Dylox is the fastest. But not labeled for vegetables. Diazinon is though.

Chickens seemed to do the job for us. If you have the space and don't mind having them...
But we also use Grubex every year in the spring( Which is a Systemitic) So it has reduced the grubs ALOT... So that might be somethiung you do in the fall or in the spring right away..

I am usuing Triazicide on my lawn grubs. Kills fast and is also the same stuff labled for use in the garden. I used it last yr in my garden and it did a good job in that i had very little cuke dammage, no svb dammage (even though I had pleanty of them) and only small stink bug dammage. The stink bugs where the hardest to controll. Maybe I should have been spraying on the ground and on the fruit not just the plants. It uses the same chemical as warrior t only in a lower concentration. The chemical is lambda cyhalothrin. I didn't know till this past winter that it also has a systemic action.

My Skunks have been doing a fine job. They also turnover the soil. You may borrow them.

Lambda-cyhalothrin has no systemic action.

I add lots of fresh manure every year, and so therefore I am always fighting a grub problem. The past few years I have completely solved this problem by not adding chemicals nor pesticides which will also do harm to your worms and possibly some of the microbes in your soil. The method I personally favor is the addition of nematodes which paricitize the grubs then reproduce to kill more grubs. this method has eradicated grubs from my patch, and works very quickly and efficiently without any negative after effects. Their cost is pretty cheap for the brand I use ( THE GARDIAN NEMATODE ) at about $8.00 per million, as I treat with approx. 1 million per 400 sq.ft. good luck JK.

And oh forgot to mention as I mispelled ( THE GUARDIAN NEMATODE ) is also beneficial to killing a wide variety of other not so wanted pests in your soil as well... If you wish to know more about these very small and beneficial critters, check out this link...http://www.hydro-gardens.com/nematodes.htm

Thanks Tremor.. So much for trained garden center personell. The person that told me that also told me to be carefull as Spectricide also markets other chemicals under the triazicide name. is that true?

Are you sure they were grubs? I did some digging in the compost area around an old tree stump and am finding what looks like Cicada pupae If so there is gonna be a bunch of them this year!!

That is true Eric. Confusing too. Read each label for the actual active ingredient. They offer some desirable molecules. But they bundle & package them in ways we need to watch for.

I wish I knew where the Systemic~Lambda-cyhalothrin thing came from. It made the round a couple years ago & even found it's way into Don's 3rd book. No matter. It is just as false now as it was then.

Now about Ray's grubs. They're European Chafers. Nematodes can be used to prevent them. But he's breaking ground on a new patch in an area that used to be lawn. He's finding third instar grubs that are too big for Nematodes to kill. They don't seem to mind cold weather like other white grubs (scarab beetle larva) do.

See this U-Mass link:

Like I said. Proxol or Dylox (Trichlorfon) is the only choice. Period.

Chafers won't come back because the patch won't be growing turfgrass during the Beetle's egg laying period later this year (late July). Most of the rest of the country doesn't have to worry about Chafers.

Tremor, I have used the nematodes as I had mentioned above to not only prevent grubs but also to erradicate a very concentrated and productive population of third instar grubs. Granted they were not the European Chafer, but according to the info I have,the Eueopean species is still in the Scarab family and so should be just as susceptible to the attack of the nematode. This method of erradicating third instar grubs has not only been used and been successful by myself but also by numerous other growers in my area.I just feel any method of control other than pesticide/chemical is always the first choice before having to resort to the drastic measures of chemical application. Thanks, JK.

It sounds like parasitic Nematodes have come a long way since the days of Vector Biological back in '94-'95. Those were some of the first Nematodes ever offered commercially. They were fair at best on second instar grubs & failed miserably on third. Shipping was via Next Day UPS (only) in a double insulated cooler with dry ice. When they arrived, you had 24 hours to use them or they died. Once mixed the user had 10-12 hours to apply if the sprayer was kept out of the sun. If the spray dried before being watered in, the nematodes died. So cloudy/rainy days were the only choice on large areas. The wholesale cost back then was about triple what you're now paying retail. Quite an improvement.

If you've seen this new variety work on large grubs then I'll stand corrected.

I would still look into this Nematodes cold weather performance. It has been unusually cool here so far this April.

That aside, this one may be a winner.
