    I still have 20, 15,000 ft2 lawns that I need to apply Merit/fert still. No rain in 21 days, lawns are non irrigated and no chance the homeowners will water fertilizer in after it is applied. I just need some rain so I can apply Merit so it gets watered in.

    How long to you think I have until my effectiveness window expires? I know that the grub pressure will be low since these lawns are non irrigated, just looking at timing-Thanks!

    If they don't water why apply it the grubs don't really like hard soils.

    Because the customer requested the application?

    These lawns have had grub damage in the past, that is why these customers are insisting on having Merit applied. Yes the soil is ROCK HARD now so the beetles won't like laying their eggs there now. However, I'm hesitant about not apply the Merit, because if we get a rainy end of July and these lawns get grubs, I look incompetent to the customer.

    Spray needs watered in within 24 hours. You got a little longer window with granular. Also I would say we are getting pretty close to the end of that window, if not there already. I have seen masked chafers since the beginning of May, Jap. beetles since 2nd week of June, but not the masses usually seen. Not many calls to spray shrubs for them. :( Me thinks the dryness is effecting there pupating. Plus side, irrigation business is CRAZY BUSY!

    Eggs are probably just being laid and if there is no moisture the eggs will not hatch anyway.

    The eggs have to be hydrated.

    If it stays dry the chances of having a grub problem should be much less.

    I have always heard you can apply through August 15th as they are still small enough.

    Application date for grub control has never been an issue for us but it may be this year.

    We are not applying until it rains so we may not even get it down this year.

    OH WELL!!!

    Our 7 day forecast calls for the same, no rain, no rain and more of no rain.

    It looks like I may just skip the Merit/fert and just hope for no grubs.
