I played w/ messenger this year on a few things, mostly not aroids. The A. bulbifer I gave it to did well but I really didn't have any kind of control to compare it to. The results were not overly dramatic compared to the other species I grow which didn't get messenger. I also gave all my amorphs a lot of bloom booster so it's hard to know what effect the messenger had. Another thing I tried was adding powdered aspirin (acetylsalicylic acid) to the fertilizer mix. I know, very "mad scientisty" but I read that it can help plants increase thier own immunity to things like fungus. Again no controls, lots of fert but both plants did well and tuber size increased from the year before.

Interested to hear others experiences w/ messenger.

I just bought Messenger this fall to try next spring. The fact that it's a protein and I could find scientific papers on it sold me--I'm a sucker for "real science" kind of things.

I used it on one that I thought was a goner and was surprised to see it some back to life really fast. I only sprayed it once and in the spring it will get sprayed! I'm a believer! Here is our webshot site.
