View Full Version : Merit Insecticide Question

I spread a 14 pound bag of Bayer Merit granulated on my yard last night, and
watered the lawn afterward with between 0.25 and 0.5 inches of water to wash
it in. I'm attempting to kill Japanese beetle grubs - have had a bad
problem for the last tow years. I applied the Merit at a heavier rate than
recommended. The recommended rate is 2.8 lbs/1000, I used 3.8 lbs/1000. My
soil is clay and perculates a little slow.
Tonight we had a heavy thunderstorm and heavy rain. We got about 1 inch of
rain in about 15 minutes.
My question is; did all of my Merit wash away? Should I reapply?
Thanks

It doesn't matter. The grubs have become Japanese beetles and are
flying around now. Reapply before July 4 next year.

Heh, what do you think those beetles are doing when they're not
feeding?... That's right, laying eggs for the next generation.
The Merit will protect Peter's lawn from grub damage this fall
and consequently next spring too.
I really doubt it has washed away, Peter. It clings to organic
material real well.

Thanks for you reply Steveo.
Will it hurt my lawn to reapply? I *really* need to wack the grubs bad.
They got me the last two years before I realized what was going on. I want
the mothers dead.

Here in Ontario you are not permitted to reapply. Merit has a very long
residual... and you have already admitted to applying above the recommended
application rate. You should leave it alone.
Keep in mind that the application will not do anything about the existing
grubs in your lawn. Merit will only prevent a new infestation. I have
applied it many times and have seen it watered in, not watered in and
drenched. It has still been effective in preventing a new infestation every
time.

Fasinating. How does it prevent the new grubs from feeding? Why is it
prohibited to reapply Merit twice in one year? What is the harm in it?

I can't tell you the science behind it, but do know that that is how it
works. You are not permitted to reapply because it has such a long residual.
When I used to spray Dursban and Diazinon and had spraymix left over the
next day I would just count it as water. The 1/2 life on that stuff is very
short, depending upon water ph, sunlight exposure etc. Merit is different.
It hangs in there.

It takes their appetite away, big grubs can live off of their body
fat -much- longer than small grubs.
The small grubs starve..the big ones start eating again.

Thanks Peter -
But why won't it do anything for existing grubs? I read that it kills
grubs. Also, the new infestation is under way, the beetle population peaked
last week and the eggs shouls start hatching grubs any day now. What I
understand, now is the best time to apply Merit.
I also understand Merit is not harmful to people and pets, so
overapplication doesn't have any *real* adverse effects.

Merit has a very long residual. It hangs around for about 3 months. This is
why they don't permit a second application in a season here. You may as well
just double the application rate initially 'cause the first application is
still there.
Merit works to prevent the new, young grubs from feeding. They ingest it in
very small quantities and then can't feed again which causes them to starve
to death. I have found it to be virtually 100% effective even when the
application is not perfect. Unfortunately the adult grubs are just too big
and strong to be effected. Fortunately they will pupate into June Bugs and
fly off and bother someone else in the next spring, or following one. Merit
should eliminate your grub problem, but you have to be patient.
You are right when you say now is the right time to apply it.

Large grubs have too much body mass/fat, they can survive the
very mild active ingredient in Merit.
We use dylox to kill bad infestations of large grubs, not Merit.
As was mentioned, merit is designed as a preventative.

Thanks for your reply Peter.
But still I don't understand why it is detrimental to have too much Merit or
have it reside for too long.

Peter:
Part of the answer is on the package label for Bayer Advanced Lawn
Season-Long Grub Control, which says:
"HOW TO USE TO CONTROL GRUBS:
"WHEN TO APPLY: Apply once anytime from May through mid-August. For
best results, apply Season-Long Grub Control before grubs... hatch.
Contact your County Extension Agent for the ideal dates to apply in
your area."
What the label doesn't say is that if you already have any but the
smallest of grubs chewing on your grass roots, the Merit stuff won't
have any significant effect on them. However you can kill them with
something else, such as Bayer Advanced Lawn 24 Hour Grub Control (in
which the active ingredient is Dylox). If you have yellow or brown
patches developing in your lawn, check to see whether there are grubs
in the soil below. If there are, zap the whole lawn with Dylox, which
will clear out all the active grubs. The Merit you already applied
should take care of any new grubs that hatch this year.
Next year you may do better to apply the Merit product earlier in the
year, before any grubs hatch - exactly when depends on your location,
but there's no harm in being two or three weeks early, and a lot to
lose by being two or three weeks late.

Steveo, you are only half right. The Merit will protect Peter's lawn
from grub damage this fall (to the extent that the lawn is not already
damaged by grubs that had hatched and started growing before he
applied the Merit).
But next spring is a different story. Even if there are no grubs in
Peter's lawn this fall, there may be lots of them happily munching
away on the grass roots next spring unless Peter applies Merit again
in the spring before the eggs hatch. Remember it's not the grubs that
lay the eggs, it's beetles, and beetles can fly in from anywhere.
Merit in the grass roots this fall won't prevent beetles from
depositing eggs that lie dormant in Peter's lawn until next spring.

Hey dumbass, if he doesn't have grubs this fall, he will -NOT- have
them in the spring either.
School yourself in control products next time, before you run your

Sorry to say, but I am not sufficiently informed on Merit.
But I certainly find the invective on this list objectionable.

Anyone who thinks grub eggs will lay dormant until next spring
is clueless.

Steveo, thank you so much for displaying your vastly superior
knowledge and for finding sufficiently vile words to describe my
rotting intellect and stinking carcass.
Perhaps, o enlightened one, you could now explain how Merit applied
too late to kill some of the grubs that hatched this summer would
prevent those grubs from burrowing downwards after their summer and
early fall feeding, remaining between four and eight inches beneath
the soil until next spring, and then rising back up towards the
surface in the spring and again feeding on the roots of Peter's grass.
(Won't this mean that, in mid and late fall, Peter's grass will appear
to be free of grubs, and yet there may be lots of them happily
munching away on the grass roots next spring? And isn't the obvious
way to prevent this the application of Dylox or something similar now,
before those growing grubs do any more damage? No, that can't be right
because you have declared:
> if he doesn't have grubs this fall, he will -NOT- have
> them in the spring either.)

The answer is simple, newbie. Those grubs have already pupated into
beetles..get it? Those beetles layed eggs for the next generation,
and Peter's merit application will protect his lawn from -those-
grubs.
If you don't know what the hell you're talking about, keep your
pie hole shut. You do more harm than good!

Steveo, the "mindless drivel" you snipped is carefully researched and
totally accurate. You are the one who is not getting it, so I guess
I'll have to spell it out for you very simply.
Adult Japanese Beetles appear in the spring. They fly around. They
feed on various plants. They mate. The females lay eggs in the ground,
then eat some more plants, then lay some more eggs, and so on until
they have laid maybe 50 or 60 eggs.
Typically the eggs hatch in a week or two, releasing small grubs into
the soil.
The grubs then feed all summer long on grass roots and other organic
material near the surface, and grow steadily larger.
In late September or early October, depending on the location, the
grubs burrow 4 to 8 inches downwards into the soil where they
hibernate for the winter. Once they burrow downwards the grubs are not
eating grass roots any more, but they may find some other organic
material to eat, at least for a while.
In early spring, the grubs move back up towards the soil surface. When
they find grass roots, etc. they begin to feed again. They haven't
eaten for quite a while, so they tend to eat a lot if they get the
chance.
Later in the spring, the grubs pupate for a couple of weeks at a depth
of two to four inches in the soil. They then emerge as newly formed
adult Japanese beetles.
Now let's apply this information to Peter's case, which started this
whole discussion. Peter has told us that he applied Merit to his lawn
on July 13th.
If Peter applied the Merit early enough to kill all the grubs that had
already hatched this year, he should have no problem. The Merit should
quickly kill all grubs that hatch later this season.
But if some of the grubs that hatched this year had grown large enough
by July 13th to survive the Merit, they will continue to grow and feed
in Peter's lawn for the rest of the summer. In the fall they will
borrow down to hibernating depth, and if Peter then checks the grass
roots for grubs he won't find any. But they will still be beneath
Peter's lawn, and come next spring they'll be happily chewing on the
roots of Peter's grass again.
And so when you said:
> Those grubs have already pupated into
> beetles..get it?
you were totally wrong. The only grubs that have pupated into beetles
this year are grubs that hatched last year.

Is late June to early July considered Spring where you live?
You said "grub eggs would lay dormant until next Spring". I
Say you're full of shit.
Learn the beetles life cycle before trying to advise people
on their control.
