I was planning on applying "MERIT 0.2% 24-0-8 40%PPSCU 2%FE" to my own lawn on July 1st but it doesn't look like we are going to get rain for another week or more and I won't be able to water it in. Should I just wait until just before rain is expected.

Either rain or irrigate as per the label - especially if you're going to be putting out w/fert&iron.

yes most of these products need 1/2 inch of h2o to activate

I was told by my supplier that if Merit is not watered in with 72 hours it will loose over half of it's effectiveness.

It needs to bond with the thatch and organic material...the grubs will be located there anyways

Where in the Northeast are you if you're not expecting rain for at least another week? I'm in NY; can we trade weather???

Seriously, though, if you're at least as far north as I am, what's the rush? You'll be fine if you have to wait another week.

Unless they are at the base of the root zone.

Unless they are at the base of the root zone. If the ground is dry you won't find a Billbug Larvae feeding in the thatch .

Skip the merit, with all the rain they are either gonna drown or have to build an ark anyway:dizzy:

Seriously, you should be good on the window of application for at least another week or two, dont get nervous. I have applied as late as July 30 in the past and not had any ill effects. Merit does take less water to activate than some other products but still needs to be watered in.

I applied Merit 75 last week with Chelated Iron (12oz per 1K sq/ft)....

Read the label. easy to figure out...The kicker is when to apply it is MIA on the label.

I am more curious how long merit can last on a lawn before being watered in. I know it won't be affective until its watered in, but say it doesn't rain for a few days, will the merit lose its affectiveness when it finally does rain?

We apply Merit to fit our work load and not pending rain. Never had a bad year of Grub control.
You will nver get perfect application conditions.

It takes several weeks for serious photodecomposition on merit.

Found a chafer beetle in my tomato garden last weekend, when i was weeding. I think that the massive amount of rain and cold weather has neg impacted the populations this year. We got over 9 inches of rain in one week. It has rained 26 days in June here, some days all day or half days , but we got 26 days of some form of rain or drizzle.

From what I've heard Merit is very stable and can sit on a lawn for a while. The worst thing that can happen to a merit app. is a little rain, enough to wash merit off the fertilizer, but not enough to wash it into the soil. How much rain that is depends on soil type and the amount of thatch you're dealing with.
