Has anyone tried any Harpin protein based products with their AG plants?

My thoughts are if the product (below, called Halo) can be used to boost the plants growth so that it is more advanced/established prior to fruit setting (+ the additional listed benefits as per the lins below).

I am more concerned as to if it would have any negative impact on the plants ability to grow a big one.

Thanks

This link is the product of interest:

This link provides a little info on how it works

Tried it a few years ago. Nothing noteworthy. Likely a waste of money, and at worst it could cause a faster ripening time. I might try it again in the future on a test plant, but it's nothing that i'm too excited over.

Thanks Pumpkin Shepherd, brought me back down to reality.

I guess one way is to have two identical patches and compare the effect.

I did find an old post from J.D and have emailed him to find out a little more.

I have used the product Messenger the last three years. It works, especially if plants are subjected to high humid greenhouse conditions throughout the year. No powdery molds or mildews even late in the season. Check out 2006 diary of the Wallace 1068 plant, one of the coolest and wettest on record. I don't mention the product but it is used every three weeks throughout the season. Am using it again this year, another cool wet year, no powdery mildew either.
