What's the stance of Chlorpyrifos in the states?

Looks like it was banned for home use in 2001 but farmers and golf courses can still use it.

 

[tomartom]

I use it here in Aus, long pants, gloves mask and goggles though. I will probably move away from it though when I finish the bottle.
It is broad spectrum, and has some residual

Anything else that can be used that doesn't cost $160-$180/bottle?

Just exploring options before investing into a 2.5gal container of product.

just curious as to what grub control product you have found thats $180/bottle? chlorantraniliprole is only $40 at Lowes/HD and one bag should cover your 4k of lawn

Dylox is $180 and I found the Bayer Sevin SL or whatever for $130/bottle.

@iFisch3224 dylox is a curative product. You use it to kill the big live grubs. It last a few days in the soil. I don't recall Sevin being good for grubs.

Chlorantraniliprole is a preventive product. You apply it in spring and it stays in the soil for a few months. When the insects lay eggs in the summer, the product prevents them from developing into grubs. This way to prevent the cycle.

This article from MSU goes into more detail. MSU Grub Control

I think the Bayer Sevin (Carbaryl) can be used as a curative for grubs, but it is not labeled for use on home lawns.

The red bottles of "Sevin" found in box stores has transitioned to a new active ingredient - Zeta-Cypermethrin. I'm not sure if it works on grubs.

at the high rate of 7oz/k 2.5 gallons of dylox is enough for 11 apps on 4k of lawn.
chlorantraniliprole ($40) in mid april and Imidacloprid ($35) in late june worked well for me

Last year I had a massive grub infestation and ruined lawn. While I'm reading forums and articles I wonder if I made mistake when I applied manure fertilizer in spring. "Female green June beetles lay eggs in the soil of sites with an abundance of decaying organic matter- thatch, animal manure, or organic fertilizers. This ensures food for developing larvae."

On the other side, I wonder if I help the lawn with humic acid, which promotes root growth.

This is true. I had to make an Amazon return since they started shipping the new stuff

Just more food, for developed larvae! I know as, with the best of intentions, I was procuring all manner of organic matter from local farmers and had no idea the absolute nightmare I was setting myself up for. "Attracting" egg layers was the least of my problems; one or more loads contained wire worms for which there is no chemical curative - you find them in your lawn and you need to run, not walk, to order up some live beneficial nematodes. Needless to say, it was a terribly ex$pen$ive le$$on! :roll:

After my massive grub outbreak and subsequent grub damage last fall, I dropped a granulate application of the Bayer 24 Hour GrubKiller Plus as a curative approach. It uses Trichlorfon.

Since I have no idea where in the life cycle my particular grubs are (and I probably have several varieties), my plan this year is as follows:

Mid April- Trichlorfon application via Bayer 24 Hour GrubKiller Plus as another curative treatment
June- Imidacloprid via Dominion 2L liquid. The first of the preventative applications.
September- another GrubKiller Plus. Should be the last of the curative treatments. May not be necessary

 

[Pawel]

I put out Milky pore last spring...supposed to last ten years! We shall see!

that's what i want to try this year (it does say it might take more than one application so i wonder if i should use it with grub-ex or something)

 

[Ware]

If you plan to use Scotts GrubEx for preventive grub control, now is a good time to apply it. This MSU article states that its active ingredient (chlorantraniliprole 0.08%) should be applied between April 1 and May 30 for best results. This is a couple months earlier than the recommended timing for some other active ingredients/products.

Bumping this as a reminder for anyone who plans to use GrubEx this year. I will be putting mine down within the next week or two. The 10k ft2[/sup] bag on Amazon was a little cheaper than buying (2) 5k ft[sup]2 bags at my local box store this year. :thumbup:

Save yourself the time and expense. Just apply chlorantraniliprole in the month of April.

The biggest issue related to performance of all preventative grub treatments, granular or liquid, is not watering in well enough to get the active ingredient past the thatch layer. One trick you can use to increase your odds of getting the AI on target is adding a wetting agent to a liquid app.

I went to Lowe's this morning. The website said they had 71 in aisle 23. No there and they had no clue. I will hit another one.

 

[cnet24]

Anyone have experience with Merit? Domyown has a 30lb bag for only $59. Looks like the app rate is 1.4lbs-1.8lbs per 1k.

 

[Kissfromnick]

Merit 0.5 Granular Systemic Insect Control does the trick.

 

[sportsman10]

Ace Hardware has a 14.35 lb bag of GrubEx (5K sq ft) on sale for $20.99. That's about $3 less than big box stores in my area. Also, you can get an extra $3 off if you're an Ace Rewards member (free to join). Final price for me was $17.99+tx for 5K coverage. Sale ends 4/30/19. Limit (2) per membership.

If they pull out the pocket computer it's safe to say they're clueless. I start walking away when it comes out.
