shrub insect control. And Merit is also Imidacloprid, also. – [Chris] Yeah. – And then Orthene. I still think Orthene
or Acephate does most of its killing by stink so bad, smells so bad I think they just die. – [Chris] Yeah, that stuff is horrible! – [Joellen] Yes. – [Chris] It does, it smells bad. – Really bad, has a bad smell to it. – Now, can we explain again to the homeowners
how do these products work, again? – The way they work is you put them on the
ground, you’ll mix them with water according to the label directions. Spray, or are there
are any, do you know of any granulars? – There are. – [Mike] There are some granulars? – There are some. – So, the granular ones you do a little sprinkle
on the ground, according to the label direction, under the plant. When it rains or when you
water it they are readily water soluble, so they dissolve in water and the roots then
take the product up and it goes through the vascular system and then it’s in the sap. – [Chris] Mm-hmm. – [Mike] And insecticide is in the sap of
the plant and, and… You know, you’re good. The things you need to be careful about using
these under, and again, it’s not gonna be on the label, but if you’re usin’ the tree
fruits and tree nuts that we eat– – [Chris] Yeah, sure, right, right. – You know, you wouldn’t want to do that.
There are some products within the commercial pecan industry, systemics that are labeled
for use in pecans. However, you want, they’ll tell you not to use that product after April,
I mean August 1st or something like that, and that way, because of that that product
is completely gone by harvest time. You’ve got a harvest goal on those pecan products.
But, again, be careful if you have fruit trees– – [Chris] Mm-hmm. – And fruit plants around where you’re putting
these products, you need to be very careful with that. But they work really well. The
plant takes it up. You need to make sure that if it’s raining, if you’ve got a rain event,
are getting plenty of rain, then you don’t have to do a lot of watering. But if you put
it out there and it’s not, you’re not getting any rain, then you do need to irrigate, you’d
need to water it, then. Sure. – [Chris] Right. – But the label will tell you that. – Yeah, the label will tell you that. – The label will tell ya. – Definitely do that. And the Bayer product
comes in a liquid or granulated form. – Both ways. – Both ways. – Yeah. – And I’ve actually used both. – Either one works. – They work. – Either one works. – Well, and since we’re talkin’ about systemics,
are there any systemic fungicides that you may know about? – Some of the newer fungicides have some systemic
activity and we used to say always, ’cause as a young extension agent we learned that
fungicides were prevented in nature. – [Chris] Yeah, yeah, that’s right. – Protected treatment and you had to have
it out there. When the spore landed on the plant it had to land on some fungicide and
die and if you didn’t have that it wouldn’t work. But some of the newer fungicides out
there do have some kickback activity, some systemic activity. It’ll move, some of them
only move within the leaf. – [Chris] Mmm. – They won’t move within the total plant.
But they may move from one part of the leaf to the other– – [Chris] Mm-hmm. – Within the leaf surface. It’s not as systemic
as insecticides and herbicides. – [Chris] Right. – Not at that point, yet, but there is some
kickback activity in some of the newer fungicides. – Okay. I wonder if any of those are available
to homeowners? – They are. – Yeah, the systemic fungicides? – I don’t know. – I think some of them. – I think some. – Some of the, and I’m not gonna mention trade
names. – [Chris] Yeah. – But, first on my mind, but I think some
of the new ones have a little bit of kickback activity. Just, if it says that it has some
kickback activity, that means it’s systemic. Some systemic activity. – Okay. And you’re familiar with those products,
too, I’m sure, aren’t you? – Yeah, but, like him, I have the commercial
ones and I used to use that in the flower beds. – [Chris] Right, yeah. – And they would, you know, it took just a
very little bit, but it made a big difference. – [Chris] Okay. – It really, they did work. – And I guess, too, using the fungicides,
I mean, you don’t have to worry about beneficials or anything like that, right, ’cause– – Right. – It’s not gonna do any harm to ’em. – No. – They don’t have any– – Yeah, no activity on ’em. – Pretty safe. – Yeah. – You don’t have to worry about killin’ beneficial
insects. – [Chris] Right. – [Joellen] No. – With the fungicides.
