It looks like grubs munched on my lawn this summer (if you dig a patch of
dirt there are quite a few of them). So, I'm planning on over dressing my lawn and laying new seed. Would it be helpful to lay grub control down first (to kill the grubs that are there), dress it and lay seed, or just wait until next year and start then. Is it even too late to put grub control down (I live in coastal NH). Thanks in advance for any advice. -Kevin -- Don't forget to check out my cartoon, Virtual Humor! http://www.kevinduffy.net/vh.htm |

I don't know what's approved for use in your state, but a local gardening center will set you straight. I would try to go after the grubs this fall and then worry about sorting the lawn out next spring. Grubs are root-feeders and to kill them you have to get the insecticide down to the rootzone of the grass plants. Make sure that you water in the application right away, or better still lay it down in the rain. If you topdress the lawn now it will make it that much tougher to get the insecticide down to the rootzone. Check the lawn a couple of weeks after the application and see how many healthy grubs you have left. They are a tough insect to kill and normally a kill rate of 75% is very good. If you still have a serious infestation you will still have time to do a second application this fall. Good luck. Peter H |

The grubs feed on the roots during the winter. The crane flys do thier mating
and birthing during the summer. Not sure of your area, but might be ok to put down grub control now or it might be a waste of money. Contact your local nursery.

As temperatures decrease, they go deeper into the soil and become inactive until spring. As Peter pointed out, a general purpose insecticide like diazinon can still be used now and is worthwhile, as the grubs are still small and hence easier to kill. |

As Peter pointed out, a general purpose insecticide like diazinon can still be used now and is worthwhile, as the grubs are still small and hence easier to kill. While I'm not an entomologist, I'm not sure a cranefly qualifies as a grub. The term grub is generally used to describe the larvae of beetles, eg june bugs, japanese beetles, not flies. These are the larvae that are causing the majority of the problems in lawns in most of the US. Here's a good link to an agricultural article describing grubs, their lifecycle and affect on turf: http://www.gov.on.ca/OMAFRA/english/...cts/97-023.htm Note that the larvae description of being C shaped, 6 legs, etc. also does not fit the cranefly larvae. They indicate that all the grubs they describe go deep in the soil as the temps drop, then return to feed as temps rise again in spring. |

" I find that very hard to believe.
Peter H" Yeah, some entomologist. After that one, I did a little search on craneflies. Every link indicates that they are not a major problem in turf grass, any damage is usually minimal, and that rarely is any pesticide recommended to control the problem. Certainly doesn't sound like the grubs we know. "Peter H" wrote in message le.rogers.com... "Die Spammer !!!" wrote in message ...
