When is a good time to spray this on the patch before planting to kill vine borers that are in the soil.
Like to hear some stories on what people do for Vine Borers before growing time starts.
thanks alot, Brooks
Steve Ill be calling you soon,Your phone was busy all day, I think its your cell number, not sure.

My cell rings every 2-3 minutes this time of year. But no Ohio numbers today. I'll email you my new office number later.
Merit isn't labeled for SVB. It does an amazing job on Cucumber Beetles.
That said....
Last year a friend did one early Merit for Cuke Beetles. It worked.
But he never did the 90 day reinforcing application. I visited around that time. He was in the patch cutting SVB infested secondaries from the plants.
I convinced him to leave a few infested vines for experiment. We made a dilute mixture of Merit in a watering can & drenched the secondary roots in the area of infected vines.
48 hours later the larval stage borers were dead.
So while the efficacy data that was collected by Bayer supports supression of SVB's, none of the Imidacloprid products are specifically labeled for this use (even though some supression occurs).
Well timed applications obviously can offer some control. But I would rely soley on this approach. Some residual contact sprays are mandatory where SVB pressure justifies.

What rate for merit or Imidacloprid products should be used? Should it be more than the 16-24oz/acre that is reccommended for the cuke beetles? I followed OSU's Ag guidelines of Admire to control Cuke beetles and was hoping to control the SVBs as well. I will use a contact as steve mentioned.

Use the same rate. I still advocate a preplant treatment a week or two prior to planting. Be sure to lightly reinforce the actual mound & seedling since planting disturbs the area & new roots can take days to find the Imidacloprid in the sorrounding soil & start translocating.
But where I used to think that 90 days was good for a reinforcing application, I now think we should be repeating the application at 60-70 days (around here) if any kind of SVB suppression is to be expected.
But here's the deal....the adult SVB will still lay eggs if no contact spray is used. So the developing larva would have to do at least some vine feeding to pick up a lethal dose. This could involve a large amount of plant material before enough Imidacloprid is ingested to cause mortality. True competition grade plantings cannot afford any feeding.

Tremor, the Merit I bought says that it is to be broadcast somewhere around 1 month before planting so that it can rain on the patch.The roots will then be able to pick it up. Then it states another appliation in about another month. Should this do the trick in NC, with occassional Sevin being sprayed when needed?

Daconil?? What would be another Chem. that would go with this as an overall spray program for fungus and etc, rather than Quadris$$? Kocide was suggested also for later in the yr. This is for NC patch.

Toby, The information you have is accurate.
Daconil is a great all-purpose contact fungicide & can be used in conjuntion with Quadri$ or Heritage for even better results.
Kocide is a Copper Hydroxide preperation. It would be usefull for Angular Leaf Spot early in the year if you get ALS. I suppose oif growers in NC are using Kocide it's because they saw Downey Mildew last year. Is this correct?

Can you tell me more about Merit? I have two dogs who frequent the back yard. Is it safe for them?

The active ingredient in Merit is Imidacloprid. Bayer manufactures another version of Imidacloprid

Woops....wrong button...
The active ingredient in Merit is Imidacloprid. Bayer manufactures another version of Imidacloprid called Advantage which is used directly on your dog to control Fleas. It is an oily topical skin treatment.

Thanks Tremor.
And I'm sure you've heard it a million times, but... Thanks for all of your help on bp answering questions like this. I know you have answered a few other golden questions in the past that I was looking for the answer to, whether I was the guy asking, or someone else asked and I learned something new from it.
I love my 2 little puppy dogs and certainly don't want to harm them growing bp's. I recall a post I think from last year where someone's dog died from some type of pesticide or something. Can't recall the exact details.

I understand. I once paid $300 to determine the cause of death of a 12 week old kitten we thought had gotten into something. It was a brain anurism (sp?).
Just keep the puppy out of the patch. Neither will benefit I assure you. LOL

You paid 300 bucks for an autopsy on a kitten Steve? Must have been an anurism for sure ! How did the doctor cure it...you seem sane now..........lol
