Harpin Protein

[Reweed]

Seems like the best place to pop this thread.

Does anyone have any experience using Harpin protein on their plants? I sourced some from a hydroponics shop and am testing it this year, but like a right flapjack i sprayed every plant and didn't leave any unsprayed so I could compare results.

Hi Reweed, just had a quick read about this and it sounded quite good but then I got to the bit that said it is concentrated from the growth medium of genetically modified E. coli and that has put me off!!

Don`t think I`ll be trying it after that.

yeah. there is that. i'll see if i can dig up the article i found. It's been used commerically for years, so i'm pretty sure i'll have consumed it before.

Plus i'm not really bothered about organic, although technically the ecoli bacteric is an organism so i maybe ok.
