GrubEx Return or Apply NOW in NJ

Postby bongobyll » May 19th, 2017, 5:02 pm

Life got away from me and I know I should have applied earlier, but my life and the weather didn't cooperate this year.

I had grubs last year and applied Bayer 24hr last year and planned on using GrubEx this year... but didn't.

I've seen grubs in my beds already and wanted to do another round this year since I had known damage last year. I tried to use what seems like the more environmentally responsible GrubEx, but wanted confirmation that it is too late. I have irrigation (city water) and a large lawn. I am not against the cost to water any product in if it still is worth it (seeing how I totally missed the perfect week last week).

Should I still apply GrubEx this late in the year or use a different product soon/now? If a different product, recommendations on what and when would be appreciated.

I like the 101 forum because I feel more comfortable asking my "should have known better" questions, so thank you for creating it and taking the time to answer.

This Michigan State University article recommends the application of GrubEx (chlorantraniliprole) between April 1 and May 30. The article actually say: "so it can be applied any time after the grass turns green in the spring".

Read that article. You still have time but don't delay it. Since you had grub problems last year you really need to get some protection.

Thanks G-man, that article is what lead me to choosing grubex (nicer to the honey bees). Just thought I've seen others point out the northern location of that article, affecting the exact dates of drop time and was afraid I missed my window.

Hopefully with the irrigation helping the natural precipitation, it will work into the ground quickly enough.

Thanks again

For what it's worth...

I was in the same situation last year and applied on May 17th. I knew it wasn't ideal to be on the late side, but I wanted protection. It worked fine...but I had also applied Grubex in 2015 as well, and Imidacloprid at least the year before that, if not two.

My local garden center recommended applying GrubEx on May 20, last year for what it's worth.

I believe I'm in zone 6b, and May 20th is the very latest I'd feel comfortable putting it down, unless the rainfall in late May through June was highly above typical levels.

Depends what you're putting down - read that article. It's about the AI, not brand. chlorantraniliprole is almost past application timeframes.

it is highly recommended that products containing imidacloprid, thiamethoxam, clothianidin (Grubbex contain clothianidin) be applied [/color]and irrigated into the soil in June or July. If applied in early spring, the pesticide may move through the soil or partially degrade by the time the grubs hatch in late July. If applied too late, preventative products may not be effective as they work best on small grubs.

The information you cite about grubex is several years out of date. (At least for grubex sold here)

The label on Grubex indicates the active ingredient is Chlorantraniliprole. Everything I've read about it says to apply no later than mid-May for best results.

+1

My standard recommendation to learn about grub control products is an excellent article from Michigan State University which is updated annually:
How to choose and when to apply grub control products for your lawn
.

The article will tell you to apply chlorantraniliprole "as early as April" and that "applications made before June are more efficacious than June or July application."

The current Grub-Ex (also known as Grub-Ex1) contains chlorantraniliprole. Before 2015, it was a different formulation, which had different application timing. Accordingly, one has to be careful when looking at online articles saying when to apply Grub-Ex, as the information in older articles is now, well, out-of-date. ;)
