Do you know the classification of your soil? What kind of agriculture was it used for if any?

Berrycrush Where are you located?

There are certainly lots of Dundee's.

Let us know the results

I would say in theory it could be done, because you have living genetic material, but my guess is in a laboratory setting. It won't hurt to experiment. let us know how it turns out.

Take a look at fixed copper sprays. http://ipm.ucanr.edu/PMG/PESTNOTES/pn7481.html

The first year I had thousands of them. This year and last year many many less. I am hoping due diligence affects the breeding population. I have read that milky spore is more effective in the South, because in the North the low temps kill the colonies.

They are more active in the evenings. I don't spray the vines, just the bugs. I keep a spray bottle handy when I'm in the vines and the Beetles are out. Mine are done until next year. The Sevin has worked great for me, both old formula and new. You have to kill them each day, because each day...

Sevin. I walk through and shoot every JB I see. Every day. Until they are gone.

One clever trick is to avoid vinifera.

I wonder who eats the midges on the food chain?

No matter how you treat the soil now, you are dealing with tons and tons of material. Deficiencies might easily show up later and it could be helpful to do petiole analysis down the road and apply nutrients foliar. Say hello to agriculture, on a micro scale.

What is growing in the area where you plan to plant the vines? Does the soil have healthy growth currently? I would say break the vine area into a 1000 or 2000 square foot area or areas. Then break down your acre nutrient recommendations to a 1000 k level. About the best you can do is till it in...

I think I answered my question. Grape Tube Galls, associated with small flies called midges. https://en.wikipedia.org/wiki/Schizomyia_viticola

How about a Friend or Foe thread? Can anyone identify the insect laying these eggs?

Ibglowin Nice looking vines.

I don't know if it has been mentioned in this thread, but neem oil and spinosad are worth looking at as alternatives.

It is too late to replant this year. Spray with Sevin now and get rid of them. Then see what happens this year with them.
